Liz attended class every day since she started school she said she has been in school for about 1000 days what numbers could be the actual nummber of school days if liz roundwd to the nearest ten

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

it is x equals 3   plese mark me really need it

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.
