Find the value of x?

x = 35

Step-by-step explanation:

Since the sum of angle measures is 180, you can set up this equation:

40 + 3x + x = 180

Combine like terms:

4x + 40 = 180

Subtract 40 from each side:

4x = 140

Divide each side by 4:

x = 35

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
