An empty shipping box weighs 250 grams. The box is then filled with T-shirts. Each T-shirt weighs 132.5 grams. The equation W=250 + 132.5T represents the relationship between the quantities in this situation, where W is the weight, in grams, of the filled box and T the number of shirts in the box.
The sub says that when the total weight of the box is 2,900 grams (W= 2,900) then the number of shirts in the box is 10 (t=10). Are they correct?
No.
10 shirts would mean the box weighs 1,575
2,900=250+132.5T
2,900=250+132.5(10)

Dr. Stickley says that the equations 2x-5=15 and 2(x-5)=15 are NOT equivalent equations. Is he correct?
He is correct. x=5 in the first equation whereas x=12.5 in the second equation. Since they don't have the same solution they are not equivalent equations.
