Rashida wrote these steps to find the estimated difference between 85 and 46.

step 1: 85 rounded to the nearest ten is 80.
step 2: 46 rounded to the nearest ten is 50.
step 3: the term difference means "to subtract.”
step 4: the estimated difference between 85 and 46 is
80 – 50 = 30.

in what step did her first error occur?

step 1
step 2
step 3
step 4

In Step 1 the first error occur.

Step-by-step explanation:

Given:

Step 1: 85 rounded to the nearest ten is 80.

Step 2: 46 rounded to the nearest ten is 50.

Step 3: The term difference means "to subtract.”

Step 4: The estimated difference between 85 and 46 is

80 – 50 = 30.

Now, we see in the step 1 it is that 85 rounded to the nearest ten is 80.

But the number 85 rounded to the nearest ten is 90.

As we round the number we check the last digit if it is 5 ,6,7,8 and 9 the number rounded up.

And if the last digit is 1,2,3 and 4 the number is rounded down.

Therefore, in Step 1 the first error occur.      

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

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
