Step-by-step explanation:

EF = 4x - 15

FG = 3x - 7

EG = EF + FG = 20

so,

4x - 15 + 3x - 7 = 20

7x - 22 = 20

7x = 42

x = 6

EF = 4×6 - 15 = 9

FG = 3×6 - 7 = 11

An online music store offers 5 downloads for $6.25.Another online music store offers 12 downloads for $17.40.Which store offers
Anon25 [30]
Well, what you have to do is find the unit rate for each one of those prices and how you do that is by dividing each price by the downloads

so $6.25 divided by 5= $1.25

and then $17.40 divided by 12= $1.45


so that means the one with $6.25/5 downloads has a better deal!

Linda and Colleen both leave the library at the same time, but in opposite direction. If Colleen travels 8mph faster than Linda
pshichka [43]
X - Linda's speed
(x+8 )- Colleen's speed

8x - Linda's distance for 8 h
8(x+8) = 8x+64  - Colleen's distance for 8 h

8x + 8x + 64 = 176 - distance between Colleen and Linda after 8 h


8x + 8x + 64 = 176 
16x +64 = 176
16x = 176 - 64
16x = 112
x= 7 mph Linda's speed
x+8
= 7+8 = 15 mph Colleen's speed
