Answer:
X=24
Step-by-step explanation:
Let a no =X
So
2x+4=52
2x=52-4
2x=48
X=48/2
X=24
So number =24
26.4 minutes. (Just add each of the numbers to get the total, if that helps.)
Let the amount of stamps Mari has be “m”. Since Carlos has 5 more stamps than Mari, Carlos will have 5+m stamps. Amanda has three times as many stamps as Carlos so that will be 3(5+m)=15+3m.
m+(5+m)+(15+3m)=100
5m+20=100
5m=80
m=16
Mari=16
Carlos=16+5=21
Amanda=15+48=63
