Answer: To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself. The inverse operations are: Addition and subtraction.

When a number is added to 1/5 of itself, the result is 24. The equation that models this problem is n +1/5 n = 24. What is the v
Lady_Fox [76]

For this case we must find the value of n of the following equation:

n + \frac {1} {5} n = 24

Taking common factor "n" from the left side of the equation we have:

n (1+ \frac {1} {5}) = 24\\n \frac {6} {5} = 24

Multiplying by 5 on both sides of the equation:

6n = 120

Dividing between 6 on both sides of the equation:

n = 20

Thus, the value of n is 20.

Answer:

n = 20

How to put 634 in scientific form​
svetoff [14.1K]

Answer:

6.34 × 10²

Step-by-step explanation:

Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 634

New Number: 6.34

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 6 . 3 4

Decimal Count: 1 2

There are 2 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 6.34

b = 2

Now the whole thing:

6.34 x 10²

Step 4

Check your work:

10² = 100 x 6.34 = 634
