A rectangle has the sides: 7cm and 3cm. A square has the same perimeter as the rectangle. What is the side length if the square

5

Step-by-step explanation:

Perimeter of the rectangle: 3+7+3+7=20

Square perimeter is same as rectangle, so square perimeter is also 20.

Side length is 20/4, which is 5

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
