A. T= d/r
A good way to remember this is by making a pyramid with 3 parts and putting distance at the top and rate and time in the other two parts. This way you can visibly see the equation and use it if you need to find one for rate.
B. It's reasonable to write distance as a positive number because distance is always positive. You are not able to have a negative distance. Imagine someone standing on a side walk. Even if they are not moving, their distance is 0 which is positive. If they move backwards or forwards, their distance is still positive because it is more than that 0 and they are gaining something.
C. Just plug in the numbers into the formula.
T= d/r
T= 32.12 m /<span>8.8 m/min
T= 3.65 min

Answer:
6+5x
Step-by-step explanation:
You cannot combine a given with a variable as such 6 + 5x is not combinable and will be left as such. Therefore the second one.
6 added to = 6+ (five times a number) = 6+(5x) = 6+5x

Answer:
it would take 20 months and it would cost $6450
Step-by-step explanation:
in order to solve this question we need to equate the amount at each dealer against one another
<h2><u>Find the number of months</u></h2>
make the months as an unknown variable (x)
2450 + 200x = 2950 + 175x
now make x the subject of formula
200x - 175x = 2950 - 2450
25x = 500
x = 500/25
x = 20
the amount would be the same in <u>20 months </u>
<h2><u /></h2><h2><u>to find the amount it would be after those months</u></h2>
replace x with 20
2450 + 200 (20) = 6450
<u>$6450 </u>
Answer:
See below.
Step-by-step explanation:
The first 4 means 4 * hundred thousand
The second 4 means 4 * ten thousand.
So the first 4 is ten times the value of the second.
