Step-by-step explanation:
Answer:
C and D
Equation: you would multiply the price per driveway by the number of driveways which would be 6 + x ( 6 on Saturday and x on Sunday)
The equation would be 12(6 + x) = 144
Solve for x:
12(6 + x) = 144
Simplify:
72 + 12x = 144
Subtract 72 from both sides
12x = 72
Divide both sides by 12
X = 6
4.875 × 105
(scientific notation)
= 4.875e5
(scientific e notation)
= 487.5 × 103
(engineering notation)
(thousand; prefix kilo- (k))
