Answer:
3 vegetable trays, 2 sandwich trays
Step-by-step explanation:
I'm not quite sure what we're supposed to find, but if we were to find how many of each we can buy with $120 it would be 3 vegetable trays and 2 sandwich trays.
20 + 20 + 20 = $60
30 + 30 = $60
60 + 60 = $120
Find a right angle and multiply each side and then add them :) hope this helps
220= 45*x. I hope you are satisfied with my answer.
Answer:
Step-by-step explanation:
Let x be the original number.
x - 15 - 1/2(x - 15) - 10 = 12
x - 15 - 1/2 x + 7.5 - 10 = 12
1/2x - 25 + 7.5 = 12
1/2x - 17.5 = 12
1/2x = 27.5
x = 55
