MAXImum [283]2 years ago
8 0

Answer:

Step-by-step explanation:

( 2√x - 3√y ) /(√x + √y )

= [(2√x-3√y)(√x -√y)]/[(√x+√y)(√x-√y)]

= [2x +2√xy -3√xy -3y]/[ (√x)² -(√y)²]

=[2x - √xy -3y ] / ( x - y )

I hope this helps you.

ruben is buying bricks for a project. he knows that 5 bricks weigh 26 1/4. he wants to know the weight of 24 bricks
Phoenix [80]

Answer:

the weight of 24 bricks is :

124\frac{4}{5}

Step-by-step explanation:

26\frac{1}{4} =26+\frac{1}{4} =\frac{26\times 4}{4} +\frac{1}{4} =\frac{105}{4}

It is clear that there is a proportional relationship between the number of bricks and their weights then :

\frac{26\frac{1}{4} }{5} =\frac{x}{24} \Longrightarrow \frac{\left( \frac{105}{4} \right)  }{5} =\frac{x}{24} \Longrightarrow \frac{26}{5} =\frac{x}{24}

\Longrightarrow x=\frac{26\times 24}{5} =\frac{624}{5} =124\frac{4}{5}
