(1 2/3) / 50 = x/60
cross multiply
50x = 60 * 5/3
50x = 100
x = 100/50
x =her walking pace is 2 miles per hr
Answer:
5x - 2y = - 2
Step-by-step explanation:
Given the 2 equations
- 2x + y = 0 → (1)
- 7x + 3y = 2 → (2)
Subtracting (2) from (1) term by term
- 2x - (- 7x) + y - 3y = 0 - 2, that is
- 2x + 7x - 2y = - 2
5x - 2y = - 2
$70 into 1:2:4
1+2+4 = 7
7 parts= $70
1 part = $70/7 ($70 divided by 7)
1:2:4 = $10:$20:$40
answer= $10:$20:$40
Hope this helps!! :)
