Gabriel is getting new flooring in his kitchen. the kitchen is 10 ft. x 10 ft. the tiles he wants to use are each 2ft x 2 ft. how many tiles will he need?

Multiply 10 by 10 to get 100 and 2 by 2 to get 4. The area 1 tile will take up is 4 square feet and the kitchen is 100 square feet. Divide 100 by 4 to get 25 tiles as the answer.

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
