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!

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
