What is the value of x in this figure?

8090 [49]

This is a 45-45-90 triangle and the ratios of the sides are 1 : 1 : sqrt2 where sqrt2 is the length of the hypotenuse ( longest side)

So the measure of x = 12 sqrt2 which is the first choice.

A fruit stand has to decide what to charge for their produce. They need \$10$10 for 44 apples and 44 oranges. They also need \$1

KatRina [158]

Answer:

<em>We can't find a unique price for an apple and an orange.</em>

Step-by-step explanation:

Suppose, the price of an apple is $x$ and the price of an orange is $y$

They need $10 for 4 apples and 4 oranges. So, the first equation will be.......

$4x+4y=10 ........................................(1)$

They also need $15 for 6 apples and 6 oranges. So, the second equation will be........

$6x+6y= 15 ........................................(2)$

Dividing equation (1) by 2 on both sides : $2x+2y= 5$

Dividing equation (2) by 3 on both sides : $2x+2y=5$

So, we can see that both equation (1) and (2) are actually same. That means, we will not get any unique solution for $x$ and $y$ here. Both $x$ and $y$ have <u>"infinitely many solutions"</u>.

Thus, we can't find a unique price for an apple and an orange.
