Answer:
25
Step-by-step explanation:
If 5/8 are boys then
1 - 5/8 = girls
3/8 = girls
3/8 of the total are girls
Let x = total
3/8 ( x) = 15
8/3 * 3/8 * x = 15 * 8/3
x = 40
There are 40 total students
5/8 are boys
5/8 * 40
25 are boys
Answer:
12x+4x-7y+45b+78a-44b+1a+1z+0d+1.1a+1.1a+2+2+2
The coefficient would be 1
before every variable, there is a one
So, x is equal to 1x
x+x is 2x
hope this helps:)
