I would guess and check. For example, let's say there are 15 yellow marbles. Multiply by 5 and add 3 to get 78, which means it's too much. Then I guessed 8. 8 times 5 plus 3 is 43. Then I added 8 to 43 to see how many total, which would make 51. Now it's to less. Then I guessed 10. Having 10 yellow means 53 white, which is 63 total. Too many again. Then I guessed 9. 9 yellow is 48 white, which makes a total of 57. So therefore, the answer is 48 white marbles.

Answer:
≈ 23.4
Step-by-step explanation:
A = bh
270 = 15b
b = 18
Now you know the two legs, use the Pythagorean Theorem to find the value of the hypotenuse: a² + b² = c²
15² + 18² = c²
225 + 324 = c²
c² = 549
c = √549
