Question

Which of the following expressions have a value of 180 when b= 4? Select all that apply. A. 87b - 179 + 957 : 87 B. 336 62 + 120 C D. 51b - 24 E. 11b + 187 – 2,756 : 13

Answer 1

We need to find which expression have a value of 180 when b = 4

A.

`\begin{gathered} 87\cdot b-179+(957)/(87) \\ =87\cdot4-179+(957)/(87)=180 \end{gathered}`

B.

`(33\cdot b)/(12)=(33\cdot4)/(12)=11`

C.

`b^2+120=4^2+120=16+120=136`

D.

`51\cdot b-24=5\cdot4-24=-4`

E.

`\begin{gathered} 11\cdot b+187-(2756)/(13) \\ =11\cdot4+187-(2756)/(13) \\ =19 \end{gathered}`

So, the answer is option A
