Answer:
8
Step-by-step explanation:
c^2 is 9, 2d is 4
9-4+3=8
To solve this, you need to isolate/get the variable "n" by itself in the equation:
Multiply 21 on both sides to get "n" by itself
Simplify the fraction
-18 = n
Answer:
M/6 = G/5
Step-by-step explanation:
We are given a relation between the numbers of students in two different groups. That relation can be used to write an equation.
<h3>Groups who bought M&Ms</h3>
If we consider M&M buyers to be 6 in a group, then the number of those groups is ...
M/6
<h3>Groups who bought gum</h3>
Similarly, the number of groups who bought gum will be ...
G/5
where there are 5 gum-buyers in each group.
<h3>Equation</h3>
The problem statement tells us that for each group of one kind, there is a matching group of the other kind. That is, the numbers of groups are equal:
M/6 = G/5
