How do you write and solve equation with an unknown number?

8 0

You have to isolate the variable using inverse operations in order to get it alone. Example: x+3=5
Subtract 3 on both sides since you are adding 3, and subtraction is the opposite of addition.
x=2 is your answer. If you check and plug it in, you will see that it is a correct equation.

Vedmedyk [2.9K]

Any time the car is driving, the amount of gas is decreasing.
The only time the amount of gas can increase is the short time when
the car is parked at the gas station and gas is being poured into it.

Amanda drover towards the shop, stopped and got gas, then
drove some more. So the amount of gas decreases for a while,
then increases for a short time, then decreases again.

The middle graph is the one doing that.

The length of a rectangular poster is 2 more inches than three times its width. The area of the poster is 33 square inches. Solv

laiz [17]

Answer:

Step-by-step explanation:

Area of the rectangle = 33 inches sq

Area of a rectangle (formula) = l*b

let the width be x

length = 2 inches + 3x = 2+3x

Area of the rectangle = l*b = 2+3x + x

33 inches sq = 2+3x + x

33 in sq = 2+4x

33/2 = 4x

16.5/4 = x

x = 4.125

width= 4.125 inches

length = 2+3x = 2+3(4.125) = 14.375

(unless your poster is 32 sq inches and you made a mistake, just replace 33 with 32 and solve it)
