This question isn't phrased correctly, but I will assume it's asking about common denominators with fractions.
9/11 1/22
18/22 1/22
18 school days.
x*-8 would be -8x
then you would divide -8 by both sides
should get a decimal as your answer I believe
3 quarters and a dime a nickel and 4 pennies
1.) 16/100 and 0.16
2.) 7/10 and 0.7
3.) 6/10
4.) 73/100
5.) 6 9/10
6.)8 57/100
7.)0.70
8.)0.33
9.)7.20
10.)3.09
11.) 0.80
12.)0.48
13.)0.02
14.)0.55
15.)D
I hope all of these are correct and help
U use y=mx+b to find the slope, and the answer would be m=-3
