Evaluate 4|-2| - |-3|

Nitella [24]

As we know these two lines mean | | a modulus sign. The modulus symbol is sometimes used in conjunction with inequalities. A modulus sign in simple words just ignores the sign and gives us the absolute value.

For example in this case the modulus gives us 4 x 2 - 3. As you can see the modulus sign has ignored the original negative signs with the numbers.

So after evaluating the equation the answer comes out to be 8 - 3 which is equal to 5.

Explain what needs to be fixed. 2n + 10 = -2 2n = 12 Step one n = 6 Step two

Brilliant_brown [7]

Answer:

step one needs to be fixed... you are supposed to subtract 10 from both sides of the equation.

Step-by-step explanation:

STEP 1: Move all terms not containing n to the right side of the equation.

$2n=-12$

STEP 2: Divide each term by 2 and simplify.

$n=-6$
