Question

8 - 1/4 n is greater than or equal to 20

Answer 1

Answer:

$n \leq -48$

Step-by-step explanation:

Step 1:  Convert to an expression

8 - 1/4 n is greater than or equal to 20

$8 - \frac{1}{4}n \geq 20$

Step 2:  Subtract 8 from both sides

$8 - 8 - \frac{1}{4}n \geq 20 - 8$

$- \frac{1}{4}n \geq 12$

Step 3:  Multiply both sides by -4

$- \frac{1}{4}n * -4 \geq 12 * -4$

Since we are multiplying by a negative we flip the greater than equal sign to a less than equal sign.

$n \leq -48$

Answer:  $n \leq -48$
