3/(x+2) = 2/x
multiply both fractions by x(x+2) to cancel out the bottoms
so it becomes 3x = 2x+4
ow subtract 2X from both sides and you get
x = 4
so it took Juan 4 hours
it took Yumi 2 hours more so 4+2 = 6 hours
B because the amount of toys you have and calories you eat do not depend on one another
Answer:
I think it would be the bottom left angle, x + 20 = 20x.
Why the others are smaller:
10x (x + 10)
12x (2x + 10)
10x (x + 10)
Step-by-step explanation:
The correct answer is ∠Y = 75°
because
45°∠A ∼ ∠X
∠B ∼ ∠Y = 75°
60°∠C ∼ ∠Z
45 + 60 = 105
180 -105 = 75
