Answer:

480 pounds.

Step-by-step explanation:

By proportion:

8/3 = x/180    where x is the weight on Jupiter.

A taxi charges $2.50 for the first mile and $0.40 for each mile after that. The expression below shows how to find the total cos
Svet_ta [14]

The expression which shows the total cost is 2.50+0.4x and the cost of riding 20 miles is $10.50.

Given a taxi charges $2.50 for the first mile and $0.40 for each mile

We are required to make an expression showing total cost and total cost of a 20 mile ride.

let the miles ride by tax be x.

Total cost of the product or service=Number of units*price of one units.

We have been given that $2.50 is fixed so we will not multiply our variable charge with $2.50 and multiply 0.40 with x.

So,the expression showing looks like 2.50+0.40x.

Now to find the cost when taxi travels 20 miles, we have to put x=20,

Cost=2.50+0.40*20

=2.50+(40*20)/100

=2.50+800/100

=2.50+8

=$10.50

Hence the expression which shows the total cost is 2.50+0.4x and the cost of riding 20 miles is $10.50.

Mr hopper did the rest need help

Let g = graph paper and r = ruler

1st equation: 5g + 30r = 40

2nd equation: 12g + 20r = 44

Multiply the 2nd equation by -1.5 to cancel out the r's

2nd equation: 12g + 20r = 44 x -1.5 = -18g - 30r = -66

Now add the 1st equation to that:

-18g + 5g = -13g

30r -30r = 0

40 -66 = -26

The new equation becomes -13g = -26

Divide both sides by -13

g = -26 / -13

g = 2

This means each pack of graph paper cost $2.

Now replace g with 2 in the first equation to solve for the cost of a rule:

5(2) + 30r = 40

Simplify:

10 + 30r = 40

Subtract 10 from each side:

30r = 30

Divide both sides by 30:

r = 30 / 30

r = 1

Each rule cost $1.
