First change to fractions   7 2/3 = 23/3      5 5/8 = 45/8

now you have 23/3 - 45/8     find least common denominator...24

23/3 = 184/24 -        45/8 =135/24 now your prob is 184/24 - 135/24

49/24   then change back 2 1/24

ANSWER

$x = 1.6$

EXPLANATION

The given equation is:

$- 0.5x - 2 = 2x - 1 - 6$

Group similar terms to obtain:

$- 0.5x - 2x = - 5 - 1 + 2$

Simplify similar terms,

$- 2.5x = - 4$

Divide both sides by -2.5

$x = \frac{ - 4}{ - 2.5}$

$x = 1.6$

Find the absolute value of the complex number 5 - 4i.

Damm [24]

I answered a similar question for someone else. The absolute value of a complex number is called the modulus. This represents the DISTANCE to the origin from the point on the imaginary + real plane.
the real horizontal distance is 5 and the imaginary vertical distance is in this case 4 (from -4i) the distance is 4. So to figure out this just use the Pythagorean theorem.
5^2 + (4)^2 = c^2
25 +16 = c^2
c^2 = 41c = 6.4 So option D.
