First, you would add 11x to both sides, because you are trying to separate the variable pieces and the constants (integers).
If performed correctly, you would get the equation
7x-5=6
Then, you would add 5 to both sides, to get the 7x alone.
This results in the equation 7x=11
Then, to get x alone, without a coefficient, you would need to divide both sides by 7.
x=11/7
You know that .5 = 0.5 = 5/10 = 1/2.
Mixed number sought: -9_1/2.
You would multiply 20 and 35% or 0.35 since there are 20 players on the team and 35% of them play the guard position. This would equal 7 and thus your answer would be 7 players.
X = 47°
y = 90°
These are the angles, comment if you would like to know the explanation but these are the answers
