Answer:
x = 1
Step-by-step explanation:
-8(1+4x)+7x=-25-8x (Given)
-8 + -32x + 7x = -25 - 8x (Distribute)\
-8 + -25x = -25 - 8x (Combine like terms)
-17x = -17 (Move variables(x) to the left and constants to the right)
x = 1 (Divide) (the answer is positive because when you divide a negative number by a negative number it turns positive)
are -15x and -15 like or unlike
are 1/4c and -9c like or unlike
are 6y and 6x like or unlike
are 30 and -25 like or unlike

Emma says the ratio of pools open on weekends to the total number of pools is 6:11.
Which student is correct? Explain.
Answer:George

George is correct they said that the ratio of pools open on weekends to the total number of pools is 6:16.
What are ratios and proportions?A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other. For example, if there is one boy and three girls, the ratio could be written as 1: 3. (for every one boy there are 3 girls) One-quarter are boys and three-quarters are girls.
Given that In a city, there are 16 swimming pools. On weekends, 6 of the pools are open.
George says the ratio of pools open on weekends to the total number of pools is 6:16.
Emma says the ratio of pools open on weekends to the total number of pools is 6:11.

Step-by-step explanation:
Do the inverse operation.
5 + 7/8 = 5 7/8
Or, do this instead!
Add 7/8 to both sides of the equation. On the side before the equal sign, -78 and +78 cancel out, leaving m all by itself. Bring down the equals sign and we have m = 5 7/8!

Question 1
A truck driver drove 48 miles in 45 minutes. At this rate, how many miles can the truck driver drive in one hour?
__ miles in one hour
pls no links ty
The truck driver can drive 64 miles in one hour.
Distance covered by the truck driver in 45 minutes = 48 miles
Distance covered by the truck driver in 1 minute = [tex]\frac{48}{45}[/tex]
= 1.066 miles
Distance covered by the truck driver in 1 hour i.e. 60 minutes = 60 × 1.066
= 63.96
≈ 64 miles
Therefore, the distance covered by the truck driver in 1 hour is 64 miles.
