4186.67 because you have to look at the hundredths place and thousands place. If the thousand place is 5 or more then the hundredth place goes up one. If it is 4 and less than it stays the same.
The answer is C. 1 because you after you subtract the numbers you get 5- -4 and that equals 1.
Answer:
For x=7 and y=9 Caleb and Eva will meet again. That is, Caleb will have made 7 labs and Eva 9 labs.
Step-by-step explanation:
In order to find the number of labs that Caleb and Eva must complete, to meet again at the start, you can use the following equation:
(1)
where x is the number of labs made by Caleb and y the number of labs made by Eva. The equation (1) means that for the specific values of x and y, Caleb and Eva will spend the same amount of minutes on the labs.
Then, you need to find the least integers values of x and y.
First, you solve the equation (1) for y:
(2)
By inspection you can find that the least value of x that makes possible that y is an integer, is 7
In fact, you have:
![y=\frac{18}{14}(7)=9](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B18%7D%7B14%7D%287%29%3D9)
Hence, for x=7 and y=9 Caleb and Eva will meet again. That is, Caleb will have made 7 labs and Eva 9 labs.
<u>Answer:</u>
$180
<u>Explanation:</u>
Alright, this took me a second of thinking.
So let's say our original price is x. Now to get to the discounted price of 135, we had to take off 25%. Because we know 25% of x is now gone, 135 must be 75% of x. So in this case we would divide 135 by .75 and that would give us 180.
Now to check this out, we just have to remove that 25% and see if we still get 135. So when we multiply 180 x .25 we get 45. Then subtracting our 45 from 180 we get 135, proving that the original price is indeed $180.
