Mathematics
1 answer:
Anestetic [448]3 years ago
4 0

Explanation:

4x+3y=37

y=x-4

4x+3(x-4)=37

4x+3x-12=37

add 12 to both sides

7x=49

x=7

Now you use plug in x

4(7)+3y=37

28+3y=37

subtract 28 to both sides

3y=9

y=3

answer: x=7 and y=3

Basile [38]

Answer:

The box must be 3 inches in height

Step-by-step explanation:

In this question, we are concerned about calculating the height of the supplies box.

To be able to get the value for the volume, we need to use the mathematical formula.

Since It is a rectangular prism, the volume V = l * b * h

where l, b and h are the length, breadth and height respectively. Now , it is the measurement of the base that is l * b, hence the base area in this question is 6 * 5 = 30 inches^2

The height of the supply box is thus 90/30 = 3 inches high
