1/4 + 1/2 + x = −3/4 solve for x. (1/4 is one fourth, 1/2 is one half, -3/4 is negative three fourths)

1/4 + 1/2 + x = −3/4

get a common denominator 1/4

1/4 +2/4 +x = -3/4

combine like terms

3/4 +x =-3/4

subtract 3/4 from each side

x = -3/4 -3/4

x = -6/4

divide top and bottom by 2

x = -3/2

x = -1   1/2

Answer : x = -1  1/2

x = -7/4

Step-by-step explanation:

Identify the LCD (it is 4) and mult. all terms of the given equation by it:

1 + 2 + 4x = -3

Then:   4x = -3 -2 -1, or 4x = -7.  Therefore, x = -7/4.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
