Answer:63%
Step-by-step explanation:
if 2years=25%loss
Then 5years=5/2×25%
=62.5%~63%
Answer:
%80
Step-by-step explanation:
Roberto overtakes Juanita at the rate of (7.7 mi)/(11 h) = 0.7 mi/h. This is the difference in their speeds. The sum of their speeds is (7.7 mi)/1 h) = 7.7 mi/h.
Roberto walks at the rate (7.7 + 0.7)/2 = 4.2 mi/h.
Juanita walks at the rate 4.2 - 0.7 = 3.5 mi/h.
_____
In a "sum and diference" problem, one solution is half the total of the sum and difference. If we let R and J be the respective speeds of Roberto and Juanita, we have
R + J = total speed
R - J = difference speed
Adding these two equations, we have
2R = (total speed + difference speed)
R = (total speed + difference speed)2 . . . . . as computed above
Answer:
36=x^2+5x
x^2+5x-36=0
(x+9)(x-4)
x= 4
x= -9
The Answer can be 4 or -9, see which option you have.
Step-by-step explanation:
Assuming that the order is
ok so
distance from greenvile to parker=29
distance from greenvile to hadley=?
distance from hadley to greenvile is 12 and 1/2 less than distance between parker and greenvile means
?=-12 and 1/2+29
add
-12 and 1/2+29=6 and 1/2
?=6 and 1/2 miles
