Answer:
a = 6
Step-by-step explanation:
first try to divide all numbers by 3 and the add 4 to it until you get 6
Let wind speed = x mph
when she rode 2 miles against the wind we have:-
speed = distance / time so
20 - x = 2 / t -------(1) where t is the time she took.
when riding with the wind we have
20 + x = 3 / t--------(2) adding equations (1) and (2):-
40 = 2/t + 3/t
40 = 5/t
t = 5/40 = 1/8 hr
x = 20 - 2 / 1/8 = 20 - 16 = 4
Wind speed was 4 mph Answer
Answer:
The shoe is 0.25 or 1/4 meters long.
Step-by-step explanation:
Standard form;
(x - 2)² + (y - 6)² = 49
the center-radius form of the circle equation is in this format;
(x - h)² + (x - k)² = r²
so the center of the circle is; (2, 6)
so the radius of the circle is; 7
hope that helps, God bless!
