Number 1 is 1. Because it's a number pattern 10-3=7.Then 7-3=4.Finally 4-3=1.
Answer:
k = -1
Step-by-step explanation:
6(5k-8)-20= 11(2k-3)+3k | Given
30k - 48 - 20 = 22k - 33 + 3k | Distribute
30k - 28 = 25k - 33 | Add numbers & combine like-terms
30k = 25k - 5 | Add 28 to both sides
5k = -5 | Subtract 25k from both sides
k = -1 | Divide -5 by 5
If you add them all together, you'd get 157. Then you divide by 7 and you'd get 31.4
