Answer #1- 8 mins
Answer #2-$0.571
Explanation for #1:
For this first equation you need to find 1 mike per ___ minutes. To get from 10 to 1, you need to divide by 10. This can also be put into this equation—
10x=80
So, to find how many minutes for each mile, divide 80 by 10. This will result in 8. This means that Dan ran 1 mile in 8 minutes.
Explanation for #2:
For this next one we see that we need to find how much Yoko spent on each pound of rice.
Since we are trying to find 1 pound of rice per ___ dollars, we need to divide both 14 and 8 by 14. This can also be put into this equation—
14x=8
Once this is done we know that 1 pound of rice is equal to 0.571428571428571 cents. But, since you are required to round to the nearest hundredth, the answer will only be $0.571.

Answer:hey must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.
Step-by-step explanation:
For this i will not give the answer but i will guide you one how to do it
first of all if the line is perependicular to -1/5x-1/8 that mean its the opposite and swicht signs. so since jt only effects the slope the slpoe for the other equation will be from -1/5 to 5 since we flipped the fraction and flipped the sign. next it also says that the new line k has to pass through (0,0) that would mean since (x,y) equals (0,0) we would have to plug the x and y which is the two zeros giving us and equation like this
0=5(0)+b
if we make in it slope intercept form it would have to be y=mx+b
then if you slove for b you will put it into the equation
y=5x+b
