Timothy bought 4 packages of cat food and 3 packages of dog food. Each package of cat food contained 7 cans, and each package of dog food contained 3 cans. How many more cans of cat food than dog food did Timothy buy?

Answers

Answer:

Step-by-step explanation:

4 times 7 is 28

3 times 3 is 9

Dog food = 3 x 3 = 9

28-9= 19

Brady recorded the number and color of cars in the parking lot. 45% of the cars in the parking lot were white. If Brady counted a total of 81 white cars, how many cars did he count in the parking lot?

Answers

Answer:

180 cars

Step-by-step explanation:

Like you can see in the picture, I like to set up a proportion, so 81 over X and 45 over 100. Then, you can cross multiply, so 81 x 100 = 8100 and then divide, 8100 ÷ 45 = 180, your answer!

180 is the answer sorry if I’m late to answer

Im so glad I could help! I hope you pick my answer as the Brainliest!

Answer:

Step-by-step explanation:

Since this is a test, I'll give a hint.

This problem can be a little confusing, but thats ok! The problem is trying to make two models, (each model is a number) and asking you to find what the addition sentence is.

If that makes you confused, then that's probably the right response! The first thing you would need to know is what are they dividing the whole circles of? Thirds? Seconds? Sixths?

You would then need to know how many whole numbers are there. "Whole numbers" are basscially fully shaded circles.
