Answer: A. . . . . . . . . .

I can’t do that check mark thing so I’ll use ! instead.

!12+2!8-12!2

!12 2!8

2!3+2!8-12!2

!8 2!2

2!3+2x2!2-12!2

2x2!2 4!2

2!3+4!2-12!2

2!3+(4!2-12!2)

2!3-8!2

Answer:

x = -8

Step-by-step explanation:

I will show each step algebraically. If you need further explanation, feel free to ask questions :)

$\frac{x}{2} +7=3\\$ Rewrite

$\frac{x}{2} =-4$ Subtract 7

$x =-8$ Multiply by reciprocal (2/1)

I hope this helps!

Answer:

x = 10°

Step-by-step explanation:

Step 1:

92° + x° + 78° = 180° Supplementary Angles

x° + 170° = 180° Combine Like Terms

Step 3:

x° = 180° - 170° Subtract 170° on both sides

Two points are selected randomly on a line of length 32 so as to be on opposite sides of the midpoint of the line. In other word

Paladinen [302]

Solution :

Let us consider the squares be $[1, 16] \times [16, 32]$

If x ranges from the 0 to 16 and the y ranges from 16 to 32, we see that the boundary of the region $y-x \geq 9 \text{\ is}\ y - x = 9$ which goes from the $(7, 16 ) \text{ to}\ (16, 25)$ .

And so it is easier to find the area of region where $y-x \leq 9$ . This is the triangle with points $(7,16),(16,25) \text{ and}\ (16,16)$ as its vertices.
