<h2>(x, y) = (21/13 , 84/13)</h2>
Step-by-step explanation:
x + 3y = 21
- 4x + y = 0
y = 4x
<h2>_____________</h2>
x + 3y = 21
x + 3(4x) = 21
x + 12x = 21
13x = 21
x = 21/13
y = 4x
y = 4 (21/13)
y = 84/13
(x, y) = (21/13 , 84/13)
10/3mi/1hr
10/3mi/1hr*21/8hrs=10*21/24=10*7/8=70/8miles
=35/4miles=8 3/4 miles
61 because you always multiply first 60 x 0= 0 so now we have 60+1 which is 61
