2a(2+b) and 4ab. Not equivalent
Step-by-step explanation:
hope this helps:)
Net income is all cost factors put together, so total income minus total expenses.
15000 + 258 + 2562 = 17820
1346 + 1598 + 48 = 2992
17820 - 2992 = $14828
Answer:
r = 6 mph and f = 11 mph
Step-by-step explanation:
Representations:
1) speed of faster cyclist: f = r + 5
2) speed of slower cyclist: r
Distances covered:
(r + 5)(5 hr) + r(5) = 55 mi (total distance covered)
Then 5r + 25 + 5r = 55, or, after reducing this equation:
r + 5 + r = 11, or
2r = 6
Then r = 6 mph and f = 11 mph
<span>So, (72)(3/8) = 27, and 72-27 = 45 must go in the second group.</span>
