Add $372+ $1513 that should give you the average for juniors
The answer is y=16
You must first combine like terms (8y-3y = 5y)
Then you must subtract 7 on both sides to cancel out the 7
You are left with 5y=80
Divide 5 by both sides to get you answer 80/5 = 16 so y=16
The student should have phrased it to be "the difference between the product of 5 and y and 15", as the way the student writes it implies that 5y is being subtracted from 15 instead of the other way around.
Answer:
You can use a variable expression to describe a real world situation where one or more quantities have an unknown value or can change in value. To write a variable expression for a real world situation: Figure out which quantity in the situation is unknown and define a variable to represent the unknown quantity.3
Answer:
x-axis =
y-axis =
Line x =3 :
Line x = 6 :
Step-by-step explanation:
Given lines : y = √x
y = 0
x = 3
To determine the volumes generated we will use the disk method for each of the lines,
attached below is the detailed solution for line x =3 , same procedure will be repeated for each value of x and y to obtain the given results
The volume generated ( x axis )
=
volume generated ( y _axis )
=
Volume about x = 3
=
Volume about x = 6
=
