We must solve for x by simplifying both sides of the equation, then isolating the variable: 

1/2(x - 2) <span>≤ 1
</span>1/2x - 1 <span>≤ 1
</span>1/2x - 1 + 1 <span>≤ 1 + 1
</span>1/2x / 1/2 ≤ 2 / 1/2
x <span>≤ 4</span>

To prove this, enter 4 or any number smaller than 5 into the equation and solve to see if the statement still stands true.

1. Is it proportional?
astra-53 [7]

Answer:

Y=5(x) Yes it is porportional.

Step-by-step explanation:

So lets look at the graph.

We first have 1x = 5y

Well, that makes it seem like for each x there are 5 y.

Lets see the other values:

2x = 10y

Divide both sides by 2 tog et x alone:

1x=5y

Again, for each x, there are 5y.

This is true for each one:

3x=15y

=

1x=5y

4x=20y

=

1x=5y

5x=25y

=

1x=5y

and finally:

6x=30y

=

1x=5y.

So yes, this is poroportional.

It can be shown as x=5y, since for a single x, there are 5 y's.

Hope this helps!

Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of
Olin [163]

Answer:

153 liters of Petrolyn oil

Step-by-step explanation:

This is a proportion to set this up you do the following:

Nat/Syn = Nat/Syn ; 5/3 = 255/Syn

Then you solve this equation by cross multiplication.

(255*3)/5 = Syn

153 = Synthetic(Petrolyn oil)
