I think this might be the answer you're looking for m^3n/p^2
Answer:
-40
Step-by-step explanation:
(5x-13)=-8x then- 8x×5 =-40
Ax+By=C , where A=0, B is positive , and C is negative
so y = - C/B (less than 0)
So answer is the last one. (y = -3)
Boys : Girls = 2:7
let the no. of boys be x
so no of girls = 250+x
so, x:(250+x) = 2:7
x/(250+x) = 2/7
7x = 500+2x
7x-2x = 500
x = 500/5 =100
.00003 times 100000 is 3. Then you divide 3 by 2 which is 1.5
