Step-by-step explanation:
first, distribute 7 to 6m (this means 7 • 6m)
7 • 6m = 42m
then distribute 7 to 7 (which is 7 • 7)
7 • 7 = 49
your simplified expression is 42m + 49. i hope this helps! have a great day <3
At Pizza Pi, 12% of the pizzas made last week had extra cheese. If 6 pizzas had extra cheese, how many pizzas in all were made last week?
Answer:
50? maybe
Step-by-step explanation:
since half of the percentage was made it would also fall in for the other 88%.
im not 100% sure tho
The total number of pizzas is given as 50.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
The percent value of pizzas having extra cheese is given as 12%.
Suppose the pizzas made last week be x.
Then, as per the question the following equation can be written as,
⇒ 12% × x = 6
⇒ 12/100x = 6
⇒ x = 50
Hence, the number of pizzas that were made last week is given as 50.

3.) 4(m + 5) + 42, (m = -2)
Answer:
54
Step-by-step explanation:
The variable m equals -2, so what you would do is plug it into the equation.
4(-2+5)+42
Next you would distribute the 4 into -2 & 5.
(-8+20) + 42
Add what's in the parenthesis.
12 + 42
Once you add that you will be left with your answer which is 54.

determine if JK and LM are parallel, perpendicular,or neither . HELP AND PLS SHOW WORK !!
Answer:
1) not parallel
2)not parallel
Step-by-step explanation:
fist one intersect already
and second one will eventually intersect
Answer:
1 - Perpendicular.
2 - Neither.
Step-by-step explanation:
Use the slop formula to find the slope of the two sides.
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]JK = \frac{4-9}{7-1} = \frac{-5}{6}[/tex]
[tex]LM = \frac{1-13}{-2-8} = \frac{-12}{-10} = \frac{6}{5}[/tex]
Perpendicular - because a line that is perpendicular to another must have a slope that is the negative reciprocal of the first line.
[tex]JK = \frac{6-(-5)}{2-13} = \frac{11}{-11} = 1[/tex]
[tex]LM = \frac{-2-(-5)}{-4-(-1)} = \frac{3}{-3} = -1[/tex]
Not Parallel. Nor perpendicular.

Answer:
95
Step-by-step explanation:
We have the expression q over 19 = 5 and are asked to solve for q.
We have a dillemma here, q is in a fraction, to solve, all we need to do is get rid of this fraction. Since 19 is the denominator, we can multiply it by both sides :
[tex]\frac{q}{19} = 5[/tex]
19 * 5
95
Therefore :
q = 95
The hypotenuse of a right angle triangle is 4 metres. If its other sides are equal find the length of each side.
Answer:
[tex] \sqrt{8} [/tex]
or
[tex]2 \sqrt{2} [/tex]
Step-by-step explanation:
Since the legs are equal this is a 45-45-90 triangle.
The ratio of side length for a 45 45 90 triangle
[tex](1)(1)( \sqrt{2} )[/tex]
where 1 is the legs length and sqr root of 2 is the length of the hypotenuse.
Since we are trying to find the length of the legs side we can set up a proportion.
We know the hypotenuse is 4 so our proportion looks like
[tex] \frac{1}{x} = \frac{1}{x} = \frac{ \sqrt{2} }{4} [/tex]
Let see how far sqr root of 2 goes into 4.
[tex] \sqrt{2} \times x = 4[/tex]
[tex] \sqrt{2} \times x = \sqrt{16} [/tex]
[tex]x = \sqrt{8} [/tex]
so that means the answer for the legs length is
[tex] \sqrt{8} [/tex]
or
[tex]2 \sqrt{2} [/tex]
Answer:
Step-by-step explanation:
hello :
use phtagor - rule: let x the length of each side
x² +x² =4²
2x² =16
x² = 8
x = √8
but : 8 = 4×2 = 2²×2
x = √(2²×2) = √2²× √2 =2√2 ...... √2² =2
x = 2√2 metres.
Roberto can lift 103.5 pounds. That is .9 times the amount his friend Vance can lift. Can Vance lift more or less than 103.5 pounds?
Answer:
Step-by-step explanation:
Vance can lift 0.9×103.5 pounds.
0.9 < 1, so you know that
0.9×103.5 < 103.5
Two supplementary angles are in the ratio of 5 to 7. Find positive difference of the measure of the two angles. Do the same problem, only do it for complementary angles instead of supplementary angles.
Answer:
30° is the difference if they are supplement
15° is the difference if they are complementary
Step-by-step explanation:
Let 5x = the measure of the smaller angle
and 7x = the measure of the larger angle
If they are supplementary, then 5x + 7x = 180
12x = 180
x = 15
5x = 5(15) = 75 = the measure of the smaller angle
7x = 7(15) = 105 = the measure of the larger angle
105 - 75 = 30 = difference of the measures
Now, if they are complementary, then 5x + 7x = 90
12x = 90
x = 7.5
5x = 7(7.5) = 37.5 = the measure of the smaller angle
7x = 7(7.5) = 52.5 = the measure of the larger angle
52.5 - 37.5 = 15 = difference of the measures

Two siblings' ages have a sum of 64 years. The older sibling was born 6 years before their young sibling.
Write a system of 2 equations. Solve the system using substitution. Report your answer in the form of (older, younger).
Hi!
So we have to make a system of equations here.
Let sibling 1 be O and sibling 2 be Y (for older and younger)
So:
O + Y = 64
O = 64 - Y
(Either one works)
The older sibling is 6 years older.
O = Y + 6
Make everything in terms of Y.
64 - Y = Y + 6
Same to both:
58 = 2y
2y = 58
Divide by 2 on both sides:
y = 29
Since the older sibling is 6 years older:
29 + 6 = 35
Y = 29
O = 35

What is the slope-intercept equation of the line below?
Answer:
D. y = 2x -3
Step-by-step explanation:
The equation of a line in slope-intercept form is
y = mx + b
We need to find m, the slope, and b, the y-intercept.
We can find those two numbers from the graph.
We look in the graph and see that the y-intercept, b, is -3.
Now we have y = mx - 3.
Now we look for the slope. Start at (0, -2). We need to go vertically and horizontally to the next point that is easy to read. We see that point (1, -1) is on a grid intersection making it easy to read, so we will use that point.
Go up 2 units. That is a rise of positive 2. Now go right 1 unit. That is a run of positive 1.
slope = rise/run = 2/1 = 2
m = 2, so now we have
y = 2x - 3
Answer: D. y = 2x -3

In a supermarket, bottles of lemonade are on a buy one get one half price offer.
The normal price of lemonade is 76p.
How much would it cost to get exactly three bottles of lemonade using this offer?
Answer:
114p
Step-by-step explanation:
I did the math, I really hope it's correct
The cost to get exactly three bottles of lemonade using the offer will be [tex]190p[/tex] .
What is expression ?Expressions is a finite combination of symbols that is well-formed according to rules that depend on the context.
We have,
Normal price of bottle [tex]=76p[/tex]
And,
Offer is buy one get one half price.
So,
According to the question,
Normal price of one bottle [tex]=76p[/tex]
Half price of one bottle [tex]=\frac{76p}{2}=38p[/tex]
So,
Price of three bottles [tex]=76*2+38[/tex]
[tex]=190p[/tex]
So, Price of three bottles is [tex]190p[/tex] .
Hence, we can say that the cost to get exactly three bottles of lemonade using the offer will be [tex]190p[/tex] .

A clothing store sells clothing for 2 times the wholesale plus $10. The store sells a pair of pants to customers for $48. How much did the store pay wholesalefor the pants?
Answer:
19$
Step-by-step explanation:
Let w represent the wholesale cost of the pants, or the price paid by the store
2w + 10 = 48 Subtract 10 from both sides.
2w = 38 Divide both sides by 2.
w = 19
