Mathematics
1 answer:

Answer:

H

Step-by-step explanation:

Let a represent Ann's height, and let j represent Jay's height

Break up the sentence into the key parts.

"The difference between Ann's and Jay's heights" "is" "half of Jay's height"

"The difference between Ann's and Jay's heights" becomes the expression:

         a - j

"is" is math means an equal sign '='

"half of Jay's height" becomes the expression: (1/2)j

Put the 3 parts together and get the equation:

a - j = (1/2)j,

Since all the equations in the answer choices are in terms of a, solve the above equation for a...

a = (1/2)j + j, which is answer H

Answer for the square root(5x-9)+1=x
Evgen [1.6K]

\bf \sqrt{5x-9}+1=x\implies \sqrt{5x-9}=x-1\implies 5x-9 = (x-1)^2 \\\\\\ 5x-9=\stackrel{\mathbb{FOIL}}{x^2-2x+1}\implies 5x=x^2-2x+10\implies 0=x^2-7x+10 \\\\\\ 0=(x-5)(x-2)\implies x= \begin{cases} 5\\ 2 \end{cases}
