ok well you would set up an equation 7miles/50 mins=xmiles/75mins then you would cross multiply 7*75=50x
then you simplify 525=50x
then divide both sides by 50 and you end up with 10.5
so she would run 10.5 miles in 75 minutes
Answer:
D - (D/5)
Step-by-step explanation:
Let's imagine that D equals 100 dollars -
Well, we know that to get 20% of an amount, we need to divide the amount by five. So let's do that -
100 / 5 = 20
We now know that 20% of 100 dollars is equal to 20 dollars. We have now finished the first part. On to the second part.
We now need to take away 20% of 100 dollars off of 100 dollars - this is the price of the item after the discount.
100 - 20 = 80 dollars.
We now fit in D instead of 100 dollars -
D - (D/5)
Step-by-step explanation:
4/5 divide
0.8 is the ans
Umm do have any pictures to help me answer it or anything?
Answer:
y=2x-2
Step-by-step explanation:
y=mx+b is point slope form.
let m= the slope
b=y intercept
the y intercept is -2
y=mx-2
then after finding the slope (2) put that in
y=2x-2
