Answer:
There is a picture below of the number line with the numbers, plotted.
Step-by-step explanation:
For the 2 3/8, you would simply go to 2 and count 3 to the right becuase there are 8 points for each whole number to the next. It's pretty hard to explain sorry. For 1 3/4, you would make the denominator 8, so multiply it by 2. When we do this, we multiply both the numerator and denominator. What is done to one must be done to the other. 3*2 to get 6. 4*2 to get 8. So, 3/4 becomes 6/8. Now, we can go to 1, and count 6 points to the right to get to 1 3/4.
Answer:
<h2>30 mm</h2>
Step-by-step explanation:
The formula of an area of a circle:

<em>r</em><em> - radius</em>
<em />
We have

Substitute:
<em>divide both sides by π</em>
<em>use π ≈ 3.14</em>

The diameter <em>d = 2r</em>.
Therefore

Answer:
A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It must be a solution for both to be a solution to the system. Hope this helps.
