I think that you should try to involve yourself in their interests. Find a way to play with them because, as it seems, you want to maintain a friendship with this person, but want to be more involved in their life. I hope this helps <3
Answer:
#1: x = 3; #2 c = 1/2; #3 = x = 22; #4 is correct (x = -8)
Step-by-step explanation:
for the first equation everything was right until 22x = 66
after
22x = 66
you must divide everything by 22
x = 3
that is for #1
for the second equation you copied down the question wrong
the negative is still there
6c - 8 - 2c = -6
combine 6c and -2c
4c - 8 = -6
the negative remains on the 8
add 8 to both sides
4c = 2
divide 4 to both sides
c = 2/4 or just 1/2
for the third equation you must first combine like terms
-3x + 25 + x + 21 = 2
combine -3x and x & 25 and 21
-3x + x = -2x
25 + 21 = 46
-2x + 46 = 2
then subtract 46 from both sides
-2x = -44
now divide both sides by -2
x = 22
that is your answer
number four should be correct
The general expression would be:

In an organism that is 20,000 years old (t = 20000), we would expect:

This menas there would be around 8.898% of carbon-14 remaining in the organism.

Answer: 54 cm^2
Step-by-step explanation:
The area of a triangle is base*height/2.
To find the missing side of this triangle we can use pythagorean theroem. Let the unknown side = x
15^2 = 12^2+x^2
225 = 144+x^2
x^2 = 81
x = 9
Area = BH/2
Area = 9*12/2
Area = 54 cm^2
