Answer:
23 boxes of toys are being stored.
Step-by-step explanation:
There is a fixed cost of $1200 a month for rent and a variable cost of $5 per box of toys that are stored
This means that for x boxes of toys stored, the total cost is of:
![C(x) = 1200 + 5x](https://tex.z-dn.net/?f=C%28x%29%20%3D%201200%20%2B%205x)
If the total cost for this month was $1315, how many boxes of toys are being stored?
This is
for which
. So
![C(x) = 1200 + 5x](https://tex.z-dn.net/?f=C%28x%29%20%3D%201200%20%2B%205x)
![1315 = 1200 + 5x](https://tex.z-dn.net/?f=1315%20%3D%201200%20%2B%205x)
![5x = 115](https://tex.z-dn.net/?f=5x%20%3D%20115)
![x = \frac{115}{5}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B115%7D%7B5%7D)
![x = 23](https://tex.z-dn.net/?f=x%20%3D%2023)
23 boxes of toys are being stored.

Answer:This is litr=erally middle school math its so easy
Step-by-step explanation:
Answer:
x=2, y=4. (2, 4).
Step-by-step explanation:
x+y=6
3x-2y=-2
---------------
y=6-x
3x-2(6-x)=-2
3x-12+2x=-2
5x-12=-2
5x=-2+12
5x=10
x=10/5
x=2
y=6-(2)=6-2=4
h(t) = -16t^2 + vt + 5
h(3) = 131 ft
h(3) = -16(3)^2 + 3v + 5 = 131
3v = 270
v = 90 ft/s
