Her reading quiz, because in order to find a percent dive 17 by 20 (or 20 by 25) and multiply the answer by 100.
X can equal 10,000 because 10,00 divided by 2 is 5000, which is 4 digits
You can use the pythagorean theorem.

Now lets write out what we know.
Shorter leg = x
Longer Leg = x + 7
Hypotenuse = x - 7

Now solve for x

x = 28
Since you know x = 28, which is the shorter leg, you can solve for the rest by just plugging in 28 where x is located. For instance, longer let is x + 7 so
28 + 7 = 35
Answer: Look below
Step-by-step explanation:
2(2x-4y) = 4
1(-4x+6y)= -4
4x-8y=4
-4x-6y=-4
-14y=0
y=0
(Hopefully that helps!!)
