When solving negative one over five (x − 25) = 7, what is the correct sequence of operations?

multiply each side by negative one over five , add 25 to each side

multiply each side by 5, subtract 25 from each side

multiply each side by negative one over five , subtract 25 from each side

multiply each side by −5, add 25 to each side

Multiply each side by −5, add 25 to each side

Step-by-step explanation:

Given expression:

According to the BODMAS (bracket, of, divide, multiply, add, subtract), to solve for x, we need to first multiply -5 on both sides, we get

Now, add 25 on both sides, we get

Hence, the correct sequence of operations is "Multiply each side by −5, add 25 to each side".

There are 25 marbles in the bag, and 8 of them are purple.
For the first draw, the probability of sticking your hand in the bag
and pulling out a purple marble is 8/25 .

You don't put the first one back in the bag, so now, there are
only 24 marbles in the bag, and 7 of them are purple.
For the 2nd draw, the probability of sticking your hand in the bag
and pulling out a purple marble is 7/24 .

The probability of BOTH things happening is

  (8/25) · (7/24)  =  (56/600)  =  9.33 %
