Step-by-step explanation:
[tex]2(4x + 1) = 4(2x + 5)[/tex]
[tex]8x + 2 =8x + 20[/tex]
[tex]\nexists x \in \mathbb{R} \text{ That makes the equality true}[/tex]
The equation has no solution because no matter what the value we plug for [tex]x[/tex] in the equation, it will not be true and will lead to a contradiction. This is the meaning of not having a solution.

Answer:
if x = 12; y = 40
if x = 3; y= 13
Step-by-step explanation:
if x = 12 then,
y = 3(12) + 4
y = 36 + 4
y = 40
if x = 3 then,
y = 3(3) + 4
y = 9 + 4
y = 13

Jill can run 20 miles in
three hours at a steady
rate. How many minutes
will it take her to run
five miles?
Answer:
45 minutes
Step-by-step explanation:
Change 3 hours to minutes
1 hours = 60 minutes
3 hours = 180 minutes
Using proportions
20 miles 5 miles
------------- = ----------------
180 minutes x minutes
Using cross products
20x = 5* 180
20x =900
Divide each side by 20
20x/20x = 900/20
x =45
45 minutes
Answer: 45 minutes
Step-by-step explanation: 20 miles in 180 minutes, 5 miles is 1/4 of 20 miles so you divide 180 by 4 which gives you 45
Last week Isaiah and his roommates ate 3/8 of a carton of yogurt, and this week they ate
7/12 of a carton. How much more yogurt did they eat this week compared to last week?
Answer: 5/24
Step-by-step explanation:
The problem is 7/12-3/8. I got a common denominator of 24, then multipled 8 and 3 by 3, and 7 and 12 by 2. The problem is now 14/25-9/24, which equals 5/24

Two cards are selected from a standard deck of 52 playing cards. The first card is not replaced before the second card is selected. Find the probability of selecting a seven and then selecting a nine.
The probability of selecting a seven and then selecting a nine is
(Round to three decimal places as needed.)
Answer:
0.006
Step-by-step explanation:
On the first draw, there are 52 cards, 4 of which are sevens.
On the second draw, there are 51 cards, 4 of which are nines.
The probability is:
(4/52) × (4/51)
= 4/663
≈ 0.006

Answer: 22
Step-by-step explanation:
Answer:
22
Step-by-step explanation:
Don't worry, don't worry child. Oh, geometry. How lucky are you: finally knowing this treasury of humanity. I'm jealous now. Haha.
In the annex, you can see what is happening :)
Look that, if a and b are paralels, 4x + 28 is External Alternate of the Opposite Vertex of 116, which is also 116. Then, they have the same value: 4x + 28 = 116.
If you don't remember those concepts, review the initial part of geometry. The proof of that is quite simply, moreover is easy to mentally deduce that.

CAN SOMEONE HELP ME PLZ THIS WAS DUE LIKE 5 minutes ago!!
Answer:
-4[tex]x^{2}[/tex] - 6
Step-by-step explanation:
First you have to add the two polynomials. Write the first equation then line up the second equation below the first making sure to keep the columns correct. [tex]x^{2}[/tex] goes in one column, x goes in the next column and the whole numbers go in the last column. Also be sure to have the correct signs of those columns. It should look like this:
4[tex]x^{2}[/tex] - x + 1
PLUS -6[tex]x^{2}[/tex] + x - 4
-----------------------
-2[tex]x^{2}[/tex] + 0 - 3
Note that the middle x turns to 0 because you're subtracting 1x from 1x which is 0.
You can now write the SUM as -2[tex]x^{2}[/tex] - 3
Now they want to know what twice this sum is so multiply it by 2
2 ( -2[tex]x^{2}[/tex] - 3) = -4[tex]x^{2}[/tex] - 6

18.75 + (12.8 x 3) - 16.28
Answer: 40.87
Step-by-step explanation:
Answer: 40.87
Step-by-step explanation:
First you would do 12.8x3 because it’s in parentheses you would then get 18.75 + 38.4 - 16.28. You would then do 18.75 + 38.4 and get 57.15 then subtract 16.28 from that and get your final answer 40.87
which property of equality is 4x-3=x+9
Answer:
Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality.
5+3−2=6+2−2
This gives us a couple of properties that hold true for all equations.
The addition property of equality tells us that adding the same number to each side of an equation gives us an equivalent equation
ifa−b=c,thena−b+b=c+b,ora=c+b
The same goes with the subtraction property of equality.
ifa+b=c,thena+b−b=c−b,ora=c−b
As well as it goes for the multiplication property of equality. If you multiply each side of an equation with the same nonzero number you produce an equivalent equation.
ifab=c,andb≠0,thenab⋅b=c⋅b,ora=cb
And naturally this goes for the division property of equality as well. You can divide each side of an equation with the same nonzero number to produce an equivalent equation
ifa⋅b=c,andb≠0,thena⋅bb=cb,ora=cb
This gives us a way to change an equation to our own liking. Anything is acceptable as long as you do the same thing on both sides.

(X^2+x-12/x^2-x-20)/(3x^2–24x+45/12x^2-48-60)
Answer:
(4 (x^4 - 20 x^2 - 12))/(3 x^2 (9 x^2 - 32 x - 144))
Step-by-step explanation:
Simplify the following:
(x^2 + x - x - 20 - 12/x^2)/((15 x^2)/4 + 3 x^2 - 24 x - 60 - 48)
Hint: | Put the fractions in x^2 + x - x - 20 - 12/x^2 over a common denominator.
Put each term in x^2 + x - x - 20 - 12/x^2 over the common denominator x^2: x^2 + x - x - 20 - 12/x^2 = x^4/x^2 + x^3/x^2 - x^3/x^2 - (20 x^2)/x^2 - 12/x^2:
(x^4/x^2 + x^3/x^2 - x^3/x^2 - (20 x^2)/x^2 - 12/x^2)/((45 x^2)/12 + 3 x^2 - 24 x - 60 - 48)
Hint: | Combine x^4/x^2 + x^3/x^2 - x^3/x^2 - (20 x^2)/x^2 - 12/x^2 into a single fraction.
x^4/x^2 + x^3/x^2 - x^3/x^2 - (20 x^2)/x^2 - 12/x^2 = (x^4 + x^3 - x^3 - 20 x^2 - 12)/x^2:
((x^4 + x^3 - x^3 - 20 x^2 - 12)/x^2)/((45 x^2)/12 + 3 x^2 - 24 x - 60 - 48)
Hint: | Group like terms in x^4 + x^3 - x^3 - 20 x^2 - 12.
Grouping like terms, x^4 + x^3 - x^3 - 20 x^2 - 12 = x^4 - 20 x^2 - 12 + (x^3 - x^3):
(x^4 - 20 x^2 - 12 + (x^3 - x^3))/(x^2 ((45 x^2)/12 + 3 x^2 - 24 x - 60 - 48))
Hint: | Look for the difference of two identical terms.
x^3 - x^3 = 0:
((x^4 - 20 x^2 - 12)/x^2)/((45 x^2)/12 + 3 x^2 - 24 x - 60 - 48)
Hint: | In (45 x^2)/12, the numbers 45 in the numerator and 12 in the denominator have gcd greater than one.
The gcd of 45 and 12 is 3, so (45 x^2)/12 = ((3×15) x^2)/(3×4) = 3/3×(15 x^2)/4 = (15 x^2)/4:
(x^4 - 20 x^2 - 12)/(x^2 (15 x^2/4 + 3 x^2 - 24 x - 60 - 48))
Hint: | Put the fractions in (15 x^2)/4 + 3 x^2 - 24 x - 60 - 48 over a common denominator.
Put each term in (15 x^2)/4 + 3 x^2 - 24 x - 60 - 48 over the common denominator 4: (15 x^2)/4 + 3 x^2 - 24 x - 60 - 48 = (15 x^2)/4 + (12 x^2)/4 - (96 x)/4 - 240/4 - 192/4:
(x^4 - 20 x^2 - 12)/(x^2 (15 x^2)/4 + (12 x^2)/4 - (96 x)/4 - 240/4 - 192/4)
Hint: | Combine (15 x^2)/4 + (12 x^2)/4 - (96 x)/4 - 240/4 - 192/4 into a single fraction.
(15 x^2)/4 + (12 x^2)/4 - (96 x)/4 - 240/4 - 192/4 = (15 x^2 + 12 x^2 - 96 x - 240 - 192)/4:
(x^4 - 20 x^2 - 12)/(x^2 (15 x^2 + 12 x^2 - 96 x - 240 - 192)/4)
Hint: | Group like terms in 15 x^2 + 12 x^2 - 96 x - 240 - 192.
Grouping like terms, 15 x^2 + 12 x^2 - 96 x - 240 - 192 = (12 x^2 + 15 x^2) - 96 x + (-192 - 240):
(x^4 - 20 x^2 - 12)/(x^2 ((12 x^2 + 15 x^2) - 96 x + (-192 - 240))/4)
Hint: | Add like terms in 12 x^2 + 15 x^2.
12 x^2 + 15 x^2 = 27 x^2:
(x^4 - 20 x^2 - 12)/(x^2 (27 x^2 - 96 x + (-192 - 240))/4)
Hint: | Evaluate -192 - 240.
-192 - 240 = -432:
(x^4 - 20 x^2 - 12)/(x^2 (27 x^2 - 96 x + -432)/4)
Hint: | Factor out the greatest common divisor of the coefficients of 27 x^2 - 96 x - 432.
Factor 3 out of 27 x^2 - 96 x - 432:
(x^4 - 20 x^2 - 12)/(x^2 (3 (9 x^2 - 32 x - 144))/4)
Hint: | Write ((x^4 - 20 x^2 - 12)/x^2)/((3 (9 x^2 - 32 x - 144))/4) as a single fraction.
Multiply the numerator by the reciprocal of the denominator, ((x^4 - 20 x^2 - 12)/x^2)/((3 (9 x^2 - 32 x - 144))/4) = (x^4 - 20 x^2 - 12)/x^2×4/(3 (9 x^2 - 32 x - 144)):
Answer: (4 (x^4 - 20 x^2 - 12))/(3 x^2 (9 x^2 - 32 x - 144))
Mark was thinking of a number Mark added 11 to it then doubles it and gets a answer of 40.5
Answer:
9.25
Step-by-step explanation:
Mark doubled the number so we can divide 40.5 by 2 which is 20.25
Then we can subtract 11 from 20.25 because Mark added 11 to the number.

6/9 9/12 wich one is bigger
Answer:
9/12
Step-by-step explanation:
because I is the biggest number
Answer:
[tex]\frac{9}{12}[/tex] is the biggest
Step-by-step explanation:
I converted the fraction to a decimal by dividing the numerator by the denominator.
[tex]\frac{6}{9}[/tex] is 0.6... (6 is repeating)
[tex]\frac{9}{12}[/tex] is 0.75
When looking at these 2 decimals I know 0.75 is bigger.
Which means [tex]\frac{9}{12}\\[/tex] is the biggest.
