Abag contains green marbles and blue marbles, 24 in total. the number of green marbles is 9 less than 2 times the number of blue marbles. how many green marbles are there?

13

Step-by-step explanation:

A bag contains green marbles and blue marbles, 24 in total: g + b = 24

The number of green marbles is 9 less than 2 times the number of blue marbles: g = 2b - 9

Substitute g = 2b - 9 into g + b = 24

2b-9+b=24

3b=24+9=33

b=11

Substitute b = 11 into g = 2b - 9

g=22-9 = 13

a) 32pie square meters

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
