Help easy math question!!!

Answer:

The length of the third side of the triangle is 30.

Step-by-step explanation:

Here is the formula for the Pythagorean Theorem:

$a^{2} + b^{2} = c^{2}$

The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!

We need to multiply 40 times 40 and 50 times 50.

40 times 40, or 40 squared, equals to 1600.

50 times 50, or 50 squared, equals to 2500.

$c^{2} - b^{2} = a^{2}$

Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.

What is the solution to the system of linear equations below?<br> - 2x + 5y<br> 30

avanturin [10]

Answer: Infinite solutions

Step 1: Turn this into y=Mx+b form

The current equation is—

-2x+5y=30

Since we want to get y alone on the left side, let’s add 2x on both sides

-2x+5y=30
+2x +2x
____________
5y=2x+30

Step 2: Again, trying to get y alone, we need to divide 5 on both sides

5y=2x+30
/5 /5 /5
________
y=2/5x+6

Step 3: Now that we know how to find y, substitute that in where y is in the equation

-2x + 5(2/5x+6) = 30
-2x + 2x + 30 = 30
30=30

Seeing that you cannot get a specific answer for y when solving, there is an infinite number of solutions

Hope this is right and it helps comment below for more questions :)
