Step-by-step explanation: look so if you have

shcool A its 8v+4b=12

and

School B: 12v+4b= 16

since both classes used 4 busses we can use elimination by subtracting the A class Equation from the b class equation to solve from v for its value Then, use either equation and the now found value for v to solve for b.

You should find part of the process to be

12v+4b-(8v+4b)=12-16 which shows the van holds only a few people even before continuing the solution.

Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project.in feet how much board was left?

$\frac{5}{8} \text{ feet board is left }$

Solution:

Given that, Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project

To find: Board that was left

From given,

$\text{Total length of board } =\frac{7}{8} \text{ feet }$

$\text{Foot that was cut off } = \frac{1}{4} \text{ feet }$

Remaining feet of board is found by finding the difference between total length of board and foot that was cut off

$\text{Reamining board } = \text{Total length of board - feet of board that was cut off}\\$

Substituting the values we get,

$\text{Remaining board } = \frac{7}{8} - \frac{1}{4}\\\\\text{Remaining board } =\frac{7}{8} - \frac{1 \times 2}{4 \times 2}\\\\\text{Remaining board } =\frac{7}{8} -\frac{2}{8} = \frac{7-2}{8}\\\\\text{Remaining board } =\frac{5}{8}$
