726 x 5 estimate then find the product

3500.

Step-by-step explanation:

We have been given a product of two numbers . We are asked to estimate our given number and then find the product.

Since the tens place in 726 is less than 5, therefore, we will round down 726 to nearest hundred that is 700.

The estimated product of our given numbers would be:

Therefore, our estimated product would be 3500.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
