Answer:
G. 12
Step-by-step explanation:
Rachel = x
Trina = y
x = 2y - 6
x = (2x9) - 6
x = 18 - 6
x = 12
4^x + 6^x = 9^x
4^x + 6^x - 9^x = 0
2^2x + (2×3)^x - 3^2x = 0
2^2x + 2^x×3^x - 3^2x = 0
(⅔)^2x + (⅔)^x - 1 = 0
let t = ( ⅔)^x
t² + t - 1 = 0
t = (-1+√5 ) / 2
(⅔)^x = (-1+√5 ) / 2
x = Log base ⅔ ((-1+√5 ) / 2 )
x = 1.18681

a is the answer hope this help:D
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
1+9+5+0+8+1+7+4+1=36
then divide by the total number of digits which is 9

For each candy bar it would be 3 dollars each so
The four candy bars are a total of 12$ it self plus the 4 dollars for the soft drink so 12+4 is 16
So 3$ each candy bar
