Answer:
Use both methods to calculate the sale price of an item that costs $140 and has a discount of. 40%. 140 x.40 = 56. 140-56 +84. 140x.60 = $84.

I believe it’s 16/24 and 20/30
Answer:
x= −1/3 y+5/3
Step-by-step explanation:
Let's solve for x.
y=−3x+5
Step 1: Flip the equation.
−3x+5=y
Step 2: Add -5 to both sides.
−3x+5+−5=y+−5
−3x=y−5
Step 3: Divide both sides by -3.
−3x

Determine the additive inverse of each
The rule of additive inverse is as follows;
- For any positive number (n), the additive inverse is (-n)
- And for any negative number (-n), the additive inverse is (n)
Using the above, the solution is as follows:

Rule: <em>6 becomes -6 and - (-3) becomes +(-3)</em>
So, the additive inverse is 

<em />
Rule: <em>-6 becomes 6 and -3 becomes 3</em>
So, the additive inverse is 

Rule: <em>6 becomes -6 and -3 becomes 3</em>
So, the additive inverse is 

Rule: -<em>6 becomes 6 and -(-3) becomes +(-3)</em>
So, the additive inverse is

total = 19.99 + 0.10(x-300) + 0.25y
x = 375
y=54
total = 19.99 +0.10(375-300) +0.25(54)
total = 19.99 + 0.10(75) + 0.25(54)
total = 19.99 + 7.50 + 13.50
total = $40.99
