Alright, lets get started.
Suppose total number of dancers in school = x
We have given in question, 42 % of total dancers are ballet dancers.
So, we could find number of ballet dancers by finding 42 % of total dancers.
Number of ballet dancers = x * 42 %
Number of ballet dancers = x * 42/100 = 0.42 x
As per given in question, there are 63 ballet dancers in school.
Which means 0.42 x = 63
Dividing 0.42 from both sides
0.42 x / 0.42 = 63 / 0.42
x = 150
Hence number of total dancers in school = 150 : Answer

Answer:
4.8 feet
Step-by-step explanation:
Combine like terms.
Since 7x and 6x both have a variable of x, you can combine them.

After that, you are left with:

You also have two numbers without variables; 11 and 3. You can also combine those.

So, your final answer would be:

Answer:
m=47
Step-by-step explanation:
I am better at substitution, but you want to get the equations as similar as possible, but are the opposite, so you can cancel it out.
