Mabel spends 4 hours editing a 3 minute video. she edits at a constant rate. how long does mabel spend to edit a 9 minute video?
she spends 4 hours on a 3 minute video
so there are 60 minutes in an hour
4 hours with 60 minutes- 4x60=240
so she spent 240 minutes on a 3 minute video
3 divided by 240
3/240= 0.0125
so her constant rate is 0.0125 minutes an hour
so divide 9 minutes by her constant rate
9/0.0125 = 720
so she spends 720 minutes on a 9 minute video.
divide 720 by 60 since there are 60 minutes in an hour
720/60 = 12
so she spends 12 hours on a 9minute video
-9(2)+4=-16 you do -9 times 2 which is -18 then you subtract that to 4 which you get -16. hope this helps!
Answer:
x = 139º
Step-by-step explanation:
A line = 180º
180º - 41 º = 139º
As we know these two lines mean | | a modulus sign. The modulus symbol is sometimes used in conjunction with inequalities. A modulus sign in simple words just ignores the sign and gives us the absolute value.
For example in this case the modulus gives us 4 x 2 - 3. As you can see the modulus sign has ignored the original negative signs with the numbers.
So after evaluating the equation the answer comes out to be 8 - 3 which is equal to 5.
First you would need to solve x.
2x+x+14+x-38=180
4x-24=180
4x=204
x=51
Now plug in the x for all three angle measures.
2(51)=102 degrees
51+14=65 degrees
51-38=13 degrees
Final answer is 102 degrees, 65 degrees, 13 degrees
