We are given the following numbers: 13, 14, 22, 52, 63, 74. calculate a by adding the numbers and then rounding the sum to the nearest ten. calculate b by first rounding each number to the nearest ten and then adding the rounded numbers. what is a-b?

a-b=10

Step-by-step explanation:

add all the numbers then round

13+ 14+ 22+ 52+ 63+ 77=241

Round to the nearest ten

a =240

first rounding each number to the nearest ten and then add

13+ 14+ 22+ 52+ 63+ 77

10+10+20+50+60+80 =230

b= 230

a-b = 240-230

      = 10

22

step-by-step explanation:

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
