Answer:
36 oz.
Step-by-step explanation:
If a 12 Oz soft drink is 80 cents, and we need to find out much many oz in in 2.40, we need to multiply 12 by 3.
because: 2.40=.80×3
so: 12×3= 36
Adult tickets + kids tickets = 120$
Y represents kids tickets
Z represents adult tickets
Z = twice kids tickets = 2Y
In ecuation:
Z + Y = 120$
Replace Z with 2Y
2Y + Y = 120 $
3Y= 120 / divided by 3
Y = 40$
You know the cost for 1 kid ticket
40 : 4 = 10 kids tickets sold
Z = 2x 40= 80$ for adult tickets
80:8 = 10 adult tickets sold
Answer:
The value of x in the equation 2x + 3y =36, when y = 6 is 9
Step-by-step explanation:
Solution:
we get 2x + 3(6)= 36
2x + 18 = 36
2x = 36-18
2x = 18
x =9
