Rudiy27

Answer:

There would be 40 red gumballs

Step-by-step explanation:

Since, out of 40 gumballs there are 8 red gumballs,

So, the ratio of red gumballs and total gumballs = $\frac{8}{40}$

$=\frac{1}{5}$

Now, let there are x red gumballs in 200 gumballs,

The ratio of red gumballs and total gumballs = $\frac{x}{200}$

$\implies \frac{x}{200}=\frac{1}{5}$

$x =\frac{200}{5}=40$

Hence, the possible number of red gumballs in the jar would be 40.

PLEASE HELP RN

yulyashka [42]

Step-by-step explanation:

y = -9x - 45 -5

y = -9x - 50

slope = x coefficient = -9

we can use the point where

x = 0

y = -50

P1 (0, -50)

and when y = 0

-9x = 50

x = -50/9

P2 = (-50/9 , 0)
