(-19)+9=-10, so there is 10 less people on the bus
You would want to divide the 86 feet by the 8 artist so you would do..
86 feet / 8 artists = 10.75 feet per artist
For the second part 10.75 would fall between 10 and 11
Adding the equations to eliminate p would be the correct step because when you add the equations together, the variable p would cancel out and be eliminated leaving you with 2w=35 you can then solve for the value of w which you can then input to find the value of p, allowing you to solve for the values of both p and w.
x = the unknown number

nine <u>times</u>(multiplication) a number(x) divided(division) by 2 equals(=) 54,
so 9x is divided by 2
N is the number of the Tshirt
c is the cost
the relationship between the cost and the number of the Tshirt is:
12n+3=c
so if 1 is the number of the tshirt so the cost is
12.1+3=12+3=15
if n=2 c=12.2+3=24+3=27
and etc.....
