Explain why this statement is true: 7a +4 – 2a = 7a + (-20)+4

MAVERICK [17]

Answer:

This equation has one solution so given statement is true.

Step-by-step explanation:

7a +4 – 2a = 7a + (-20)+4

5a + 4 = 7a - 16

5a - 7a = -16 - 4

- 2a = - 20

a = 10

This equation has one solution so given statement is true.

Which statement is the correct interpretation of the inequality –5 > –6? (1 point)

lilavasa [31]

Answer: OPTION D.

Step-by-step explanation:

The symbol of the inequality ">" means "greater than". Then, -5 is greater than -6.

If a negative number -a is greater than other negative number -b , then the distance between -a and zero is shorter than the distance between -b and zero.

You can see in the number line attached that -5 is closer to 0 than -6. Therefore, -5 is located to the right of -6.
