In math and and other types of school stuff :) if that's what your asked
Answer:
18/5 miles
Step-by-step explanation:
let d be the mountain dist path
upward biking
x miles - 1 hr
d 45 mins
3x/4 = d
riding down
x+3 - 60 min
d. - 20
(1/3)(x+3) = d
(x+3)/3 = 3x/4
4x+12 = 9x
x = 12/5
d =( 12*3)/(4*5)= 9/5
upward+downward = 2*(9/5) = 18/5
The temperature would be -7 degrees
<span>y = -3x + 4
x + 1/3y = 4/3
Substitute the first expression into the second equation for y:
</span>x + 1/3(-3x + 4) = 4/3
x - x + 4/3 = 4/3
4/3 = 4/3
Answer;
All real numbers are solutions.
Hope this helps.
