Your friend drinks 2/3 of a bottle of water. you drink 5/7 of a bottle of water. find the difference of the amount of water left in each bottle

5/21 bottle

Step-by-step explanation:

Your friend drinks 2/3 of a bottle of water, leaving 1/3.

You drink 5/7 of a bottle, leaving 4/7.

Find the difference between 4/7 and 1/3:  

Use the LCD, which is 21:  12/21 - 7/21 = 5/21

The difference between the two amounts of water left in each bottle is 5/21 bottle.

answer: im gonna go with milli

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
