4a+3=40
Subtract 3 to both sides because you're inversing operation
4a=37
Divide both sides by 4
A=9.25
Hope it works :)
Answer:
10 units.
Step-by-step explanation:
Given:
<u>Formula:</u>

Substitute the length, width, and the volume of the prism in the formula

Divide 25 × 10 to both sides of the equation to isolate "Height"


Simplify the left hand side of the equation
![\implies \dfrac{{25 \times 10 \times 10}}{25 \times 10} = \text{Height} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [2500 =25 \times 10 \times 10]](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B%7B25%20%5Ctimes%2010%20%5Ctimes%2010%7D%7D%7B25%20%5Ctimes%2010%7D%20%20%3D%20%5Ctext%7BHeight%7D%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5B2500%20%3D25%20%5Ctimes%2010%20%5Ctimes%2010%5D)

Therefore, the measure of the height is 10 units.
5) Lets use x for the unknown middle side. Since all the sides have to equal to perimeter, we can set everything equal 43.
(x-3)+x+(2x-2)=43
That would be your equation.
6) Knowing what we know from the previous problem, we can set the equation to 27.
(x-3)+x+4(x-3)=27 (we can plug in x-3 to represent the first side)
7) Since all the sides have to equal to perimeter, we can set everything equal 25.
a=2b-2
c=b+3
(2b-2)+b+(b+3)=25
Answer:
x = -15
Step-by-step explanation:
-24 + 15 - 6 = x
-9 - 6 = x
-15 = x
Answer:
Step-by-step explanation:
14.88 + x = 17.05
x = 17.05 - 14.88
x = 2.17
