Answer:
Step-by-step explanation:
y = total cost and x = number of tons
y = 125x + 7500
the total cost for transporting 15 tons...sub in 15 for x
y = 125(15) + 7500
y = 1875 + 7500
y = $ 9375 <===== total cost
1) 15 = 5(x + 2)
15 = 5x + 10
15 - 10 = 5x + 10 - 10
5 = 5x
5/5 = 5x/5
1 = x
2) 5n + 34 = -21(1-7n)
5n + 34 = -21 + 147n
5n + 34 = -21 + 147n
5n - 147n + 34 = -21 + 147n - 147n
-142n + 34 = -21
-142n + 34 - 34 = -21 - 34
-142n = -55
-142n/-142 = -55/-142
n = 55/142
A: -vp + 30 < 45
Subtract 30 from both sides.
-vp < 15
Divide both sides by -v.
p > -15/v
( when dividing a negative, the < sign must be changed to >)
B. 3w - 6r = 30
Subtract 3w from both sides.
-6r = -3w + 30
Divide both sides by -6
r = (-3w + 30)/ -6
simplify the right side
r = (w - 10)/2
OR
r = (-3w/-6) + (30/-6)
r = w/2 - 5
