X+2x=63 3x=63 x=21 21*2 is 42 so long is 42 and 21 is short
Answer:
4,6,14,18, and 20
Step-by-step explanation:
Simple,
1/2 of 60
re-write it as 0.5 of 60 aka 0.5*60
which is 0.5*60=30
Do the same with 1/2 of 24.
0.5 of 24
0.5*24=12.
Thus, it's not the same because they are different numbers and different number give you different answers.
30% of 250 can be written as 0.3 * 250:
0.3(250) = 75
30% of 250 is 75. Is this what you mean by "compute with percents?"
