Set up the equation 88+7.25h=169. Now that we have the equation and the only variable to solve is h, we will begin the algebra.
1. Using the Subtraction Property of Equality, subtract 88 from both sides to get the equation 7.25h = 81
2. Now use the Division Property of Equality to divide both sides of the equation by 7.25. You should then get h = 11.1724...
Now assuming he is getting paid by the hour, the number of hours he needs to work to get the skateboard is 12.
A. set the top equation as x=something. you can do this by transforming functions.
answer x=2y-8
Then you substitute 2y-8 for x in the bottom problem. 4(2y-8) - 8y= 10.
Solve for y. you will get a false equation. -32=10. Proved.
B. we know that the lines are parallel. if the line don't have a solution that means that they don't intersect. that means they must be parallel because parallel lines never intersect.
Answer:
24 customers will not use coupons.
Step-by-step explanation:
Number of customers who use coupons = 9
Number of customers who don't use coupons = x
Ratio of customers who use coupons to customers who don't use coupons = 6:16



24 customers will not use coupons.
(-3/4m) -(1/2)=2+(1/4m)
-(1/2)=2+m
m= -3/2
