6. Talayah bought two journals. The second journal cost $12 more than the price of
the first journal. If she spent $30 on both,
how much was the second journal?
A. $12
B. $16
C. $20
D. $28

C. $20

Step-by-step explanation:

Lets make our equation. "x" will be our first journal, and "4/5x + 12" will be our second journal. So our equation is: x + 4/5x + 12 = 30

Subtract 12 from each side: x + 4/5x = 18

Combine like terms : 1 4/5 x = 18

Divide each side by 1 4/5 : x = 10

Plug in x for the journals-

1 = 10

2 = 4/5 of 10 = 8 + 12 = $20

I hope this helped, please mark Brainliest, thank you!

what do you mean by fog

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
