The ration is 4 cups water:1 cup vinegar so c cups water:12 cups vinegar 4 water/1 vinegar =c water/12 vinegar cross multiply so 12 times 1 and 4 times c so you get 12/4c divide both sides by 4 and you get 3 c=3
A - 8/10 = 4/5 B - 1/2 =/ 7/12 C- 3/4 =/ 8/12 D 2/3 = 4/6
Answer:
20 minutes on the stationary bike
10 minutes on the treadmill
Step-by-step explanation:
x = minutes on bike
y = minutes on treadmill
x + y = 30
12x + 15y = 390
x = 30-y
12(30-y) + 15y = 390
360 - 12y + 15y = 390
3y = 30
y = 10
x + 10 = 30
x = 20
