Answer:
The total amount of students in the class would be 30. The total amount of girls would be 12.
Step-by-step explanation:
60% * x = 18
(60/100) * x = 18
6x/10 = 186x = 18 * 10
6x = 180x = 180/6 = 30
The total number of students in the class is 30.
Number of girls in the class = 30 - 18 = 12
So there are 12 girls in the class.

Answer:
binomial
Step-by-step explanation:
bcoz highest power(degree) is 2
Set this up as follows...
12x - 10 = 7x + 20
solve for x
X is 6
sub VW=7X with 7•6
VW=42
check by subbing also for UW
72 - 10 is 62
uV plus VW equals 62. it checks out.
The Value Of X To The Nearest Tenth Is 2.5
