Find the value of X so that the function has the given value.

q(x) = 1/2x - 3 ; q(x) = -4

well from the given functions of x we can say

1/2x-3=-4

=> 1/2x = -1

=> x = -2

so value of x = -2

hope it helps

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
