Answer:

Step-by-step explanation:

p + c = 110

p = c + 100

c + 100 + c = 110

2c + 100 = 110

2c = 110 - 100

2c = 10

c = 10/2

c = 5 .......cost of the phone case

p = c + 100

p = 5 + 100

p = 105 <=== cost of the phone

The measure of an angle is three times the measure of its supplementary angle. What is the measure of each angle?

madreJ [45]

Answer:

45°

135°

Step-by-step explanation:

Let the measure of one angle be x

So, measure of its supplementary angle = 3x

$\implies \: x + 3x = 180 \degree \\ \\ \implies \: 4x = 180 \degree \\ \\\implies \: x = \frac{ 180 \degree}{4} \\ \\\implies \: x = 45 \degree \\ \\ \implies \: 3x = 135 \degree$

Solve the following inequality algebraically. ∣x−5∣≤11

Igoryamba

Answer:

$-6\leq x\leq 16$

Step-by-step explanation:

So we have the inequality:

$|x-5|\leq 11$

Definition of Absolute Value:

$x-5\leq 11\text{ or } x-5\geq -11$

Note that the sign is flipped in the second case because we multiplied by a negative.

Add 5 to both sides to both equations:

$x\leq 16\text{ or } x\geq -6$

Merge:

$-6\leq x\leq 16$

And we're done!
