Step-by-step explanation:
14. e= -25
16. y=7
18. -k=500
20. w= -20
22. x=21
24. y=0
hope it helps.
The answer to the top one is 243.
For 13. the answer is w = -1.
Here are the steps
1. subtract 5 from both sides ( 3w = 2 - 5)
2. simplify 2 - 5 to -3 (3w = -3)
3. divide both sides by 3 ( finally the answer is w = -1.
)
First you substitute the varibles with the correct number which would be 5=2(2)-3
Then you solve for it and your answer should be A. but I'm not a 100% sure because the sides do not equal
9 3/10, 3 8/10, 2 9/10
8/10 + 9/10 = 1 7/10
3+2+1 7/10 = 6 7/10
9 3/10 - 6 7/10 = 2 6/10
