Hey there! I'm happy to help!

We want to isolate y on one side of the equation to see what it equals. To do this, we use inverse operations to cancel out numbers on the y side and find the correct value.

1/3y+4=16

We subtract 4 from both sides, canceling out the +4 on the right but keeping the same y-value by doing the same to the other side.

1/3y=12

We divide both sides by 1/3 (which is multiplying both sides by 3) which will cancel out the 1/3 and tell us what y is equal to.

y=36

Now you know how to solve basic equations! Have a wonderful day! :D

The number of girls in the Middle School Cyber Club was 6 more than double the number of boys, and in total there were 48 middle
Wittaler [7]

Answer:

g = number of girls;

b= number of boys

we know that: g= 6+2b

     and that: g+b= 156 kids in total

so we may write  g+b=(6+2b)+b=6+3b

                 but g+b= 156

so 6+3b = 156 => 3b= 156-6=150 =>   b=150/3=50 => b = 50 (number of boys)

g= 6+2b= 6+2 x 50= 106 => g =106 (number of girls)

Please help me question is in the picture
tekilochka [14]

Answer:

172.70 sq. ft.

Step-by-step explanation:

The surface area of a circular cone is

SA = \pi r^{2} + \pi rl       r = radius of base         l = slant height

r = 4.4    and     l = 8.1

SA = 3.14 (4.4^{2}) + 3.14(4.4)(8.1)\\

SA = 3.14(19.36) + 111.9096

     = 60.7904 + 111.9096

     = 172.70 sq. ft.
