Answer:
A. 17
Step-by-step explanation:
Solve for q:
[tex] \longrightarrow[/tex] 5q - 10 = 75
Add 10 to both sides:
[tex] \longrightarrow[/tex] 5q + (10 - 10) = 10 + 75
10 - 10 = 0:
[tex] \longrightarrow[/tex] 5q = 75 + 10
75 + 10 = 85:
[tex] \longrightarrow[/tex] 5q = 85
Divide both sides of 5q = 85 by 5:
[tex] \longrightarrow[/tex] [tex] \sf \dfrac{5q}{5} = \dfrac{85}{5} [/tex]
[tex] \sf \dfrac{5}{5} [/tex] = 1:
[tex] \longrightarrow[/tex] q = [tex] \sf \dfrac{85}{5} [/tex]
[tex] \sf \dfrac{85}{5} [/tex] = 17:
[tex] \longrightarrow[/tex] q = 17
