Answer:
10x-15
Step-by-step explanation:
First, do Abbey. Abbey= 5 hrs less than 3 Emily.
Nathan spends twice as much as Abbey. Then you get 3x (Emily is x) -5 +x (for Emily) +6x - 10 (for Nathan. Add those. You get 3x+x+6x-5-10. I hope this is correct.

Answer:
y is 25.45
Step-by-step explanation:
y=1.65x+2.35 insert the unknown x
y=1.65(14)+2.35 open brackets by multiplication
y=23.1+2.35
y=25.45
Use rise over run to find slope. If you don't know what that is, its y2-y1/x2-x1. Y2 is 125, Y1 is 25, X2 is 5, and X1 is 1. You then plug the numbers in, 125-25=100. 5-1=4. then you divide 100/4, in which you get 25. So you times 25 by 3, getting 75.
