Answer:
1/3x -y +1/3 = w
Step-by-step explanation:
x = 3y + 3w - 1
x - 3y + 1 = 3w
/3 = /3
1/3X - y + 1/3 = w
Answer:
if you mean like you have a algebraic expression and they give you the values of the variables to substitute into the equation, then you just replace the variable with the value for instance
if x = 5
in the equation x + 3 =
then we would replace x with 5 and get 5 + 3 = 8

Answer:
$10 bill = 14 and $20 bill = 16.
Step-by-step explanation:
Given : A cashier has 30 bills, all of which are $10 or $20 bills. The total value of the money is $460.
To find : How many of each type of bill does the cashier have.
Solution : We have given that
A cashier has 30 bills
Let bill of $10 = x .
Bill of $20 = y .
Money of $10 = 10x .
Money of $20 = 20y.
Total bill
x + y = 30-------(1)
10x + 20y = 460-----(2)
On multiplying equation 1 by 10 and subtracting from equation 2.
10x + 20 y = 460
(-)10x +(-) 10 y = (-)300
______________
0 + 10 y = 160 .
On dividing by 10
y = 16 .
Plug y = 16 in equation 1
x + 16 = 30
On subtracting both sides by 16.
x = 30 - 16.
x = 14
Therefore, $10 bill = 14 and $20 bill = 16.
The nearest thousand is 547,000
This is easier to understand with a picture...
We know that a triangle has 3 sides right?
Well, if the perimeter is 39 and there are 3 sides you would divide 39 by the 3 sides
39/3=13
Therefore, one side of the triangle would equal 13
