Hi. Check my answers? Thanks? Also, if I got any wrong, explain to me why because inequalities confuse me sometimes
1. Julia is allowed to watch no more then 5 hours of tv a week. She has already watched 1.5 hours. Write and solve an inequality to show how many hours of television Julia can still watch this week.
T<5
T - 1.5 < 5 - 1.5
T = 3.5
(I know the answer's correct, but is the way I wrote it correct?)
2. You are a member of your local movie theater’s club. Every time you see a movie at the theater, you earn 2 advantage points. When you earn 100 points, you get a free movie pass. Currently, you have 40 advantage points.
A. Write an equation to model the number of movies, m, you have to watch before you earn a free movie pass.
B. Solve the equation. Show your work.
40 + 2m = 100
40 + 2m - 40 = 100 - 40
2m = 60
2m ÷ 2 = 60 ÷ 2
m = 30 movies
(Same here, I know the answer's correct, but is the way I wrote it correct?)
3. Write an equation with a variable on both sides of the equal sign that has infinitely many solutions. Solve the equation and explain why it has an infinite number of solutions.
x = x
Whatever value is on the right must match the one on the left. The equation is true regardless of the value of x.
(This one I'm not so sure it's correct)
