5.
120% is the same as 1.2 (from the percentage symbol go to places to the left and place a decimal). So we do:
5x + 5x(1.2)
Simplify to get:
5x + 6x = 11x
6.
7z - 1/3(7z)
Simplify the equation to get:
[tex]7z - \frac{7}{3} z[/tex]
Rewrite as:
[tex] \frac{21}{3}z - \frac{7}{3} z[/tex] and combine like terms to get [tex] \frac{14}{3} z[/tex]
8.
[tex] \frac{3}{4}v - 6( \frac{2}{9}y) [/tex]
Rewrite as:
[tex] \frac{3}{4} v - \frac{12}{9}y [/tex]
And simplify to get:
[tex] \frac{3}{4}v - \frac{4}{3}y [/tex]
10.
[tex]2x + \frac{2}{3}x + 5 + 11 - x [/tex]
Combine like terms:
[tex]x + \frac{2}{3}x + 16 [/tex] which becomes [tex] \frac{3}{3}x + \frac{2}{3} x + 16 [/tex]
Do it again and get your answer:
[tex] \frac{5}{3}x + 16 [/tex]
