Answer:
x = -5/P
Explanation:
We are given
Px + 17 = 12
Subtract 17 on both sides using the Subtraction Property of Equality
Px = -5
Divide both sides by P to isolate *x* by itself using the Division Property of Equality
x = -5/P
Answer:32
Step-by-step explanation:
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.
Area=legnth times width
width=1/5
area=1/5 times width
area=4
4=1/5 times legth
multiply both sides by 5/1 to clear fraction (since 1/5 times 5/1=5/5=1)
remember ou can do anything to an equaiton as long as you do it to both sides
20=1 times legnth
20=legnth
answer is legnth==20 m
Alternate interior angles.
