Option m = 17
y = total cost of the service
m = number of miles run
y = 1.25 + 0.75 m
Equal the cost to the amount available by Henri
14 = 1.25 + 0.75m
Solve for m
m = (14 - 1.25)/0.75 = 12.75 / 0.75 = 17 miles.
Answer:
B
Step-by-step explanation:
52.78×6.5%=3.43
52.78×18%=9.50
52.78+3.43+9.50=65.71
Answer:
2.33 kg
Step-by-step explanation:
If the baker needs to use 2.327 kilograms of blueberries, we are going to subtract the amount of the packages to the amount he needs and we'll see which is the smallest number.
In the case of 2.3, 2.327 - 2.3 = .027
In the case of 2.42, 2.327 - 2.42 = -0.09
In the case of 2.33, 2.327 - 2.33 = -0.003
In the case of 2.4, 2.327 - 2.4 = -0.07
Therefore, the closest amount to 2.327 is the 2.33 package.
They are simple linear equations with one unknown, lets tackle them, one step at the time solving for the unknown:
4x - 2(x - 5) = x + 13
4x - 2x + 10 = x + 13
2x + 10 = x + 13
2x - x = 13 - 10
x = 3
that is the solution.
3(6 - x) - 4 = 5x + 2(7x + 3)
18 - 3x - 4 = 5x + 14x + 6
14 - 3x = 19x + 6
14 - 6 = 19x + 3x
8 = 22x
x = 8/22 = 4/11
