15 5/24 is the answer 3x5=15 3x8=24
Answer: There are 25 students in the class.
Step-by-step explanation:
Let there are total x students in the class,
Since, 20% of the total students want ice cream party,
⇒ The number of students who want ice cream party = 20 % of x
= 0.2 of x
= 0.2 x
According to the question,
5 students, out of total students, want ice cream party
⇒ 0.2 x = 5
⇒ x = 25
Hence, there are 25 students in the class.
P(1, 2), Q(3, 4)
we find the slope dividing the y over the x, that is:
m = (4 - 2)/(3 - 1) = 2/2
m = 1
and then use the line equation for a point and slope:
y - y1 = m(x - x1)
where (x1, y1) is a point through which the line passes, we use P(1,2):
y - 2 = 2(x - 1)
y - 2 = 2x - 2
y = 2x
therefore the slope is 2 and the y-axis intercept is 0

The answer is G. Think of the variable y as each additional copy. 12 times (y- # of additional copies). 15 is the starting pay of the first copy so you only need to pay 15 once. However, 12 depends on how many additional copies you have which is our missing number y
