Answer: Following the rules of PEMDAS, you want to divide both sides of the equation by -2. This would change your equation to x+3=5. Then you move your constant to the right-hand side and change its sign. Your equation is now x=5-3. subtract 5-3 and your answer is x=2.
Answer:
since X would be equal to 9, x + 2 would be equal to 11
Answer:
Amount of Discount: 85, Discounted cost of item: 340
Step-by-step explanation:
You Start by dividing the main price of the item by 100
You then multiply your answer from that by however much the discount is.
We divide by 100 because there is 100 percent when you are paying full price, dividing by 100 gives you the amount that is equal to 1 percent of that price
You then multiply the answer from that by 20, this will give you 20% of the full price, this will give you a discount of 85 Dollars.
To find the Discounted price you then subtract 85 from 425 and you will have an answer of 340 dollars. Hope this helps!
