Answer:
90 people
Step-by-step explanation:
Total: $775
DJ: $250
Cake: $75
Unknown party guests each getting $5
Let the unknown be x
We can form an equation; <em>DJ + Cake + x number of party guests = $775</em>
<em>250 + 75 + 5x = 775</em>
<em>325 + 5x = 775</em>
Subtract 325 from <u>both sides of the equals sign</u>.
<em>5x = 450</em>
Make <em>x</em> the subject and divide both sides by 5
<em>x = 90</em>
There were 90 party guests.

Answer:
Step-by-step explanation:
2x+(x)(3+x) multiple or foil the ()
2x+3x+x^2 combine like terms
5x+x^2 or x^2+5x
F(x)=-2if-1
f’(x)=d/dx (-2fi-1)
F’(x)=0
