let the number of visits be x

and the total cost be y

the total cost for the situation is modeled as

y=mx+c-----equation of a line

Step two:

given that x=23, we can solve for the totals cost as

Each grade level at Hooperville Schools has 298 students.

madreJ [45]

Answer:

(a) 3,874 students.

(b) 46,488 students.

Step-by-step explanation:

We have been given the each grade level at Hooperville Schools has 298 students.

(a) To find the number of students that attend Hooperville Schools, we will multiply the number of grades by 298.

$\text{Students that attend Hooperville Schools}=13\times 298$

$\text{Students that attend Hooperville Schools}=3,874$

Therefore, 3,874 students attend Hooperville Schools.

(b) We have been given that nearby district, Willington, is much larger. They have 12 times as many students.

To find the number of students that attend schools in Willington, we will multiply number of students at Hooperville schools by 12.

$\text{Students that attend Willington Schools}=12\times 3,874$

$\text{Students that attend Willington Schools}=46,488$

Therefore, 46,488 students attend schools in Willington.

If 3x x 10=22, what is the value of 5x +8?

scZoUnD [109]

Step-by-step explanation:

3x x 10 = 22

3x x 10 - 10 = 22 - 10

3x = 12

3x ÷ 3 = 12 ÷ 3

x = 4

5x + 8

5(4) + 8
