9+ 8 =
2x 17
29 + 33 =
9 x 8 = 72
164 ÷ 2 =
half of 20 =
6 x 3 =
39 - 20 =
54 + 37 =

9+8=17 | 2×17=34 | 29+33=62 | 164÷2=82| 20÷2=10 | 6×3=18 | 39-20=19 | 54+37= 91|

Step-by-step explanation:

9+8 is 17 since 9+9 is 18 so you just remove a number to make it 17 which is the same thing that happened to the nine that turned into an 8.

17×2 is 34 b/c 17+17 is 34. details to follow.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
