To prepare for a math test eric study three times as long as kendra and 1/2 as long as geraldo. how long did geraldo study if kendra studied for 20 minutes?

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

the answer is

The time in minutes used by Geraldo to study was 120 minutes

i not know

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
