Answer:
y = -2x + 8
Step-by-step explanation:
Answer: -4 or 4
Step-by-step explanation:
4*4 is 16
-4*-4 is 16
In order to find the original price, we need to divide by 4. This is because the price was reduced by 20%, it is 4/5 of the original price.
By dividing by 4, we can see that 90.40 is 22.60.
To find the original price, we add 22.60 (1/5 of the original price), to 90.40 (4/5 the original price) to find that $113 is the original price.
Answer:
30 liters
Step-by-step explanation:
To me it's kind of like multiplying and dividing.
So, what I did was 30,000 divided by 30 and got 1,000.
1,000 x 30 = 30,000.
That's what I did. You probably have your own way of doing it, but the answer is 30. I'm sorry if my explanation isn't good enough but I tried. Thanks for the question and enjoy your answer :)
Answer:
Step-by-step explanation:
x and y are proportional.
Let x = 45 and y = 5.
Solve for r (constant of proportionality).
Divide both sides by 45.
Simplify and switch sides.
