Move all terms that don't contain x to the right side and solve.

x = -1

Subtract 60 on both sides to get -40.

You are left with 40x=-40

Divide both sides by 40 to leave x by itself.

You get x=-1.

Answer with Step-by-step explanation:

The value of a digit due to its position in a number is called as place value.

For example, there's a number

23450

2 is in ten thousands place and it has a place value of 20,000

3 is in thousands place and it has a place value of 3000

4 is in hundreds place and it has a place value of 400

5 is in tens place and has a place value of 50

0 is in unit or ones place and has a value of 0

When we divide the number by 10, we move every digit from its current place value to the right.

23450 divided by 10 = 2345

Now,

2 is in thousands place and it has a place value of 2,000

3 is in hundreds place and it has a place value of 300

4 is in tens place and it has a place value of 40

5 is in unit or ones place and has a place value of 5

Answer:

42 minutes

Explanation:

The total amount of anything expressed in percentage is 100%.

The reason for this is that per cent means per hundred.

So, 100% is

100

, which is a whole.

Moving to the question, a total of 25% + 5% = 30% of the time is used up by commercials and credits.

The time left for the program is 100% - 30% = 70%.

This is 70% of 60 minutes or
