he bought 34 pencils which I suppose aren't already sharpened
so if he sharpens 16 of them just subtract 16 from 34 (34-16) which equals 18
so the ratio would be 16:18
but if u need to simplify it would be 8:9
The pressure is 39 Pa if the volume is expanded to 168L and the pressure, P, of a gas varies inversely with its volume, V.
<h3>What is a proportional relationship?</h3>
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
We have:
The pressure, P, of a gas varies inversely with its volume, V.
P ∝ 1/V
P = k/V
k is the constant.
If P = 126 Pa and V = 52 L
126 = k/52
k = 6552
P = 6552/V
Plug V = 168 L
P = 6552/168 = 39 Pa
Thus, the pressure is 39 Pa if the volume is expanded to 168L and the pressure, P, of a gas varies inversely with its volume, V.

Expand
5x - 5 + 3 = 7x + 7
Simplify 5x - 5 + 3 to 5x - 2
5x - 2 = 7x + 7
Subtract 5x from both sides
-2 = 7x + 7 - 5x
Simplify 7x + 7 - 5x to 2x + 7
-2 = 2x + 7
Subtract 7 from both sides
-2 - 7 = 2x
Simplify -2 - 7 to -9
-9 = 2x
Divide both sides by 2
-9/2 = x
Switch sides
<u>x = -9/2</u>

Is the equation like this
If the equation of a line is in standard form, the easiest method to graph the line is by finding intercepts. Remember that at the y-intercept, the x coordinate is equal to 0, and that at the x-intercept, the y coordinate is equal to 0. To find the y-intercept, set x equal to 0 and solve for y.
I hope this helped!
