Aclass used cars and vans to go on a field trip because of the buses were already in use the use 12 vehicles to go on the trip each car holds for students in each van holds 11 students if 83 students went on the trip and how many of each type of vehicle did the class use
answer

5 vans   7 cars

Step-by-step explanation:

c=cars         v=vans

c+v= 12

c =( 12-v)

11v + 4(12-v) = 83

11v + 48-4v = 83

7v = 35

v= 5

c = 12-5         c = 7

7 cars x 4 students = 28 students

5 vans x 11 students = 55 students

55+28 = 83 students

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
