Answer:
20%
Step-by-step explanation:
Going of a guess, if you divide 20 by 100, then multiply .2 and 75 you get 15 and 75 - 15 is 60.
You need to know the slope and the y intercept
Okay -
So, the goal when we have an equation is to find the value of the variable. So, let's isolate that variable on <em>one </em>side of the equation!
<em>* original equation </em>
<em>5x + 4 = 49.
</em><em>* subtract four from both sides. if you do something on one side of the equation, you have to do it on the other.
</em><em>5x + 4 - 4 = 49 - 4.
* now we are going to divide 5 on both sides to isolate x.
5x/5 = 45/5.
* and our answer is...
x = 9. =)

That it tells you theres a chance you can lose,win or half/half.
15x + 11x + 8x+5 = 180
34x + 5 = 180
34x = 180-5
34x = 175
x = 5.147
by substitution each value by of x by 5
75 + 55 + 45 = 175
