Write out the subtraction in the proper order. You subtract -3n-7 FROM n+4. Thus, you must write n+4 FIRST. Next, insert a subtraction sign (-), followed by (-3n-7). MUST include those parentheses!

Here's what you should get: n + 4 - (-3n-7). Now remove the parentheses, changing signs where necessary:

n+4+3n+7. combine like terms (that is, combine the "n" terms and then combine the two numerals 4 and 7.

Find the percent of change: 100 acres to 140 acres

nydimaria [60]

Answer: 40%

Step-by-step explanation: First determine whether the number increases or decreases. Since the number changes from 100 to 140 it's getting bigger, so it increases.

To find the percent increase, we use the following formula.

The amount of change is the difference between the two numbers which is 40 and we get this by subtracting 100 from 140. The original number will be the number that we started with which is 100.

140/100 simplifies to 0<em>.</em>4.

Finally, we want the percent increase so we write 0<em>.</em>4 as a percent by moving the decimal point 2 places to the right to get 40%.

Therefore, the percent increase is 40%.
