Think i know but not sure hope someone can

add 20.35 + 14.65 = 35

35 + 20% = 42

each person ticket is 42

42 times 5 =210

210 is the cost of 5 people

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

x+10

(w – 2.5)(w + 2.5)
