Using Long Division, pic below
Your remainder is -61
Answer:
60 mph
Step-by-step explanation:
We don't know how far Jimmy drives in each direction. Let this distance be d. Then, d = rate * time, and d = r(2 hours) (where r represents his speed while driving to the ferry).
But it's also true that d = (r - 20 mph)(3 hours).
Equating d = r(2 hours) and d = (r - 20 mph)(3 hours), we get:
r(2) = (r - 20)(3), or 2r = 3r - 60.
Subtracting 2r from both sides yields 0 = r - 60, so that r = 60 mph.
Jimmy averaged 60 mph on the outbound trip.
Answer:
There are mathematics you could purchase that has answer sheets, what grade you in?
That picture doesn’t show that they are supplementary angles it’s shows that they are complementary angles.
First we need to convert the mixed umber to an improper fraction...
3 2/9
Multiply the denominator by the whole number the. add the numerator the. put that over the original denominator.
9×3 = 27 + 2 = 29/9
now we can multiply the two fractions... numerator × numerator and denominator × denominator.
29/9 × 7/3 = 203/27
reduce the fraction to 7 14/27
