Answer:
x = 7/
or 4.949747468
Step-by-step explanation:
45-45-90 triangles have a specific pattern.
The smaller sides are x, & the hypotenuse is 
With this knowledge, we know we have to divide the hypotenuse by
to get the smaller sides, so we divide 7 by the
to find x.
Since they tell us that Q is the midpoint you now understand that the line is split evenly.
PQ=QR
2x+3=3x-2
2x+5=3x
x=5.
It's a simple linear equation in 'y'. There is only one number that 'y' can be
that will make the equation a true statement. That number is called the
'solution' to the equation. Here's one way to find it:
You said that <u> 2 = y/5 - 8</u>
Add 8 to each side: 10 = y/5
Multiply each side by 5: <em> 50 = y</em>
