So, problem statement tells you that 1lb = 16oz and that 1oz = 28.3g. That means that 1lb = 16 * 28.3g = 452.8g
You have three items, convert their weights to grams:1) 800g2) 1.6lb = 1.6 * 452.8g = 724.48g3) 30oz = 30 * 28.3g = 849g
So, sorting from greatest:3, 2, 1, or: 30oz, 1.6lb, 800g.
Answer:
49 x^4 - 4 = 0
(7 x^2 - 2) (7 x^2 + 2) = 0
Only the first term will have real roots
7 x^2 = 2
x = (2 / 7)^1/2 = .535 or -.535
Bill = 4b + 2.
Ron = 8b - 5.
Bill + Ron = (4b + 2) + (8b - 5).
= 4b + 8b + 2 - 5.
= 12b - 3.
That's the expression for the total number of blocks used by both Bill and Ron.
