Whats the fraction for 20 ft in 45 sec

The fraction would probably be the speed as well so here:

You do 20/45 which simplifies to 4/9

So the speed/fraction for this problem is 4/9 (feet per second)

P.S. I'm sorry if this is hard to understand

20ft = 45 sec

divide both by 5 you get

4ft = 9 sec

4ft every 9 seconds would be your answer unless you want a fraction.

1 ft = 2 1/4 seconds

I hope I helped. If you think I'm worthy a Brainliest answer would be nice :D

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
