Jorge has saved $15.50. Janet saved 1/5 of the amount that Jorge saved. Rob saved 12 times as much of Janet. What is the total s

KiRa [710]

Answer:

$55.80

Step-by-step explanation:

First, find how much Janet saved by finding 1/5 of 15.50:

15.50/5

= 3.1

Find how much Rob saved by multiplying 3.1 by 12:

3.1(12)

= 37.2

Then, find the total saved amount by adding them all together:

15.50 + 3.1 + 37.2

= 55.8

So, they saved $55.80 in total

Write an equation of the line passing through the points (4.15) and (-1. - 15).

jolli1 [7]

Answer:

y = 6x - 9

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Point (4, 15)

Point (-1, -15)

Step 2: Find slope m

Substitute: $m=\frac{-15-15}{-1-4}$
Subtract: $m=\frac{-30}{-5}$
Divide: $m=6$

Step 3: Find y-intercept b

Define: y = 6x + b
Substitute: -15 = 6(-1) + b
Multiply: -15 = -6 + b
Isolate b: -9 = b
Rewrite: b = -9

Step 4: Write linear equation

Substitute in all variables.

y = 6x - 9

And we have our answer!
