Answer:

x= 5.6

Step-by-step explanation:

we will need to put the information we currently have into an equation:

10•2•x= 112

then multiply 10•2 which equals 20...then the equation wil turn out like this:

20•x=112

now you will isolate the x... but how?? dividing 20 by itslef.. cancelling it out, and if you do one thing to the other side of the equation, you have to do it to the other...

20/20•x=112/20

you will end up with x= 122/20

you can use a calculator for this step, but to practice long division... (check the screen shot thingie)

hope this helped !! ^^

Assume there are 365 days in a year.

Dahasolnce [82]

The chance of student 1's birthday being individual is 365/365 or 100%.
Then the chance of student 2's birthday being different is 364/365.
Then it's narrowed down to 363/365 for student 3 and so on until you get all 10 students.
If you multiply all these values together, the probability would come out at around 0.88305182223 or 0.88.

To get all the same birthday you'd have to the chance of one birthday, 1/365 and multiply this by itself 10 times. This will produce a very tiny number. In standard form this would be 2.3827x10'-26 or in normal terms: 0.23827109210000000000000000, so very small.

Brad has two lengths of copper pipe to fit together. one has a length of 2 5/12 feet and the other has a length of 3 7/12 feet.

elena-s [515]

To find all of the feet of pipe that Brad has, you add both of the lengths of the pipes together. So 2 5/12+3 7/12. Add the numbers together first, 5. Then add the fractions, 5/12+7/12=1. So add 5 and 1 and you get 6 feet of pipe. Hope this helps.

Help don’t know what to do

nydimaria [60]

Answer:

Step-by-step explanation:

find the LCM of the two denominators 3 and 6 which is 6

equate in that such that 6÷3*2x=4x

6÷6×x=x

add the two=5x

5x/6=5

multiply by six both sides

5x=30

divide both sides by 5 to get x

x=6

hope it helps
