The proportion would be 1/3 and x/9. Cross multiplication creates 3x=9. Divide both sided by three, and there are 3 trombones in the orchestra.
Answer:
c
Step-by-step explanation:
because 2 + 15 = 17, 8 + 15 = 23, 10 + 15 = 25
Given:
The polygon in the given figure are similar.
To find:
The missing side length.
Solution:
We know that the corresponding sides of similar figures are proportional.
The given polygons are similar, so the their corresponding sides are proportional.

So, the missing values in the equation of proportion are 15, 40, 32 respectively.
On solving the above equation, we get




Therefore, the value of x is 12.
X=y-bm is the answer you are looking for
16. i’m pretty sure cause the ratio would be 42/24 28/x if you divide PQ by LM, the answer is the same number you would use to divide LM to get MN and finish your ratios
