Answer:
Solution given:
ratio of boys to the girls=5:3
let ratio be 5x and 3x
we have
5x+3x=40
8x=40
x=40/8
x=5
5x=5*5=25
3x=3*5=15

No of boys=25
No of girls=15
Answer:
The answer is the last option.
Step-by-step explanation:
Im positive its false because they dont add up
Neither because neither the cube root or square root of 240 is just one number
-3(x+3)= -3(x+1)-5
-3x+9=-3x+3-5
so you would have just distributed then you combine like terms and get
-3x+9=-3x-2
then add two to both sides and get
-3x+9=-3x-2
-3x+2=-3x+2
-3x+11=-3x
+3x+11=+3x
0x+11=0x
so 11+0x
divide both by zero and you get x+0
