Answer: 1) 2 r+ 1.60 b = 10
2) r(b) = 5 - 0.8 b
3) b(r) = 1/0.8(5 - r)
Step-by-step explanation:
Here, b be the number of pounds of beans Lin buys and (r) be the number of pounds of rice she buys when spending all her money on the meal.
Brown rice costs $2 per pound, and beans cost $1.60 per pound. Lin has $10 to spend on these items.
Therefore, 2 r+ 1.60 b = 10
Which is the required expression.
Now for making b as independent, we can write the above expression,
2 r = 10 - 1.60 b
r(b) = 5 - 0.8 b
For making r as independent we can write the above expression,
1.60 b = 10 - 2 r
b(r) = 1/1.6(10 - 2 r)= 1/0.8(5 - r)

Answer:
B
Step-by-step explanation:
By looking at the problem, we can realize that all the three terms share the constant 3 and the variable u, so 3u is our GCF. Now, we factor out 3u, and divide each term by 3u to show what's left:
3u( 15u^3 / 3u + 9u^2v / 3u - 18uv^2 / 3u)
15u^3 / 3u --> 5u^2
9u^2v / 3u --> 3uv
- 18uv^2 / 3u --> -6v^2
3u(5u^2 + 3uv - 6v^2)
This aligns with option B, so B is the answer.
