Question

A truck is rented at $40 per day plus a charge per mile of use. The truck traveled 15 miles in one day and the total charge was $115. Which equation can be used to find the charge x, in dollars, per mile traveled?

Answer 1

Okay! So the total was $115. We know that $40 of it was the day charge and x is the charge for the amount traveled.

Answer 2

So, equations have to have an equal sign. In this case, all the costs equal the total, $115.

Answer 3

i think its 40 + 15x = 115

Answer 4

Yup, you're correct

Answer 5

subtract 40 on both sides right?

Answer 6

can yall help me with another question ?

Answer 7

subtract 40 on both sides then divide 15 on both sides so it would be x=5 right?

Answer 8

Sure

Jacob wants to make a graph to show the relationship between temperatures in Fahrenheit and degrees Celsius. He plots the following points:

(11, -11.7), (15, -9.4), (25, -3.9), (35, 1.7), (45, 7.2)

He uses the following steps to plot the graph:


Label origin as (0, 0)
On x-axis label Temperature in Fahrenheit.
On y-axis label Temperature in degrees Celsius.
The scale on x-axis starts from 0 and goes up to 700 at intervals of 20.
The scale on the y-axis starts from -12 and goes up to 12 at intervals of 2.

Which of the following best describes the graph?
A) It will not be spread out horizontally across the entire coordinate plane because in Step 4 Jacob selected an incorrect scale on the x-axis.

B) It will not be spread out vertically across the entire coordinate plane because in Step 5 Jacob selected an incorrect scale on the y-axis.

C) It will not be spread out horizontally across the entire coordinate plane because in Step 2 Jacob plotted Fahrenheit instead of Celsius on the axis.

D) It will not be spread out vertically across the entire coordinate plane because in Step 3 Jacob plotted Celsius instead of Fahrenheit on the y-axis.

Answer 16

@rina1234, have you constructed the xy plot yet?

Answer 17

idk how to do it :(

Answer 18

I usually use graph paper to do it. There are youtube videos that can show you how.

Answer 19

But, just to give you an idea, it will look something like this:
