Step-by-step explanation:
<u>Is this equation written correctly?:</u>
<u></u>
v(x)=12-2x-5.8
v(x) = -2x+6.2
v(-2) = -2(-2)+6.2
<u>v(-2) = 2.3</u>
v(0) = -2(0)+6.2
<u>v(0) = 6.2</u>
v(-5) = -2(-5)+6.2
v(-5) = 10+6.2
v(-5) = 16.2
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
49 pieces because 7/8 is equivalent to 49/56. If each piece is 1/56, then there 49 of them.
Step-by-step explanation:
x+x=66
2x=66
x=33
1st number is 33 and 2nd is 27
