Bob is diving
he is at a depth of 2 meters below sea level
sam goes down 4 times as deep
how deep is sam

depth is a negative thing because you are 2 below 0 or -2
then we mutiply -2 by 4 to get 4 times to get -8 meters below sea level

1/2 (4-k)=2/5 <br>Distribute and find LCM

borishaifa [10]

Answer:

20 -5k = 4
the LCM of the denominators is 10

Step-by-step explanation:

I find it convenient to do the problem in the reverse order: find the LCM, then distribute. That way, I'm not distributing a fraction.

The LCM of 2 and 5 is their product: 2·5 = 10. Multiplying the equation by 10 gives ...

5(4 -k) = 4

Now, distributing, we get ...

20 -5k = 4

The faces of a number cube are labeled 1 through 6. If the number cube is rolled 72 times, which is closest to the number of tim

Inessa [10]

18 times

Since there only two numbers greater than 4 (5 & 6), you subtract 2 from 6.

$6 - 2 = 4$

Then, you divide that from 72.

$72 \div 4 = 18$

So, the number of times I would expect the outcome to be greater than 4 is 18.
