Answer:
Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.
Step-by-step explanation:
Given:
Number of boys = 72
number of girls = 90
We need to arrange students in rows with equal number of only boys and only girls.
To find the maximum number (x) of boys or girls in each row, we will find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that 'x' divides both numbers evenly without a remainder.
Now to find GCF we will factorize both numbers.
from above we can say that;
GCF = 
Hence Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.
A.) Simplifying the equation would lead you to 15x^2-3x+9
b.) You know your answer is correct because you're adding the two polynomials together. 9x^2+6x^2 is 1tx^2. Now you have 2x-5x and since the negative is bigger, you get -3x. Then 5+4 is 9. You have no like terms therefore your answer is 15x^2-3x+9
There are 5 quarters and 3 dimes.
Let's illustrate it as 
Now adding 5 quarters and 5 dimes, we get 
.
5/3 is not equal to 10/8 hence it no longers has the ratio of 5:3 but now has the ratio of 5:4
Answer:
b). (0, 4)
