Solve the inequality.−2(x − 3) − 4 ≥ 3x − 5(x − 1)
Answer:
0>3 i hope it helps
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2(x−3)−4>3x−5(x−1)
Step 1: Simplify both sides of the inequality.
−2x+2>−2x+5
Step 2: Add 2x to both sides.
−2x+2+2x>−2x+5+2x
2>5
Step 3: Subtract 2 from both sides.
2−2>5−2
0>3
Select the correct answer.
The equation of a line is y=-3x - 2. What are the slope and the y-intercept of the line?
A. slope = -3 and y-intercept = 2
B. slope = 3 and y-intercept = -2
C. slope = 3 and y-intercept = 2
D. slope = -3 and y-intercept = -2
Answer: D
Step-by-step explanation:
The slope of a linear equation is the m value in the linear equation y=mx+b, in this case m=-3. The y-intercept is the b value in the linear equation y=mx+b, in this case b=-2.
If 4 tickets cost $35, what is the cost for 1 ticket?
A trail runner gets a new map of her favorite mountain. • Her old map has a scale of 1 cm to 100 m. • Her new map has a scale of 1 cm to 500 m. She ran a trail that was 40 cm long on her old map. How long is this trail on her new map?
PLEASE ANSWER
Answer:
The trail on her new map is 8 cm
Step-by-step explanation:
Here, we are interested in knowing the the length of the trail on the new map.
The scale on her old map is 1 cm represents 100 m
While her new map has a scale of 1 cm to 500 m
Now, running a trail of 40 cm on her old map, we need to get the actual distance.
The actual distance will be 40 * 100 = 4,000 m
Now, we shall convert this to the new map scale
We simply convert this to cm in the new map scale by dividing the 4,000 m by 500 m
That would be 4,000/500 = 8 cm
So the trail on her new map is 8 cm
Answer:
The actual distance will be 40 * 100 = 4,000 m
Step-by-step explanation: Now we have to convert the new scale map by dividing the 4,000 m by 500 m so that would be 4,000/500 = 8 cm
Help please! I just don’t understand
===================================================
Work Shown:
(angle HID) + (angle DIJ) = angle HIJ
(100) + (8x+11) = 21x+7
100+8x+11 = 21x+7
8x+111 = 21x+7
111-7 = 21x-8x
104 = 13x
13x = 104
x = 104/13
x = 8
Use this x value to find angle HIJ
angle HIJ = 21x+7
angle HIJ = 21*8+7
angle HIJ = 175 degrees
---------------------------
Extra info:
You can also use that x value to find angle DIJ
angle DIJ = 8x+11
angle DIJ = 8*8+11
angle DIJ = 75
Then add this to angle HID to get
angle HID + angle DIJ = 100+75 = 175
This matches with angle HIJ = 175
So this confirms angle HID + angle DIJ = angle HIJ which helps confirm our answers.
Alex bar and Carl are brothers Alex is the oldest and Carl is the youngest the some of the ages of the three brothers is 42 Alex his age is three more than twice Carl's age the difference between Barts in Carl's ages is seven years how old is each brother
Answer:
Alex = 19 years
Bart's = 15 years
Carl = 8 years
Step-by-step explanation:
Let us represent their ages as
Alex = x
Bart's = y
Carl = z
the sum of the ages of the three brothers is 42
x + y + z = 42
Alex his age is three more than twice Carl's age
x = 2z + 3
The difference between Barts in Carl's ages is seven years
y - z = 7
y = 7 + z
Hence: we Substitute
x + y + z = 42
2z + 3 + 7 + z + z = 42
Collect like terms
2z + z + z + 10 = 42
4z = 42 - 10
4z = 32
z = 32/4
z = 8 years
Hence, Carl = 8 years old
a) y = 7 + z
y = 7 + 8
y = 15 years.
Hence, Bart's is 15 years old
b)x = 2z + 3
x = 2(8) + 3
= 16 + 3
= 19 years
Therefore, Alex is 19 years old.

Is 2x+y=4 linear? If it is what is the slope and y intercept?
Answer: Yes, it is linear. The slope is -2
Step-by-step explanation:
move the 2x over to the other side and get y=-2x+4, the slope in a linear equation is m in the formula y=mx+b, in this case, m=-2

Aston University creates a 10 digit student number as the University enrolls each student. The first two characters must be a digit 1 through 9. The next seven characters can be anything and the last digit just can’t be the same as the ninth character (i.e. the previous digit). How many student numbers are possible?
Answer:
The number of student numbers that are possible = 729,000,000 student numbers
Step-by-step explanation:
The number of possible numbers that can take the place of the first two digits = 9 possible numbers each
The number of possible numbers that can take the place of the 3rd to the 9th digits = 10 possible numbers each
The number of possible numbers that can take the place of the 10th digits = 9 possible numbers each
The total number of possible numbers is given as follows;
9 × 9 × 10⁶ × 9 = 729000000 possible student numbers
Kyla alternates between walking and jogging on an 11-mile trail. Her walking speed is 4 mi/h, and her jogging speed is 6 mi/h. Kyla takes 2 hours to go from the beginning to the end of the trail. Write and solve an equation to find the distance Kyla walked and the distance she jogged.
Answer:
Kyla walked 2 miles and jogged 9 miles
Step-by-step explanation:
Let the distance Kyla walked be x
and the distance Kyla jogged be y
Since the trail is 11-mile long, then
x + y = 11
Now, from the question,
Her walking speed is 4 mi/h and her jogging speed is 6 mi/h
Let the time spent to walk be t₁ and the time spent to jog be t₂
From
Distance = Speed × Time
Then, the distance walked x is
x = 4 mi/h × t₁
and the distance jogged y is
y = 6 mi/h × t₂
From the question, Kyla takes 2 hours to go from the beginning to the end of the trail, that is
t₁ + t₂ = 2 hours
∴t₁ = 2 - t₂
Since
x + y = 11, then we can write that
(4 mi/h × t₁) + (6 mi/h × t₂) = 11
But t₁ = 2 - t₂
Then,
(4 mi/h × t₁) + (6 mi/h × t₂) = 11; becomes
(4 mi/h × (2 - t₂)) + (6 mi/h × t₂) = 11
8 - 4t₂ + 6t₂ = 11
2t₂ = 11 - 8
2t₂ = 3
t₂ = 3/2
t₂ = 1.5 hours
This is the time spent to jog
Then, from t₁ = 2 - t₂
t₁ = 2 - 1.5
t₁ = 0.5 hour
This is the time spent to walk
Now, For the distance Kyla walked, x
x = 4 mi/h × t₁
x = 4 mi/h × 0.5
x = 2 miles
Hence, she walked 2 miles
and for the distance Kyla jogged, y
y = 6 mi/h × t₂
y = 6 mi/h × 1.5
y = 9 miles
Hence, she jogged 9 miles

Answer:
C
Step-by-step explanation:
first, let's find the midpoint of line TR.
((x1+x2)/2, (y1+y2)/2)
(4+8)/2= x-coordinate= 6
(-4+-4)/2=y-coordinate=-4
(6,-4) is the point of A
now, use the distance formula for U (5,-6) and A (6,-4)
d= sqrt (x2-x1)^2 + (y2-y1)^2
d= sqrt (6-5)^2 + (-4-(-6))^2
d= sqrt (1+4)
d= sqrt 5
C. sqrt 5

The price when selling on installments be $822025.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.equation modelling : Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that the value of a house is $655,000 in cash, but when selling it on installments, you are charged 25.5% of its price.
Assume the price when selling on installments be $x. Then, we can write new price as -
[x] = 655000 + {25.5% of 655000}
[x] = 655000 + {25.5/100 x 655000}
[x] = 655000 + {25.5 x 6550}
[x] = 655000 + 167025
[x] = $822025
Therefore, the price when selling on installments be $822025.

some number is added to itself the result is multiplied by eight is four what is that number
Answer:
X=1/4
Step-by-step explanation:
(x+x)*8=4
(2x)*8=4
16x=4
X=4/16=1/4
Answer:
0.25
Step-by-step explanation:
First...
Assume that the number is x and make an equation.
(x + x) 8 = 4
Next...
Add.
(2x) 8 = 4
After that...
Divide.
2x = 4/8 so 2x = 1/2
Finally...
Divide more
x = 1/4 or 0.25
So your answer is 0.25.
I did double-check.
