Question

Explain how to got the answers

Answer 1

7 question a.)= $5.82

7 question b.)= 0.65 + 0.65 + 0.65 + 1.29 + 1.29 + 1.29 and the second way is

3. 87 + 1.95 = $5.82

8 question Answers are = A.) and C.)

A.) because addition doesn't matter when you switch because either way, your still combining to get your answer. for example 5+3=8  3+5=8

B.) multiplication is the same with addition for example 7 x 6=42 6 x 7=42

for question 9 you should plot a dot a number 3

for 10 you should plot a dot at 2, 3, 4 and 5 because x>1 means every number higher than 1

11 question  table: -2, +4, +7, -4, +5

12+4= 2+7=9-4=5+5=10

10 divided by 5 = 2 your answer is 2

this is the answer because mean is to add up all the number and divide by the number of numbers. in this case, when i added them all up i got 10. and there were 5 number so i divide that by 5 and 10 divided by 5 is 2.

i couldn't really see the 11 question part B.) too well, but i answered everything else. i hope this helps!
