Let the hypotenuse be x then,
Using the pythagoras theorm,
10^2 + 24^2 = x^2 (alt^2 + base^2 = hypo^2)
100 + 576 = x^2
676 = x^2
Therefore x= square root of 676 = 26
Hope this helped! :D
Make x=0 in the second equation, giving you y=-3. If you plug that in to the top equation you would get x-3(-3)=-19, x+9=-19,x=-28.

Step-by-step explanation:
First, find 10%
To find 10% of a number, just take off one zero, or move the decimal point back once.
So let's do #1
100% of 50
Find 10% of 50 = 5
Now we've found 10%, we still have 40% left (because it's 50%; 50-10=40)
Multiply 5 by 10
5 × 10 = 50
Let's do #7
60% of 70
Find 10% of 70 = 7
Multiply 7 by 5 (because its 60% and we've done 10%; 60-10=50)
7 × 5 = 35
:) hope i helped!
