How do you write 18\42 in simplest form

7 0

You have to find a common number divisible by both numbers of the fraction until you cannot divide the numbers of the fraction any more. So on your problem 18/42 start by dividing both numbers by say 2
18 divided by 2 gives you 9
42 divided by to gives you 21
Then try dividing them again say by 3
9 divided by 3 gives you 3
21 divided by 3 gives you 7
If you try dividing again you will see that you can no longer divide it so 3/7 would be your answer. I hope that helps.

Answer: 320 triangles

Step-by-step explanation: Triangles can be drawn utilizing one side of the polygon. In the event that we take one side, at that point there are a add up to of 16 triangles that can be drawn and we have 20 sides. So, add up to 20×16=320 triangles.

The equation for line g is given by 5y=2x-20. Suppose line g is parallel to like r and line e is perpendicular to line g. Point

Sounds as tho' all three lines are parallel. Is that correct?

If so, all three lines have the same slope!

What is the slope of 5y=2x-20 ? Solving for y, y = (2/5)x - 4

The slope is (2/5).

Now find the equation of the line with slope (2/5) that passes thru (10,-8).

It is y - [-8] = (2/5)(x - 10).

We can simplify this, with the result y + 8 = (2/5)x - 4. This, in turn, can be simplified to y + 8 = 2x/5 - 4, or y = 2x/5 - 12. Mult. all terms by 5 to eliminate the fraction:

5y = 2x - 60

Note how this has the exact same form as the given 5y = 2x - 20, EXCEPT that the constant at the end is different.

5y = 2x - 60 and 5y = 2x - 20 are parallel lines with the same slope but different y-intercepts.
