Answer:
x = -20
Step-by-step explanation:
2(x+7) 2x + 20 - 2 = x+4 2x + 8
2x+14 + 2x + 20 - 2 = x + 4 + 2x + 8
4x +32 = 3x + 12
x = -20
Answer:
B.the size of the figures change
Step-by-step explanation:
Answer:
2.75x + 114 = 320.25
x = $75
Step-by-step explanation:
2.75x + 114 = 320.25
number of hours of labor (2.75) times the cost per hour of labor (x) + cost of parts (114) = total cost (320.25)
2.75x + 114 = 320.25
subtract 114 from both sides
2.75x = 206.25
divide both sides by 2.75
x = 75
------------------------
check the math:
2.75(75) = 114 = 206.25 + 114 = 320.25
