Answer:
100
Step-by-step explanation:
Ratio is a fraction, so ratio of boys to girls would be written as [let boys be "b" and girls be "g"]:

Also, there are 250 more girls than boys, so we can write:
g = 250 + b
Lets substitute this into "g" of the ratio we wrote and cross mulitply and solve for b:

The number of boys = 100
$11.25 because 10 times 1.125 is equal to 11.25
Answer:
There are no like terms.
Step-by-step explanation:
basically that is your answer you can not solve so it will be 3ax – 3ay – 2bx + 2by
C. since you are constantly dividing by 5
100 ÷ 5 = 20
20 ÷ 5 = 4
4 ÷ 5 = 0.8
And so on...
