Answer:
-5x - 7y
Step-by-step explanation:
You paid $4.76 total for 7 notebooks. To figure out how much each individual notebook cost, you divide the total cost by the number of things you bought, so
Cost of One Notebook = Total Cost of Notebooks / Number of Notebooks = $4.76 / 7 = $0.68
This is the unit rate.
To buy three notebooks, you just calculate the total cost of three notebooks at this price point, so
Cost of Three Notebooks = Cost of One Notebook * 3 Notebo0ks = $0.68 * 3 = $2.04
Answer:
(-1,1)
Step-by-step explanation:
Answer:
8x + 6 = 3
Step-by-step explanation if solving for x
Simplifying
8x + 6 = 3
Reorder the terms:
6 + 8x = 3
Solving
6 + 8x = 3
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 8x = 3 + -6
Combine like terms: 6 + -6 = 0
0 + 8x = 3 + -6
8x = 3 + -6
Combine like terms: 3 + -6 = -3
8x = -3
Divide each side by '8'.
x = -0.375
Simplifying
x = -0.375
