An animal shelter has $2500 in its reserve fund. The shelter charges $40 per animal placement and would like to have at least $4

Elena-2011 [213]

Answer:

Step 1

Write and solve the inequality:

2,500 + 40a ≥ 4,000, or 40a ≥ 1,500

a ≥ 37.5

Step 2

If the shelter places 30 cats and 10 dogs,

or 40 animals, that will be enough to meet

its goal, because a = 40 is a solution to the

inequality a ≥ 37.5.

The perimeter of a rectangle is 343434 units. Its width is 6.56.56, point, 5 units.

Andru [333]

This is annoying

the perimiter is 34 units
the width is 6.5 units

ok.
perimiter=2(Length+Width)
P=2(L+W)
solve for L
distribute
P=2L+2W
minus 2W
P-2W=2L
divide by 2
$\frac{P-2W}{2}=L$

given that P=34 units and W=6.5 units
$\frac{34-2(6.5)}{2}=L$

the equation would be $L=\frac{P-2W}{2}$ or $L=\frac{P}{2}-W$
