Do the ratios 4/2 and 10/5 form a proportion? Yes or no
mars1129 [50]

Answer:

These are both 20 so that means that this is proportional, yes.

Step-by-step explanation:

Hi.

To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.

Here is how we do this.

\frac{4}{2}    \frac{10}{5}

So basically what we are doing is multiplying across in a diagonal direction.

Diagonal meaning like a slash / .

So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.

Do the same for the 2 and the 10.

So we have to multiply :

4 x 5

2 x 10

=

20

These are both 20 so that means that this is proportional, yes.

Hope this helps.

If you have any questions or concerns feel free to message me.

The perimeter of the triangle is 13 inches. What is the length of the shortest side?
netineya [11]

Answer:

shortest side = 3 in

Step-by-step explanation:

Sum the 3 sides and equate to 13, that is

x - 5 + 6 + \frac{x}{2} = 13, that is

x + 1 + \frac{x}{2} = 13 ( subtract 1 from both sides )

x + \frac{x}{2} = 12 ( multiply through by 2 to clear the fraction )

2x + x = 24

3x = 24 ( divide both sides by 3 )

x = 8

Thus

x - 5 = 8 - 5 = 3 and \frac{x}{2} = \frac{8}{2} = 4 , then

The shortest side is x - 5 = 3 in
