Answer:
Step-by-step explanation:
Assuming you are asking for
85,000,000 + 2.9 x 10^5 =
8.5 x 10^7 + 2.9 x 10^5 =
10^5 ( 8.5 x10^2 + 2.9) =
10^5 ( 850+2.9) =
10^5 ( 852.9) =
10^5 x 8.529 x 10 ^2=
8.529 x 10^7
or
85,000,000 + 2.9 x 10^5 =
85,000,000 + 290,000 =
85290000 =
8.529 x 10 ^7 (because we moved 7 spots to the left)
B) y=x-4 not sure how to explain it, but because the y intercept is -4, it is almost certain that the last number will ne -4 and since x is equal to 4 y must equal x-4. Might be wrong though ('o')
Answer:
Supplementary
Step-by-step explanation:
∠ADW = 60 +90 = 150°
∠ADW + ∠YDW = 150 + 30 = 180°
If sum of two angles is 180, then they are supplementary
