Alright, so 9^(-1/2) would mean that we have 1/(9^(1/2)). Since 9^(1/2) is the square root of 9 (1/3 would be the cube root, etc.), we have 1/sqrt(9)=1/3. For 3/(1/3), we have (3/1)/(1/3), which is (3/1)*(3/1)=9. Squaring 9, we get the cube root of 81 which is around 4.3
Answer:
15. 1/3 (33%)
16. 1/6 (16.66%)
17. 1/2 (50%)
18. 1/2 (50%)
19. 1/1 (100%)
20. 0/1 (0%)
Step-by-step explanation:
Answer:
a) t=5
5+5+5=15
b) x=11
11-8=3
or you can add 3 to both sides and x=11
c) w=3
7(3) = 21
21+3=24
or subtract 3 from both sides to get 7w=21
then divide by 7 on both sides to get w=3
