hope this is correct
12 ounces = to .75 lbs
5/8lbs = 10 ounces
12 ounces
1- I didn't understand it
2).. (a/b)² (a/b)⁸
= (a/b)²+⁸ = (a/b)¹⁰
3) 3-⁵ = 1/3⁵ = 1/243
4) (x/y)"
d/dx (x/y) = (1/y)
d/dx (1/y) = 0
5) (2m⁴n³)⁵
= 2⁵ × (m⁴)⁵ × (n³)⁵
= 32 × m²⁰ × n¹⁵
= 32m²⁰n¹⁵
Since you know that DA and DC are equal in length, you can say 2x-3=x+2, when you add 3 to both sides, it becomes 2x=x+5, subtract x from both sides, and you find that x=5
