Explain how you would round the number 33 and 89 to estimate their sum

You can round numbers based on what number they are closer to.

In example, for the number 33, you would be either rounding to 30 or 40. Since 33 is closer to 30, you would round that to 30.

Between 80 and 90, 89 is closer to 90.

You could then add 90 and 30 to get 120, and then estimate that 33+89 is also around 120.

Hope this helps! :)

When rounding:

- If the following number is less than 5, the previous number remains the same.

- If the following number is 5 or greater, the previous number increases by 1.

Therefore, you would round 33 to 30 since the following number after 3 is 0. 89 would round to 90 since the number following 8 is greater than 5.

30+90=120

The estimated sum would come out to 120.

d is correct

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
