Answer:

Step-by-step explanation:

You set up the equation, 2x + x + 10=55 and then combine the 3x + 10=55. Minus 10 to both side and that gives you 3x = 45 and divide 3x to 45 and then x = 15 and plug x in 2x(Measure 2) and that equals 30

2> -2-c. how would I graph this?

REY [17]

Answer:

-4< c

Step-by-step explanation:

2> -2-c

Add 2 to each side

2+2> -2+2-c.

4 > -c

Divide each side by -1. Remember that dividing by -1 will flip the inequality.

4/-1 < -c/-1

-4< c
