Im not quite sure but i think the unit rate is 150. Hope this helps!!
Answer:
Step-by-step explanation:
![(\sqrt{z} +\sqrt{22})(\sqrt{z} -\sqrt{22})=35](https://tex.z-dn.net/?f=%28%5Csqrt%7Bz%7D%20%2B%5Csqrt%7B22%7D%29%28%5Csqrt%7Bz%7D%20-%5Csqrt%7B22%7D%29%3D35)
Subtract both sides from 35
![(\sqrt{z}+\sqrt{22} (\sqrt{z} -\sqrt{22})-35=35-35](https://tex.z-dn.net/?f=%28%5Csqrt%7Bz%7D%2B%5Csqrt%7B22%7D%20%28%5Csqrt%7Bz%7D%20-%5Csqrt%7B22%7D%29-35%3D35-35)
Simplify:
![(\sqrt{z})^{2} -57=0](https://tex.z-dn.net/?f=%28%5Csqrt%7Bz%7D%29%5E%7B2%7D%20-57%3D0)
Factor
=0
![\sqrt{z} +\sqrt{57}=0 or \sqrt{z} -\sqrt{57}=0](https://tex.z-dn.net/?f=%5Csqrt%7Bz%7D%20%2B%5Csqrt%7B57%7D%3D0%20%20%20%20or%20%20%20%20%5Csqrt%7Bz%7D%20%20-%5Csqrt%7B57%7D%3D0)
![\sqrt{z} +\sqrt{57} =0: No Solution for Z](https://tex.z-dn.net/?f=%5Csqrt%7Bz%7D%20%2B%5Csqrt%7B57%7D%20%3D0%3A%20No%20Solution%20for%20Z)
![\sqrt{z} -\sqrt{57} =0: z=57](https://tex.z-dn.net/?f=%5Csqrt%7Bz%7D%20-%5Csqrt%7B57%7D%20%3D0%3A%20z%3D57)
Your answer will be z=57
and No solution
Answer:
Part A: The price of 1 pound of potatoes is 1 dollar and 25 cents (1.25) because 5 / 4 is 1.25 and that's 1 pound
Part B: The ordered pair (10, 8) represents that 10 punds of potatoes cost 8 dollars

Answer:
x = 35
Step-by-step explanation:
Since they are vertical angles, the angles are congruent and therefore you can set them equal to each other.
4x + 20 = 3x + 55
Have x on one side of the equation by subtracting 3x from both sides.
x + 20 = 55
Subtract 20 from both sides of the equation.
x = 35
