Answer:
he needs 17/8 gallons of milk to make 30 milkshakes and this is proportional relationship
Step-by-step explanation:
3/4 divided by 12 = 1/16
gallon to make 1 milkshake and
1/16 x 30 = 17/8 gals. to make 30 milkshakes,
it's proportional because 3:4 > 15:8
Substitute 2x as y:
3x + y = 5
3x + 2x = 5
5x = 5
x = 1
Now, substitue 1 as x into one of the two equations:
y = 2x
y = 2(1)
y = 2
Hope this helps!
Step-by-step explanation:
umm I think it's my dude .4
So 3:4::198:?. 3 is to 198 as 4 is to ?. You're solving for ? so you want that on the top of the fraction. 4/3=?/198. Multiply both sides by 198. ?=(4/3)(198)=264 women. Then add the men. 264+198=462 workers.
Check your work. (462/7)*3=198 men.
