Average rate of change is the slope of two coordinate points or values.
Therefore,
Given values are :
(1960,668) and (1970,760)
Slope = (760 - 668)/(1970 - 1960)
Slope = 92/10
Rate of change will be 9.2 gallons/passenger
Answer: 148 lbs
first you do 4+3.5+2=9.5 then you do 9.5-4.5=5 so then you do 153-5 to get your answer 148 lbs
i hope this helps :)
We can write this as an equation: [(x - 9) + (x - 9)] + (x + x) = 70
Steps to solve:
[(x - 9) + (x - 9)] + (x + x) = 70
Combine like terms:
(x + x + x + x) + (-9 - 9) = 70
Simplify.
4x - 18 = 70
Add 18 to both sides.
4x - 18 + 18 = 70 + 18
Simplify.
4x = 88
Divide 4 to both sides.
4x/4 = 88/4
Simplify.
x = 22

Answer:
x=-9, y=-6. (-9, -6).
Step-by-step explanation:
4x-5y=-6
-6x+7y=12
----------------
6(4x-5y)=6(-6)
4(-6x+7y)=4(12)
-----------------------
24x-30y=-36
-24x+28y=48
-----------------------
-2y=12
y=12/-2
y=-6
4x-5(-6)=-6
4x+30=-6
4x=-6-30
4x=-36
x=-36/4
x=-9
