Step-by-step explanation:
If there are 40 kids and 22 of them play soccer that leaves you to subtract 22 from 40 which gives you 18. After that, you put the rest of the 18 students over a total of 40 and divide to get the decimal .45 and if you convert that into a percent you are left with 45%.
1. 40-22=18
2.18/40=.45
3.45=45%
Answer:
25404192 mi is the correct answer
X should be around 1.5625, assuming that -4 is squared is not in a parenthesis. So, the problem should be -20=-4^2(sqrtx). Divide -20 by -16 to get 1.25. Then square 1.25 and sqrt x to get 1.5625.
