Two angles lie along a straight line. If m∠A is five times the sum of m∠B plus 7.2°, what is m∠B?
soldier1979 [14.2K]

Answer:  28.8°

<u>Step-by-step explanation:</u>

∠A = 5(∠B) + 7.2°

∠B = ∠B

Since they are on a straight line, they form a linear pair (sum = 180°)

∠A + ∠B = 180°

Use Substitution:

5(∠B) + 7.2° + ∠B = 180°

Add like terms:

6(∠B) + 7.2° = 180°

Subtract 7.2° from both sides:

6(∠B) = 172.8°

Divide both sides by 6:

∠B = 28.8°

Solve the following inequality. Negative one-half p less-than negative 16 Which graph shows the correct solution?
Irina18 [472]

Answer:

p > 10.67

Step-by-step explanation:

Given the inequality -1 1/2p < -16

Before we can represent the inequality on a graph we just simplify it first. On simplification:

-1 1/2p < -16

(-3/2)p < -16

Multiplying both sides by 2

-3p < -32

Dividing both sides by -3 will change the sense of the inequality as shown:

p > -32/-3

p > 32/3

p > 10.67

Find the graph of the resulting inequality in the attachment.
