Answer:
x = 28
Step-by-step explanation:
7(8 - x) = -5x
56 - 7x = -5x Distribute 7 to the parenthesis
56 = 2x Add -7x to both sides
28 = x Divide 2 to both sides

Answer:
1 cm to 7.5 m
Step-by-step explanation:
A drawing scale is a ratio of two numbers.
The given scale, 4 cm to 30 m, can be written as a ratio in the form of a fraction,
(4 cm)/(30 m)
Since it can be written as a fraction, it can also be reduced like a fraction.
The problem wants the number of cm to be 1 cm. We have 4 cm.
Divide the numerator and denominator by 4.
(1 cm)/(7.5 m)
Now write it in the format the problem asks.
1 cm to 7.5 m
Answer:
80 minutes
Step-by-step explanation:
She runs an 8 minute mile (which you can do by dividing 24/3), then how long will it take her to run 10 miles?
All you have to do from there is multiply 8x10, which gives you 80.
It'll take 80 minutes of 1:20 hours
D the slope for function A one is -2 and the slope for function B is 4
