Answer:
The car that has a fuel efficiency of 40 mpg consumed 35 gallons, while the car that has a fuel efficiency of 20 mpg consumed 40 gallons.
Step-by-step explanation:
The variable a will represent the fuel consumed by the first car, and the variable b will represent the fuel consumed by the second car.
Set up the formula: a+b=75, which will represent the total gas consumption.
The formula 20a+40b=2200 will help you solve.
To solve, we will first solve for a by changing the formula from a+b=75 to b=75-a. Then you plug in the value of b to the second formula:
20a+40(75-a)=2200
20a+3000-40a=2200
3000-20a=2200
After subtracting 3000 from both sides, you are left with -20a=-800. Multiply both sides by -1 so that both sides are positive:
20a=800
a=40
Now that we know that the car with a 20 mpg fuel efficiency consumed 40 gallons that week, we can subtract 40 from 75, leaving us with 35 being the amount of gallons consumed by the car with a 40 mpg efficiency.
and mZTRB = 86. Find the mZTRI.
Answer:
m∠TRI = 43
Step-by-step explanation:
m∠TRI + m∠IRB = m∠TRB
3x - 5 + x + 27 = 86
3x + x - 5 + 27 = 86 {Combine like terms}
4x + 22 = 86 {Subtract 22 from both sides}
4x = 86 - 22
4x = 64 {Divide both sides by 4}
x = 64/4
x = 16
m∠TRI = 3x - 5
= 3*16 - 5
= 48 - 5
= 43
Answer:
Nancy's ambient locality might be having more suppliers, higher supply of Gasoline
Step-by-step explanation:
National average price of gasoline = $3.14
Stations near Nancy's home have an average price = $2.95
Gasoline price near Nancy's house is lesser than national average price level. Number of gasoline stations near her house might be more. It implies increase in its supply. This leads to competition among sellers & reduces the price level.
