Answer: x=9

Step-by-step explanation:

Given the equation x-2=7, you need solve for the variable "x", to do this, you need to remember the Addition property of equality, which states that:

If\ a=b,\ then\ a+c=b+c

rjkz [21]

Answer:

Sebastian spent $40.40 at the gas station.

Step-by-step explanation:

First let's find how much the gas cost.

So it's $2.91 a gallon, and Sebastian fills 10 gallons of gas, so we multiply.

10 * 2.91 = $29.10

Then we add on the $11.40 from the granola bars and the box of tissues.

$29.10 + $11.40 = $40.50

So the final price should be $40.40. Sebastian spent $40.40 at the gas station.
