Answer:
NO!
Step-by-step explanation:
They are not equivalent. We can check this. If you rewrite them as fractions 13/14 and 1/2, you can cross multiply and see if they are equal. Which they are not. Also, you could just guess.... think of 13:14 as 13 out of 14. And 1:2 as 1 out of 2. You can tell that 13/14 is much greater than 1/2.
Answer:
By a quick online search, i found two tape diagrams:
13) You: -
Friend: - -
So you have one block, and your friend has two.
We know that you work for 3 hours, this means that your only block must represent 3 hours.
And all the blocks represent the same amount of time, then each one of the two blocks of your friend also represents 3 hours.
Then in total, he tutored for 3 hours + 3 hours = 6 hours.
14) You: -
Friend: - - - - -
In this case, you still have only one block, but now your friend has 5.
Using the same reasoning as above, we can conclude that each block represents 3 hours, and your friend has 5 of them, this means that he tutored for:
5*3 hours = 15 hours
There is nothing there to work with
Answer:I believe the answer is D
Step-by-step explanation:
Answer:
12-3+(2.7x2)-7
Step-by-step explanation:
you would have to divide each number in the equation by 3 which would look like this:
36 / 3 = 12
-9 / 3 = -3
8 / 3 = 2.6666 repeating, which would be rounded up to 2.7
6 / 3 = 2
-21 / 3 = -7
i hope this helps :)
