To solve this problem, we first have to find our unknowns. Our unknowns are the number of flyers that she hung on the west side of the building and the number of flyers she has left over. We can set up equations for these unknowns by letting represent the flyers she hung on the west side and represent the flyers that she has left.

because she hung half as many flyers on the west side as she hung on the east side. When we half something we always divide by .

To find the total number of flyers that she hung we add the amount of flyers on the east side and the amount on the west side.

To find how many flyers she has left, we subtract that total flyers that were hung from the flyers that she started with.

To solve this problem, we first have to find our unknowns. Our unknowns are the number of laps he swims on Wednesday and Thursday and the number of laps he swims on Friday. We can set up equations for these unknowns by letting represent the laps that he swims on Wednesday and Thursday and represent the number of laps he swims on Friday.

because when we triple something we multiply by .

because he is swimming less laps than he did on Monday, which means we subtract.

To find the total amount of laps that he swam, we need to add up the laps that he did each day.

To solve this problem, we first have to find our unknowns. Our unknowns are the number of miles he runs during the week and the total miles that he runs. We can set up equations for these unknowns by letting represent the miles that he runs during the weekdays and represent the total miles that he runs in week.

because he is running miles times.

because to find the total we need to add the miles he runs during the week and on the weekend.

To solve this problem, we first have to find our unknowns. Our unknowns are the number of miles he runs during the week and the total miles that he runs. We can set up equations for these unknowns by letting represent the miles that he runs during the weekdays and represent the total miles that he runs in week.

To solve this problem, we first have to find our unknowns. Our unknowns are the number strawberries and raspberries she puts in the fruit salad. We can set up equations for these unknowns by letting represent strawberries and represent raspberries.

because she has times as many strawberries than watermelon.

because when we half something we always divide by

Now we need to add the watermelon, strawberries, and raspberries together to find our total.

To solve this problem, we first have to find our unknowns. Our unknowns are the number strawberries and raspberries she puts in the fruit salad. We can set up equations for these unknowns by letting represent strawberries and represent raspberries.

because she has times as many strawberries than watermelon.

To solve this problem, we first have to find our unknowns. Our unknowns are how many meerkats there are total (T) and how many meerkats are left in the burrow (L).

because there are families of meerkats and each of them has members of the family. Each is a keyword for multiplication so that gives us a hint.

because there are meerkats total in the burrows and meerkats are subtracted because they left the burrow.

There are meerkats left in the burrows.

To solve this problem, we first have to find our unknowns. Our unknowns are how many baseball cards Patrick received in total (T) and how many cards each child will receive (C).

because he received cards from his friend and then another from his uncle. The cards would be added together to find the total.

÷ because there are cards total and they are being shared equally among Patrick AND his two brothers so there are children total. "Shared equally" is a keyword for division.

Each child will receive cards in total.

To solve this problem, we first have to find our unknowns. Our unknowns are how much did it snow during the weekdays (W) and how much did it snow on Saturday (S).

because we need to know how much it snowed during the weekdays in total. We must add together the amount of snow from Monday, Tuesday, Thursday, and Friday.

because it snowed times as much on Saturday as it did the rest of the week. The total snow from the weekdays will be multiplied by to find out how much it snowed on Saturday.

On Saturday it snowed a total of inches.
