The answer is 68cm^2. Hope this helps!
5 quarters, 15 dimes
q + 10 = d
0.25q + 0.1d = 2.75
0.25q + 0.1(q + 10) = 2.75
0.25q + 0.1q + 1 = 2.75
0.35q = 1.75
q = 5
Check:
0.25(5)+ 0.1(15)= 2.75
1.25 + 1.5 = 2.75
2.75 = 2.75 :)
Answer:
I think it's all of them :)
And what’s the question?????
I would say 504 basing it off of converting 2/3 into 4/6 and used sets of 84 to each be 1/6
