Hey there! I’m happy to help!
Let’s use the variable g to represent the girls. This ratio shows that there are twice as many boys as girls (boys=2g)We also see that there are 18 more boys that girls. Let’s set up an equation
g+18=2g
We subtract 18 from both sides
g=2g-18
We subtract 2g from both sides.
-g=-18
We divide both sides by -1
g=18
Therefore, there are eighteen girls.
I hope that this helps! Have a wonderful day!

Answer:
Step-by-step explanation:
Apply distributive property
20-30(4z+4*1-6(z-2)
multiply 4 by 1
20-30(4z+4-6(z-2))
apply distributive property
20-30(4z+4-6z+12)
multiply -6 by -2
20-30(4z+4-6z+12)
subtract 6z from 4z
20-30(-2z+4+12)
add 4 and 12
20-30(-2z+16)
apply distributive property
20-30(-2z)-30*16
multiply -2 by -30
20+60z-30*16
myltiply 30 by 16
20+60z-480
subtract 480 from 20
60z-460
