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

A.

[tex]\begin{gathered} 87\cdot b-179+\frac{957}{87} \\ =87\cdot4-179+\frac{957}{87}=180 \end{gathered}[/tex]

B.

[tex]\frac{33\cdot b}{12}=\frac{33\cdot4}{12}=11[/tex]

C.

[tex]b^2+120=4^2+120=16+120=136[/tex]

D.

[tex]51\cdot b-24=5\cdot4-24=-4[/tex]

E.

[tex]\begin{gathered} 11\cdot b+187-\frac{2756}{13} \\ =11\cdot4+187-\frac{2756}{13} \\ =19 \end{gathered}[/tex]

So, the answer is option A
