Zhi bought 18 tickets for games at a fair. each game requires 3 tickets. zhi wrote the expression 18 – 3g to find the number of tickets she has left after playing g games. diego correctly wrote another expression, 3(6 – g), that will also find the number of tickets zhi has left after playing g games. use the drop-down menus to explain what each part of zhi's and diego's expressions mean.

Equation 1

18 represents the number of tickets Zhi starts with. -3 is how many tickets each game uses, G is the amount of games played.

Equation 2

This equation is just equation 1 in factored form, 3 times 6= 18 and                   -g times 3= -3g. All of the parts are the same from the first equation.

Hope this helps some!!

Step-by-step explanation:

answer: the common difference is -0.10

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
