It's C) -3/4If you need the steps let me know. (:
Both missing angles are 45°
Yes
Example: some multiples of 8 are 8,16,24,32,40 and these are multiples of 2
Answer:
k = 4
Step-by-step explanation:
-9 +8k = 7+4k
Subtract 4k from each side
-9 + 4k = 7
Add 9 to each side
4k = 16
Divide by 4
k = 4
Plug in the value you got for k:
-9 + 8(4) ? 7 + 4(4)
-9 + 32 ? 7 + 16
23 ? 23
23 = 23
