Fifty-five and twelve hundreths
39x-3y=21
-3y=21-39x
(subtract both sides of the equation by 39x and divide both sides by -3)
y=-7+3x : would be the equation for y.
Answer:
The simplify form of the provided expression is:
Step-by-step explanation:
Consider the provided expression.

Now simplify the above expression as shown below:

as 16/8 = 2
Now again simplify the above expression.
as 2/6 = 1/3
Now, multiply the whole expression with 3.
Hence, the simplify form of the provided expression is:
Answer:
Is this the system of equations?
Answer:
They will expect the ratio below:
x/20 = 160/8, with x: population
Then
x = 20x160/8 = 400
