Step-by-step explanation:
When using the Elimination method, you eradicate one pair of variables so they are set to zero. It does not matter which pair is selected:
{2x - 3y = 9
{⅖[−5x - 3y = 30]
------------------------------------------------------------------------------------------
{x - 2y = 10
{⅔[x + 3y = 5]
_______________________________________________
{y = −3x + 5
{−⅜[y = −8x + 25]
------------------------------------------------------------------------------------------
{y = −x + 1
{¼[y = 4x - 14]

Answer:
Y = 10.25 or 10.247
Step-by-step explanation:
Alright So use the Formula A^2 + B^2 = C^2
You have one leg and the hypotenuse so first you are going to find 19 ^2 = 361.
Next, you need to find 16^2 = 256.
Last but not least, you subtract the leg from the hypotenuse, which equals 361-256=105
Finally, you take 105 and find its square root.
And depending on how far you round it down, your answer would be 10.25(that is in tenths), or 10.247(which is rounded to hundredths)
Hope this helps!
<span>To find what percent one number is of another number, write the two numbers as a fraction, with the whole as the denominator. Then find an equivalent ratio with a denominator of 100 and write that ratio as a percent.</span>
Answer:
The second equation can be used
Step-by-step explanation:
Just plug in the values and the equation should look like this 8^2 + b^2 = 12^2
12 is the hypotenuse to plug that into c
and 8 is just a leg so you can either put it in a or b
