from both sides of the equation.
Answer:
Apply the distributive property.
6 ⋅ 5 + 6 (-3x) = -4 x - 12
Multiply
6 by 5 . 30 + 6 (-3 x) = - 4 x - 12
Multiply
− 3 by 6 . 30 - 18 x = - 4 x - 12
Add
4 x to both sides of the equation.
30 - 18 x + 4 x = - 12
Add
− 18 x and 4 x . 30 - 14 x = - 12
Subtract
30
from both sides of the equation.
- 14 x = - 12 - 30
Subtract
30 from
− 12 . - 14 x = - 42
x = 3

Answer:
$5.25 Dollars
Step-by-step explanation:
I know that if you divide 21 by 3 you get 7. So, 2/3 of 21 is 14. He spent 14 dollars at the music store. This means that he has 7 dollars left. From here he spend 1/4 of 7 dollars on a drink. 1/4 of 7 is $1.75. This means that he has 5.25 dollars left after he bought the drink! :)

Answer:
Discount = $30, Final price = $90
Step-by-step explanation:
25% is one quarter. 120/4=30
One quarter of 120 is 30, so - 30 would give discounted price of $90.
Similarly you could think of it like the discounted price is 75% of the original one and do 120x0.75=90 to find 75% of 120.
