Which equation is false for x = 6?
A) 2x − 8 = 5
B) 3x + 7 = 25
C) 4x + 12 = 36
D) 6x − 6 = 30

choice A.  Since  12 -8 = 4  not 5

Step-by-step explanation:

if we plug in x =6 for  2x -8 = 5

2*6 - 8 =  12 - 8 = 4  not 5

Try B.   3*6 + 7 =   18 + 7 = 25 = 25   true

Try C.   4*6 + 12 = 24 + 12 = 36 = 36  true

Try D.   6*6 - 6 =  36 - 6 = 30  = 30  True

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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
