Awoman wants to make a 4 inch wide copy of a drawing that is 5 inch wide. on the photo copier, what percent setting should she use to make a copy this size
a 5%
b 80%
c 90%
d 125%

B 80 %

Step-by-step explanation:

She wants to reduce the size of the drawing, so the setting should be a proper fraction.

                                                                Setting = 4/5

Multiply numerator and denominator by 20     = 80/100

Convert to percent                                             = 80 %

The setting should be 80 %.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
