Bill is in a class of 15 boys and 35 girls. 40% of the students in class take the bus to school. How many students did not take the bus to school ?

60% don’t take the bus

Step-by-step explanation:

We know the % = a number /100.

We know the % of students that take the bus is =40%

what we don’t know is (X) that represents the remaining percentage. so let set up the problem like this.

(X)+40=100

X=100-40

X=60

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
