Answer:
x > 4
Step-by-step explanation:
5x + 17 > 37
Subtract 17 from each side
5x + 17-17 > 37-17
5x > 20
Divide each side by 5
5x/5 > 20/5
x > 4

2n + -7 + 3(4n + -3) = 0
Reorder the terms:
2n + -7 + 3(-3 + 4n) = 0
2n + -7 + (-3 * 3 + 4n * 3) = 0
2n + -7 + (-9 + 12n) = 0
Reorder the terms:
-7 + -9 + 2n + 12n = 0
Combine like terms: -7 + -9 = -16
-16 + 2n + 12n = 0
Combine like terms: 2n + 12n = 14n
-16 + 14n = 0
Solving
-16 + 14n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '16' to each side of the equation.
-16 + 16 + 14n = 0 + 16
Combine like terms: -16 + 16 = 0
0 + 14n = 0 + 16
14n = 0 + 16
Combine like terms: 0 + 16 = 16
14n = 16
Divide each side by '14'.
n = 1.142857143
Simplifying
n = 1.142857143</span>
Y=6 when x=18, find y when x=-12
so 6/18 = y/-12
cross multiplication
(6)(-12) = (18)(y)
-72 = 18y
divide both sides by 18
-4 = y

Answer:
riley
Step-by-step explanation:
<span>$4180.56
First, determine the area of the driveway by multiplying its length by its width, so
a = 10 * 150.5 = 1505 ft^2
Now convert from ft^2 to yd^2 by dividing by 9.
1505 ft^2 / 9 ft^2/yd^2 = 167.222 yd^2
Finally, multiply by the cost per sq yd
167.222 * 25 = 4180.56</span>
