Which of the following values of m will result in a true statement when substituted into the given equation? m – 1.9 = 2.2

A. m = 2.8
B. m = 3.8
C. m = 4.1
D. m = 4.9

a² + b²= c²

24² + 7² = c²

c= 25

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
