FInd the value of x.

x = 11

Step-by-step explanation:

< FEB = 180 - 4x                                   A straight line has 180 degrees.

The angle 147 is a remote exterior angle.

Therefore 180 - 4x + x = 147               Subtract 180 from both sides

-4x + x = 147 - 180

-3x = - 33                                              Divide by -3

x = - 33/-3

x = 11

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

i did it myself and i got 4.2 (b) hope its right
