A truck can be rented from Company A for $80 a day plus $0.30 per mile. Company B charges $20 a day plus $0.50 per mile to r

mylen [45]

Write equations for both companies:

Company A = 80 + 0.30x

Company B = 20 + 0.50x

X = number of miles.

Set the equations to equal and solve for x:

80 + 0.30x = 20 + 0.50x

Subtract 0.30x from both sides:

80 = 20 + 0.20x

Subtract 20 from both sides:

60 = 0.20x

Divide both sides by 0.20:

x = 60 / 0.20

x = 300

The answer is 300 miles.

Find the x and y of x-3y=15 and -2x-4y=10

Minchanka [31]

Use elimination to create a one variable equation.

x-3y=15 -> 2x-6y=30

2x-6y=30

+(-2x-4y=10)

------------------

-10y=40

Then solve (for y in this case).

y=-4

Now we can use the value for y to solve for x.

x-3y=15 -> x-3(-4)=15 -> x=3

Monica built a porch that contained 2 different colors of bricks to create a pattern. She purchased the red bricks for $7 each a

ahrayia [7]

Equation #1: x+y=40

Equation #2: 7x+4y=193

Monica bought 11 red bricks.

Step-by-step explanation:

Given,

Cost of one red brick = $7

Cost of one gray brick = $4

Total spent on bricks = $193

Total bricks bought = 40

Let,

x represents the number of red bricks bought.

y represents the number of gray bricks bought.

What is the system that models this situation?

Equation #1: x+y=40

Equation #2: 7x+4y=193

How many red bricks did Monica purchase?

Multiplying Eqn 1 by 4

$4(x+y=40)\\4x+4y=160\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(7x+4y)-(4x+4y)=193-160\\7x+4y-4x-4y=33\\3x=33$

Dividing both sides by 3

$\frac{3x}{3}=\frac{33}{3}\\x=11$

Monica bought 11 red bricks.
