Question

2) The sum of two times an integer and 64 is less than 100. What is the greatest number that integer can be?

(A.CED.1)
a. 0
b. 12
c. 20
d. 17

Answer 1

Let the integer be X

2x+64=99

2x= 99-64

2x= 34

x=34÷2

X= 17.5

Answer 2

Answer is b 12 as:

Let the integer be x

2x + 64 = >100 = 100- x
2x+x = 100 - 64 = 36
3x = 36
x = 36/3 = 12

Thus, the answer is b) 12
