h(t) = -16t * (t + 5)

- 6x - 12 + 2x = 28

Hello Guest!

What is 131.9468915 as a fraction?

131.9468915

= 1319468915 /10 000 000

Hello Guest!

What is y + 2 = -10(x – 4)?

y + 2 = -10 (x - 4) is a function of x.

y + 2 = -10 (x - 4)

y = ƒ(x) = - 10x + 38

Hello Guest!

What is 3 3/4 divided by 2 1/2 divided by 1/2?

[(3 +  3/4) / (2 + 1/2)] / (1/2)

= [(15/4) / (5/2)] / (1/2)

= (30/20) / (1/2)

= 60/ 20

= 3

3/4 divided by 2 1/2 divided by 1/2 = 3

Hello Guest!

1-1/2x=3/4x+1? Explain.

1 - 1 / 2x = 3 / 4x + 1        [ both sides - 1

- 1 / 2x = 3 / 4x                [ both sides reciprocal

- 2x = 4x / 3                     [ both sides + 2x

0 = 2x + 4x / 3

0 = (6x + 4x) / 3               [ both sides * 3

0 = 10x                            [ both sides / 10

x = 0  not correct !

Sample:

- 1 / 2x = 3 / 4x 

- 1 / 2*0 = 3 / 4*0

x is undefined
