Answer:

Sara drives 22.5 miles per gallon and 299.25 miles in 13.3 gallons of gas.

Step-by-step explanation:

Sara drives 72 miles on 3.2 gallons of gas and we have to calculate how many miles per gallon she can drive.

By unitary method

∵ 3.2 gallons of gas is used to drive = 72 miles

∴ 1  gallon of gas is used to drive = 72÷3.2 miles

                                                       = 22.5 miles

∴ 13.3 gallons of gas is used to drive = 13.3×22.5 = 299.25 miles

Therefore Sara drives 22.5 miles per gallon of gas and on 13.3 gallons of gas she drives 299.25 miles.

What are different solutions of 1x +2y = 12
miv72 [106K]

Answer:

x=12, y=6

Step-by-step explanation:

Very simple!

Just substitute 0 for y and solve for x!

x+2(0)=12 (anything times 0 equals 0!)

x=12

Now you can do the same thing but substitute 0 for x!

0+2y=12

y=6

Hope this helps!

Which graph shows the solution to the system of linear inequalities?
tangare [24]

Answer:

  • See below

Step-by-step explanation:

<u>Given system:</u>

  • y ≥ 2x + 1
  • y ≤ 2x – 2

The solution is the common area shaded by the inequalities.

The lines are parallel because of same slope.

Both lines are solid because of equal sign in both inequalities.

The first inequality has a y-intercept of 1 and shaded area is to the left of the line since the value of y is greater as x increases.

The second inequality has a y-intercept of -2 and shaded area is to the right of the line since the value of y is greater as x increases.

The matching graph is the second picture (or attached below) and there is no solution.
