Answer:
p = q/5 - 9r/5
Step-by-step explanation:
Step 1: Write equation
5p + 9r = q
Step 2: Solve for <em>p</em>
<u>Subtract 9r on both sides:</u> 5p = q - 9r
<u>Divide both sides by 5:</u> p = q/5 - 9r/5

Answer: $112, 16 trips
Step-by-step explanation:
You would plug 9 into the equation for t. Then for the total amount until she was out of money you would divide 256 (her total amount of money) by 16 (the toll cost per trip)
Answer:
y=7x+3
Step-by-step explanation:
Hi there!
We are given the equation y=7x-5 and we want to find the equation of the line that is parallel to it, and contains the point (4,31)
First, let's find the slope of y=7x-5, since parallel lines have the same slopes
The line y=7x-5 is written slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
Since 7 is in the place of where m is, the slope of the line is 7
It's also the slope of the line parallel to it.
We can substitute 7 as m into the formula y=mx+b for our new line:
y=7x+b
Now we need to find b
Since the equation will pass through the point (4, 31), we can use it to solve for b; substitute 31 as y and 4 as x
31=7(4)+b
Multiply
31=28+b
Subtract 28 from both sides
3=b
Substitute 3 as b
y=7x+3
Hope this helps!
