The answer: they are 11,12,14.
Well the first thing you need to do is set up a proportion.
8 girls 56 girls
-------- = -----------
7 boys x
Now what we have to do is find out what we multiplied by 8 to get 56.
Simply divide.
56 ÷ 8 = 7
So, we figured out that the magic number is 7!
So we multiply the boy number by 7
7 x 7 = 49
So this means that there are 49 boys on the field trip.
Answer:
25x = 75 (Because they are alternate interior angles)
=> x = 75/25
=> x = 3
So, x = 3
Because 25x is equal to 75, the two lines (u and v) are parallel
Answer:

Step-by-step explanation:
Take the total, 50.35, and subtract 19.95:

Therefore, Tony bought 8 markers.
Answer:
Step-by-step explanation:
