First, we divide the amount of tip which is $16 by the amount that is used to pay the food bill which is $80. Then, multiply the quotient by 100%. Mathematically,
($16 / $80) x 100% = 20%
Thus, you left 20% of the food bill for the tip.
7 ) 2. 000000

Its a
X(p-6) = z-8 => x = (z-8)/(p-6) if p≠6
Y=mx+b
7=6(3)+b
7-18=b
b=-11
y=6x-11 (i guess that is the answer)
Check the picture below.
so if x = 4, then 2x? surely you know that.
