9d - 5 = 4d + 35
9d (-4d) - 5 (+5) = 4d (-4d) + 35 (+5)
5d = 40
5d/5 = 40/5
d = 8

I believe it is 20 since I did 4+4+4+4+4 =20 since each shirt has 4 mixes it could have with the pants. Hope I helped
The formula is x1+x2 divided by 2 and y1+y2 divided by 2.I hope this is what you where looking for
Answer:
25 boys.
Step-by-step explanation:
To solve this problem, first add the two parts of the ratio. 9 + 5 = 14. Then divide 70 by 14 to get 5. Since the total is 5 times the ratio total, multiply both sides of the ratio by 5. The result is 45 : 25. If you add them together, you get a total of 70. Therefore, there are 25 boys in the class.
