Answer:
E. is 103 degree.
It's a vertical angle.
F. is 77 degree
the e and f makes a 180 degree. 180-103(aka e) = 77 degree
D. is 90 degree. it's perpendicular.
Answer: x= -6
Let’s first rewrite the equation
3x-(2x-3)=2x+9
Now now distribute the -1•2x and the -1•-3
3x-2x+3=2x+9
Let’s now combine the like terms on the left side
x+3=2x+9
To get x alone on the left side, subtract it on both sides
3=x+9
To get your final answer, subtract 9 on both sides
-6=x
And that’s your answer for x! Hope this helps comment below for more questions :)
Answer:
The bacteria took 1 hour and 40 minutes to fill the first bottle and it took only 10 minutes to fill 3 more. This is because of the amount of bacteria, for the first bottle there were only a few so it took them time to grow and multiply but once there were a lot the process starts to get faster. Think of it like this if you have 1 bacteria it will multiply into 2 bacteria. The 2 will multiply into 4, then 8, 16, 32, 62, 124 and so on. Do you notice how the numbers are getting bigger every time? Each number is being multiplied by 2 so the growth rate speeds up very quickly, which is why it took the bacteria 1 hour and 40 minutes to fill the first bottle and only 10 minutes to fill the other 3.
(I'm not sure but this is my theory)
Answer:
x = 15
LM = 18
MN = 18
LN = 18
Step-by-step explanation:
To find x:
x + 3 + 2x - 12 + 33 - x = 54
2x + 24 = 54
2x = 54 - 24
2x = 30
x = 15
LM:
x + 3
15 + 3
18
MN:
33 - x
33 - 15
18
LN:
2x - 12
2(15) - 12
30 - 12
18
