8 x (5 x 2 + 3)= 8 x ( 15 + 3) = 8 x 13 = 104.
Hope I helped!(:
5 7/8 is 47/8
Because,
You multiply 5 and 8 and then add 7, then you keep the denominator.
Answer:
6 < x ≤ 20
Step-by-step explanation:
First, let's use the points (0, 50) and (20, 0) to find the equation of the line.
m = Δy / Δx
m = (0 − 50) / (20 − 0)
m = -2.5
y = -2.5x + 50
Now find the time when y = 35.
35 = -2.5x + 50
-15 = -2.5x
x = 6
So there is less than 35 gallons in the barrel when 6 < x ≤ 20.
