2x + (2)9 = 48
2x + 18 = 48
Get 2x by itself
2x = 30
x = 15
Answer:
1:3
Step-by-step explanation:
There are 60 marbles
15 are blue
60-15 = 45 are not blue
Ratio of blue : not blue
15:45
Divide by 15
15/15 : 45/15
1:3

Answer:
The solution is that there are 26 students in her class
Step-by-step explanation:
We know that 15 of her student are girls, and since there are more girls than boys in the class, there can at most be 15+14= 29 students in her class.
We need to find a number x between 16 (in the case where there is only one boy in the class) and 29, for which x/4 gives a remainder of 2, and x/5 gives a remainder of 1.
The numbers between 16 and 29, which when divided by 4 gives a remainder of 2 are:
18, 22, and 26
You can check yourself that these give a remainder of 2.
So it is one of these numbers. But the solution must also fulfill that the number divided by 5 gives a remainder of 1.
18/5 = 15 + remainder=3
22/5 = 4 + remainder=2
26/5 = 5 + remainder=1
Thus the only possible solution is 26.
