Answer:
<em> 3 years old </em>
Step-by-step explanation:
( 21 + 24 + 18 + 15 + 15 + x ) / 6 = 16
93 + x = 96
x = 3
<em>The person who entered the room is 3 years old.</em>
Answer:
No solutions, 0
Step-by-step explanation:
When you solve a equation and get an answer of n = s (I am just using n and s a placeholders. They that be any number.) where n ≠ s, then there are no solutions to the equation.
I think the answer is a I might be incorrect
It's 96 if you were wondering
The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
<h3>
How to rotate the triangle?</h3>
The coordinates of RST are given as:
R = (5,15)
S = (15,15)
T = (10,5)
The rule of 90° counterclockwise around the origin is:
(x,y) -> (-y,x)
So, we have:
R' = (-15,5)
S' = (-15,15)
T' = (-5,10)
Hence, the image of the triangle when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
