A=pi r^2
<span>then use your rate of $4.60/m^2 and multiply that by your area. </span>
<span>A = 3.14 (.8^2) </span>
<span>Cost = 2.01 m^2 $4.60/m^2 = $9.24
So your answer would be B</span>
x=heavy equipment
y= general labor
x+y=38
x=38-y
134x + 92y=4756
134(38-y)+92y =4756
5092-134y+92y=4756
-42y = -336
y = -336/-42 = 8
x=38-8=30
check 30*134 =4020
8*92 = 736
4020+736 = 4756
8 general laborers
30 heavy equipment operators

Answer:
Q(-2, -1)
Step-by-step explanation:
P(-2, 5) is 3 units ABOVE the line y = 2. If we reflect this point in the line y = 2, we end up with a point Q(-2, -1), where the '-1' comes from subtracting 3 from 2.
Answer:
The variables can add up to each other
5b + b = 6b because the 1 is hidden in front of the b. When there is a variable without a number in front of it you assume it is one.
EX: 7h + h + h = 9h
