You would do 29.85 ÷ 3 which equals 9.95. You would do the in verse operation. Hope I helped you.
Subtract the second equation from the first equation.
x = -1
Plug -1 back in to either equation and solve for y.
3(-1) + y =-10
-3 + y = -10
Add 3 to both sides
y = -7
CHECK
3(-1) -7 = -10
2(-1) -7 = -9
(-1, -7)
1.1=1
2.2=4
3.3=9
4.4=16
5.5=25
6.6=36
7.7=49
8.8=64
9.9=81
10.10=100
11.11=121
12.12=144
13.13=169
I'm pretty sure this is right because there is 1.5 per one Wich is also written as a fraction
I believe the answer is C. It is the only one that makes sense
