This fence has three posts, equally spaced .each post is 15 centimetres wide. the length of the fence is 153 centimetres. calculate the length of one gap between two posts

(3posts x 15 centimeters) + 2gaps x Xcentimeters = 153centimeters

45 + 2X = 153

2X = 108

X = 54 centimeters

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

1/3 + 1/5 = 8/15.

step-by-step explanation:
