QUESTION-
what is three eighths + 9x negative one half
ANSWER-
3/8 + 9x (- 1/2)
To get this I multiplied 4*9.30to get 37.20. you can do the rest.
I got...
2a(to the fourth power) plus 12a(to the second)b(to the second). I also checked this online.
It’s c cuz I took the test AND ITS SOOO EASY
There will be 18 girls in a group of 16 boys.
you divide 72 by 16 and get 4.5.
then you divide 81 by 4.5 and get 18.
That is how you get 18 girls in a group of 16 boys.
Hope that helped.
