Answer:
2 tons of dirt per hour
Step-by-step explanation:
helpful to know: 1/6 hours = 10 minutes
you can create a proportion to find unit rate by using (tons of dirt ÷ time)
we'll use 'd' to represent amount of dirt and use minutes
1/3÷10 = d/60
1/3÷10 = 1/3 × 1/10 = 1/30
we now have:
1/30 = d/60
we can cross-multiply to get:
30d = 60
d = 2
Answer:
The value of x in this equation is -4.
Step-by-step explanation:
2(4x - 6) = 4(3x - 7)
Distribute 2 to (4x - 6) and distribute 4 to (3x - 7)
8x - 12 = 12x - 28
Subtract 12x form both sides of the equation.
-4x - 12 = -28
Add 12 to both sides of equation.
-4x = 16
Divide -4 on both sides of the equation.
x = -4
The value of x is -4.
Answer:
b = 72
Step-by-step explanation:
It is a linear equation in one variable, b. Maybe you want the solution.
Multiplying the equation by 24, we get ...
9b +4b +10b = 1656
23b = 1656 . . . . collect terms
b = 72 . . . . . . . . divide by 23
