Answer:
25
Step-by-step explanation:
2 out of 12 means also 1 out of 6.
so, a ratio of 1:6 or a factor of 1/6.
150 × 1/6 = 150 / 6 = 25
so, we expect that out of the 150 sold cars 25 have been red.
Answer:
91 child tickets were sold
Step-by-step explanation:
Let c represent the number of child tickets sold. Then the number of adult tickets sold is (150-c) and the total revenue is ...
5.20c +8.70(150-c) = 986.50
-3.50c +1305 = 986.50 . . . . simplify
-3.50c = -318.50 . . . . . subtract 1305
c = -381.50/-3.50 = 91
The number of child tickets sold that day was 91.

Answer:
17b = w
Step-by-step explanation:
17 times the number of bottles = the number of ounces of water
Then you just plug in the numbers you are given
17(51) = w
17 x 51 = 867
<u>51 bottles of water holds 867 ounces</u>
<u />
17b = (51)
divide both sides by 17
51/17 = 3
b = 3
<u>It would take 3 bottles of water to hold 51 ounces</u>
