Question

Plllssss help Select all equations that are also equivalent to0.6 + 15b + 4= 25.6 ( choose all the ones down below the equal the top)A . 15b+4 = 25.6B .15b+4=25 C. 3(0.6+ 15b +4) = 76.8 D. 15b = 25.6E. 15b= 21

Answer 1

The given equation is

`0.6+15b+4=25.6`

If we subtract 0.6 on each side, we get

`\begin{gathered} 0.6+15b+4-0.6=25.6-0.6 \\ 15b+4=25 \end{gathered}`

Therefore, the given expression is equivalent to B.

If we multiply the given equation with 3, we get

`\begin{gathered} 3\cdot(0.6+15b+4)=25.6\cdot3 \\ 3(0.6+15b+4)=76.8 \end{gathered}`

Therefore, the given expression is equivalent to C.

At last, if we subtract 0.6 and 4 on each side, we get

`\begin{gathered} 0.6+15b+4-0.6-4=25.6-0.6-4 \\ 15b=21 \end{gathered}`

Therefore, the given expression is equivalent to E.

The right answers are B, C, and E.
