Ax=15+bx
ax-bx=15
x(a-b)=15
x=15/(a-b)
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.
Answer: a
Step-by-step explanation:
44 times 3 =$132 for vases
x it is flowers, the price of one flower is $2
2x +132 must be less or equal 308
F(8) is basically saying that x=8, so the problem would be 8+11=19 im pretty sure :)
-3x+(-15)+8=2x+8-6
45x+8=2x+2
not equal
