Answer: A. 5x+x+18 = 180
Step-by-step explanation:
For B you need to find the value of x first.
5x + x + 18 = 180 is your equation.
Combine like terms: 5x+x = 6x
Equation should now look like this
6x + 18 = 180
Subtract 18 to both sides 180-18 = 162
Do 162/6 = 27
X = 27
WE ARE NOT DONE!!!!!
1. 5(27) = 135
2. 27+18 = 45
Angle 1 = 135
Angle 2 = 45
Answer:
Z value for the first pump = -0.68
Z value for the second pump = 0.45
Step-by-step explanation:
Data provided in the question:
Mean labor cost to repair a heat pump = $90
Standard deviation = $22
Labor cost for the first, X₁ = $75
Labor cost for the Second, X₂ = $100
Now,
Z value for the first pump = [X₁ - Mean] ÷ Standard deviation
thus,
Z value for the first pump = [ $75 - $90] ÷ $22
= - 0.68
Z value for the second pump = [X₁ - Mean] ÷ Standard deviation
thus,
Z value for the second pump = [ $100 - $90] ÷ $22
= 0.45
Simplify the expression
-10
Hope this helps! :)

Step-by-step explanation:
x+y=5
x^3+y^3+15xy-125
(x+y)(x^2-xy+y^2)+15xy-125
5(x^2-xy+y^2)+15xy-125
5x^2+5y^2-5xy+15xy-125
5x^2+5y^2+10xy-125
5[x^2+2xy+y^2]-125
5(x+y)^2-125
5(5)^2-125
125-125
