Step-by-step explanation:

Answer A: Subtract 9 from both sides

Explanation: You want to solve the x from this equation, then the first thing is to put the number that has no valiable x to the other sides, so in this equations, we want to move 9 to the right side, so we subtract 9 from both sides.

Hello there!

Write a compound inequality for this sentence: 'w' is less than 4 and greater than or equal to -8
Only use 'w' once.


W is less than four ~ 4 \ \textgreater \ w

W is greater than or equal to -8 ~ w \geq -8

If we were to put this together, it would look like:

4 \ \textgreater \  w  \geq  -8

Finding the slope using two points:

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

(-4, 3) and (5, 3)

y_{2} =3\\y_{1} =3\\x_{2} =5\\x_{1} =-4

^^^Plug these numbers into the formula for slope...

\frac{3-3}{5 - (-4)}

\frac{0}{9}

B. 0

^^^This is your slope

Hope this helped!

a vehicle uses 1 1/8 gallons of gas to travel 13 1/2 miles. at this rate how many miles can the vehicle travel per gallon of gas
elena55 [62]

Answer:

The vehicle can travel 12 miles per gallon of gas.

Step-by-step explanation:

  • The number of gallons used by a vehicle = 1 1/8 gallons

i.e.

1\frac{1}{8}=\frac{9}{8} gallons

  • The number of miles traveled by a vehicle = 13 1/2 miles

i.e.

13\frac{1}{2}=\frac{27}{2} miles

Thus,

Total Gallons =9/8 gallons

Total Distance in miles = 27/2 miles

Hence:

Unit Rate = [27/2 miles] / [9/8 gallons]

                = 12 miles per gallons  ∵ \frac{27}{2}\div \frac{9}{8}=12

   

Therefore, the vehicle can travel 12 miles per gallon of gas.
