Answer:
Hey there! ok , so your equation would be 28 / 3
Step-by-step explanation:
The equation would be 28/3 because there are 28 students in the class and the ratio of boys to girls is 3-9 meaning that it is 1/3, which is the same as dividing by 3, so the equation would be 28/3

Answer:
n = (7/3)t
Step-by-step explanation:
Represente the unknown number by n. Then write the statement symbolically, as:
(3/7)n = t
and then solve the above equation for n by multiplying both sides by (7/3):
n = (7/3)t
Three more than twice the number is 25
The number you're looking for is 25. Simply work backwards.
25 - 3 (three more...) = 22
22 ÷ 2 (twice the number) = 11
