Sarah has three more than four times the money that Jessica has. Together they have $72. How much does each person have?

Jessica has $13,80 and Sarah has $58.20.

Step-by-step explanation:

Let j be the amount of money that Jessica has.

Let s be the amount of money that Sarah has.

s + j = 72

Since Sarah has 3 more than 4 times what Jessica has...

s = 4j + 3

So 4j + 3 + j = 72

5j = 69

j = 13.8

So Jessica has $13,80.

Therefore Sarah has $58.20.

which expression represents the approximate length of bc?

step-by-step explanation:

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
