Explain how to add -7 + 12 as if you were teaching it to someone else.

1 answer:

3 0

Because 12 is bigger than 7, the answer will be positive because the bigger number is positive, and when you have a negative and positive you must subtract and use the sign of the bigger number.

Please help it’s a pic

Evgesh-ka [11]

Answer:

58°

Step-by-step explanation:

<MQR = <XQL (vertically opposite angles)

28 + 5b = 70 - 2b

28 - 70 = -2b - 5b

-42 = -7b

-42/-7 = b

6 = b

<MQR = 28 + 5b

= 28 + 5(6)

= 28 + 30

= 58°
