The blanks are weird. I don't understand them!
Answer:
x = 19.5
Step-by-step explanation:

<em>cross multiply</em>
-3(26) = 4(x)
<em>open the parenthesis</em>
-78 = 4x
<em>divide both sides of the equation by 4</em>
-78/4 = x
-19.5 = x
Answer:
Step-by-step explanation:
Given the total cost of the building expressed as;
C = 4550F + 37.5
C is the total cost
F is the length of the fence
Given
C = $352.50
Required
The length of the fence F
Substitute into the formula;
C = 4550F + 37.5
$352.50 = 4550F + 37.5
4550F = 352.50 - 36.5
4550F = 316
F = 316/4550
F = 0.0695 feet
hence 0.0695 feet of fence will cost $352.50
Answer:
x=15
Step-by-step explanation:
3/5=9/x
Hey, you have to put the number in replacement of the letter you know? Ex #1.) 3x + y. x=3 y=5
So you would rewrite the equation as
3•3 + 5 which is 14. i hope this helped..
