This would just be 7 1/5 + 3/5 since the negative sign gets distributed and makes (-3/5) into a positive number.
From there you have basic math and you get 7 4/5.
Answer:
Step-by-step explanation:
The first answer is that the sale price is 25% cheaper its a dumb question.
The second answer is the 2nd option because it states that sale prices are 30% of the original. For example if you had a $100 item it would cost you 30% of that original price. But if you went to the first store it would cost you $70 dollars because its 30% off of the original price.
Answer:
82.96 people/km^2
Step-by-step explanation:
people / square km
3.70 x 10^9
----------------- =
4.46 x 10^7
3.70 x 10^2
----------------
4.46
0.8295... x 100 = 82.959641 or rounded 82.96
There is the equal values method, so you can do:
x-4 = 4x-10 (remove x from both sides)
-4 = 3x -10 (add ten to both sides)
6 = 3x (devide by 3x)
2 = x
Check: (by plugging it into the equation)
y = 2-4 and y = 8-10
y = -2 and y = -2
that's matches so it is correct...
YOUR ANSWER IS:
(2, -2)
I hoped I helped sort things out, and have a great day!
