Adding the two equations will be adding similar terms to both equations. That is:
8x + (-8x) = 0
-10y + (-6y) = -16y
20 + (-4) = 16
Therefore, adding the two equations will look like -16y = 16. (Option 3)

A new youth activity center is being built in oak valley. the perimeter of the rectangular playing field is 332 yards. the length of the field is 5 yards less than double the width.
Let the width is x yards . And length is 5 yards less than double the width, so length is (2x-5) yards .
Perimeter is the sum of all sides, that is
So the width is 57 yards and length is
Answer:
Probability = 0.00621
Step-by-step explanation:
We are given;
Population mean; μ = 400
Population standard deviation; σ = 20
Raw score; x¯ = 450
the probability that the actual costs will exceed the budgeted amount will be the p-value.
Thus, let's first find the z-score after which we will find the p-value.
z = (x¯ - μ)/σ
z = (450 - 400)/20
z = 50/20
z = 2.5
From online p-value from z-score calculator attached, using z = 2.5; one tailed hypothesis; significance level of 0.05, we have;
P-value = 0.00621
