Let
x---------> time in minutes used by Eric to study
y---------> time in minutes used by Kendra to study
z---------> time in minutes used by Geraldo to study
we know that
x=3y------> equation 1
x=0.5z
z=2x--------> equation 2
y=20 minutes --------> equation 3
substitute equation 3 in equation 1
x=3*20=60 minutes
find the value of z in equation 2
z=2*60=120 minutes
therefore
<u>the answer is</u>
The time in minutes used by Geraldo to study was 120 minutes
Answer:
i think it is same let me know
You got me screwed I don't even know how to work out the problem
I'm going to assume you meant 27 because three odd integers added together can't be even.
The three integers are expressed as x, y and z:
x+y+z=27
x+2=y
y+2=z
x+4=z
x+x+2+x+4=27
x+x+x+2+4=27
3x+6=27
3x=21
x=7
y=9
z=11
7+9+11=27
The numbers are 7, 9 and 11
Hope this helps.
