Answer:
x = - 6
Step-by-step explanation:
Given
4(x + 6) - 2x = 12 ← distribute and simplify left side
4x + 24 - 2x = 12
2x + 24 = 12 ( subtract 24 from both sides )
2x = - 12 ( divide both sides by 2 )
x = - 6
Answer:
y=0.8x+2.1
x= 12 miles
Step-by-step explanation:
Using the standard charge of 0.8 per mile and a fixed charge of $2.1. Let x represent the miles covered then the expression for coat at any given mile will be y=0.8x+2.1
Substituting $11.7 for y then we can find the valje of x as 11.7=0.8x+2.1
0.8x=11.7-2.1=9.6
X=9.6/0.8=12 miles
The formula is V= l × w × h or length times width times height.
V= 45×25×60 so the answer is 67,500 but make sure you put units in your answer!
Hope this helps!
