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!
