Solve for x.
7x – 9 < 12 or 1x + 8 > 11

1. x<3

2.x>3

Step-by-step explanation:

Number 1.

Step 1: Add 9 to both sides.

7x−9+9<12+9

7x<21

Step 2: Divide both sides by 7.

7x

7

<

21

7

x<3

Number 2.

1x+8>11

Step 1: Simplify both sides of the inequality.

x+8>11

Step 2: Subtract 8 from both sides.

x+8−8>11−8

x>3

leave alike if this help please.

b

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
