Answer:
x-9 = 16
Step-by-step explanation:
Given: Samantha donated 9 t-shirts to charity and left with 16 t-shirt.
Let x be the total number of t-shirt Samantha had originally .
As 9 t-shirt been donated to charity out of her total t-shirt
∴ equation will be
Now, she is left with 16 t-shirt
so, ![x-9 = 16](https://tex.z-dn.net/?f=x-9%20%3D%2016)
∴ The equation to find x or total number t-shirt samatha had originally is ![x-9= 16](https://tex.z-dn.net/?f=x-9%3D%2016)
Answer:
y= 28/17
x= 57/17
Step-by-step explanation:
5x + 2y = 22
-2x + 6y = 3
(2)(5x + 2y = 22)→ 10x + 4y = 44
(5)(-2x + 6y = 3)→ -10x +30y = 15
Add this last eq → 34y=56 → y= 28/17
Replace this in any equation
-2x + 6(28/17) = 3 → x= - (54/17-168/17)/2 = 57/17

XY = 17.
Because YW is a perpendicular bisector, we can say that TW and WZ are both equal to 3. It tells us that XZ is 12, so that means that XW must be 12+3 which equals 15.
It also tells us that YW is 8. So we can use the Pythagorean Theorem to find the hypotenuse of Triangle XWY. Thus,
![15^{2} + 8^{2} = XY^{2}](https://tex.z-dn.net/?f=%2015%5E%7B2%7D%20%20%2B%20%208%5E%7B2%7D%20%3D%20%20XY%5E%7B2%7D%20)
To solve this equation, square and add both of the terms on the right like this:
![289 = XY^{2}](https://tex.z-dn.net/?f=289%20%3D%20%20XY%5E%7B2%7D%20)
And then take the square root of both sides. Your final answer should be:
XY = 17.
