Mathematics
1 answer:

<u>Answer:</u>

<h2>18.38</h2>

<u>Explanation:</u>

since this triangle is a right-angled triangle and one its angles equals 45° then it's an <u>isosceles right triangle</u> which means that the side opposite 45° <em>(the side to the left)</em> is equal to 13 too.

so according to pythagoras theorem c = √(a²+b²)

x =√(13²+13²)

x = √(169+169)

x = √338

x ≈ 18.38

<em>note:</em><em> in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!</em>

Tom has three times as many pencils as pens but has a total of de 100 writing utensils. How many pencils and pens does toms have
IrinaVladis [17]

Answer:

Tim has 75 pencils and 25 pens

Step-by-step explanation:

To solve this create a system of equations. To do so, first create an equation for the total number of utensils that he has. Let x equal the number of pencils and y equal the number of pens.

x+ y = 100

Now make one for the comparison of the two and solve for the constant.

x = 3y

x - 3y = 0

Now to solve the system, multiply the second equation by -1 and add them together.

x + y = 100

-x + 3y = 100

-----------------

4y = 100

y = 25

Now that we have the number of pens, find the number of pencils using an equation.

x + y = 100

x + 25 = 100

x = 75
