There are 728 vehicles in town. 432 of them are in parking lots. x of them are not in a parking lot. Solve for x.
The amount of cars in town parking lots = 432
x vehicles are not in a parking lot that is in town, and a total of 728 vehicles are in town.
432 + x = 728 (starting equation) -432 -432 (Subtract 432 from both sides)x = 296
There are 296 vehicles in town that are not in parking lots.
Buster is 14 years old, and he has gotten 28 cavities. so far. Each year, Buster has gotten the same number of cavities. That number is x.
We can represent this situation with an equation. 14x = 28Now we divide by 14 on both sites. 14x/14 = 28/14 . That gives us x = 2. I get 2 cavities every year.
Today x people came to school, which is 19 more people than they did yesterday. 504 people came to school yesterday.
We can represent this as x - 19 = 504
To solve for x, we must add 19 on both sides.
We get x = 523. 523 people came to school today!
There was x face masks at a pharmacy on Sunday. The next day, the pharmacy sold a lot of face masks that day and did not receive any new ones, so the pharmacy had 10, or x/10 face masks. How many face masks did the pharmacy have on Sunday?
x/10 = 10 (starting equation) x/10 * 10 = 10*10 (Multiply both sides by 10)That simplifies to x=100
