Can someone please help me I keep getting negative numbers for number 12

1 answer:

5 0

Consider, pls, this option:
(the sum of three angles must be 180°)
(60+x)+(x+85)+55=180;
2x=-20;
x= -10.
Note, that 60+85+55=200 > 180!
60+x=50° and x+85=75°.
If to check the sum.: 75+50+55=180°

A classmate wrote the solution to the inequality |-4x + 1| > 3 as show below. Describe and correct the error.

Answer:

See below.

Step-by-step explanation:

The last step is incorrect. When we divide both sides by a negative the inequality is flipped. The answer is x < -1/2.

Also they omitted the other possibility that the expression in the vertical lines could be negative.

We also have the inequality

- 4x + 1 < - 3

-4x < -4

x > 1.
