Two students are reading a novel. Ashley reads 10 pages per day. Carly reads 8 pages per day, but she starts
natulia [17]

Answer:

On day 20, they should both be on page 200

Step-by-step explanation:

I set the 2 equations up:

10d=8d+40 and then subtracted 8d from both sides

2d=40 and then divided both sides by 2

d=20

I then took 20 and multiplied it by 10 for Ashley (200) and then multiplied it by 8 for Carly (160) and added 40 (200)

Hope this helps!

8 1/2 by 11 inches dilated to 1 7/10 inches by 2 1/5 inches. what is the scale factor
Leni [432]
8    1/2      by      11.

Area1  =    8    1/2  ×  11

Area1 =    17 / 2  × 11 = 187/2


17/10      by     2  1/5

Area2  =    17/10  ×   11/5

Area2 =    17 / 10  × 11/5 = 187/50


Scale factor =  Area1 / Area2

                     =    187/2    ÷ 187/50

                     =    187/2  ×  50/187

                     = 25

Scale factor = 25
