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
3/4 x 21
=
3/4 x 21/1
=
63/4
Answer:
L= 40
Step-by-step explanation:
replace the variables for R and D with the given.
100- 1.5(40)
100- 60
L=40
Answer:
Base of figure A = 12 units
Step-by-step explanation:
Given:
Base of figure B = 15 units
Ratio of figure A to figure B = 4:5
Find:
Value of X
Computation:
X / 15 = 4 / 5
x = 4(15) / 5
x = 12
Base of figure A = 12 units
as you should know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".
