3(x+2) -x < 8
Simplify the left side:
3x + 6 -x < 8
2x + 6 < 8
Subtract 6 from both sides:
2x < 2
Divide both sides by 2:
X < 1
x squared plus 9 plus 53. x squared plus 62. square root both sides. x equals 7.9 or 8.
Hope this helps.
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
75% of the numbers lie below or on the third quartile, and the remaining 25% lie on or above it.
I think the correct answer is C. because each if forming a right triangle when you trace it.
