Perimeter is all sides added up.
So, we know the width is 19ft and the length is x feet. We also know that the perimeter is 87 feet.
What we can do is make an equation to solve for x.
2x + 2(19) = 87
First, multiply 2 and 19.
2 x 19 = 38
2x + 38 = 87
Next, subtract 38 from both sides to move 38.
2x = 87 - 38
2x = 49
Lastly, divide both sides by 2 to get the value of x.
x = 49/2
x = 24.5
Thus, the length of the rectangle is 24.5ft
We can plug it into our equation to check if its correct.
2(24.5) + 2(19) = 87
24.5 x 2 = 49
2 x 19 = 38
49 + 38 = 87
Answer:
The plumber worked for 1.5 hours
Step-by-step explanation:
y = 130 + 56x
Substitute 214 for y in the equation
214 = 130 + 56x
-130 -130 Subtract 130 from both sides
84 = 56x Divide both sides by 56
1.5 = x
