9x + 8y = ?

Substitute the value for x in:

Substitute the value for y in:

Multiply:

9 * 4 = 36

8 * -5 = -40

9x + 8y = 36 - 40 = -4

Alex's friend Pablo comes up with an exact equation to find out how many bags he needs. Use his equation

Bezzdna [24]

Answer:

8.5 bags are needed.

Step-by-step explanation:

Given : Number of bags needed $B=x(2x+7)+3(2x+7)+(x+4)$

$(2x + 7) = 4$

To Find : how many bags he needs?

Solution :

$(2x + 7) = 4$

$2x=-3$

$x=-\frac{3}{2}$

Now we are given that Number of bags needed $B=x(2x+7)+3(2x+7)+(x+4)$

Substitute the value of x

$B=(\frac{-3}{2})(2(\frac{-3}{2})+7)+3(2(\frac{-3}{2})+7)+((\frac{-3}{2})+4)$

$B=8.5$

Hence 8.5 bags are needed.
