whats they answer to the equation n-4<-3(2+n)

n-4 < -3(2+n)

Remove parentheses:

n-4 < -6 - 3n

Add 3n to each side:

4n-4 < -6

Add 4 to each side:

4n < -2

Divide each side by 4 :

n < - 1/2 .

Any number less than -1/2 makes the original equation a true statement.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
