Answer:
Solution given:
we have
m<PTQ=m<RTS
x+20=3x+12.
20-12=3x-x
x=

now
16.m<PTQ=x+20=4+20=24°
17.
again
m<PTR+m<PTQ=180°[supplementary]
so
m<PTR=180°-24°<u>=1</u><u>5</u><u>6</u><u>°</u><u> </u><u>i</u><u>s</u><u> </u><u>your</u><u> </u><u>answer</u>
- (- 4) + 8 is the same as doing - 1(- 4) + 8 or - 1 x (- 4) + 8
Any negative times a negative becomes a positive so we just do 1 x 4 = 4.
4 + 8 = 12.
Your answer is 12.
Answer:
I'm pretty sure it's number 2 although I think you meant milk spoiling and that's a chemical change
Cubic root of 8 is 2
Cubic root of 27 is 3
So the fraction will be -2/3
