<h3> The complete exercise is: "Brown rice costs $2 per pound, and beans cost $1.60 per pound. Lin has $10 to spend on these items to make a large meal of beans and rice for a potluck dinner. Let b be the number of pounds of beans Lin buys and r be the number of pounds of rice she buys when she spends all her money on this meal.</h3><h3>1. Write an equation relating the two variables.</h3><h3>2. Rearrange the equation so "b" is the independent variable.</h3><h3>3. Rearrange the equation so "r" is the independent variable."</h3><h3 />
1. According to the information exercise given in the exercise, the cost per pounds of brown rice is $2. Since "r" represents the number of pounds of rice Lin buys, the total cost of the brown rice she buys can be represented with this expression:

The beans cost $1.60 per pound. Since "b" represents the number of pounds of beans Lin buys, the total cost of beans she buys can be represented as:

Knowing that she spends $10, you can write the following equation:

2. In order to rearrange the equation so "b" is the independent variable, you need to solve for "r":

3. To rearrange the equation so "r" is the independent variable, you must solve for "b". You get:

Answer:
its -1

They are the same amount. if you divide 60 by 5 it is 12 and when you multiply .75 by 12 it equals 9. so Both are $9.00 an hour.
45 + 7.80t ≤ 99.60
7.80t ≤ 54.60
t ≤ 7
They can rent a meeting room for no more than 7 hours.
<span>How does the volume of an oblique cylinder change if the radius is reduced to 2/9 of its original size & the height is quadrupled?
Volume of an oblique cylinder = </span>π * r² * h
radius is reduced to 2/9 of its original size = r * 2/9 = (2r/9)
height is quadrupled = h * 4 = 4h
Volume of an oblique cylinder = π * (2r/9)² * 4h
Assume: r = 9 ; h = 10
V = π * 9² * 10 = 3.14 * 81 * 10 = 2,543.40
V = π * (2²) * (10*4) = 3.14 * 4 * 40 = 502.4
The new volume decrease and is almost equivalent to 20% of the original volume.
