Answer:

w/2 = 7.5/5

3kg

Here's the detailed explanation:

Remaining question below:

Which proportion could Maddy utilize to solve this issue?

a. w/2 = 7.5/5

b. w/7.5 = 5/2

Solve the proportion to determine the weight of a 2 liter jug.

_____kg

A 5-liter container of sports drink weighs 7.5kg

A 2-liter jug of this drink will weigh x kg

Finding w

Ratio of weight to volume

7.5kg: 5liters translates to 7.5/5

wkg: 2 liters means w/2

Establishing equivalent ratios

7.5 / 5 = w / 2

Cross-multiplying gives

7.5*2=5*w

15=5w

Dividing both sides by 5 results in

w=3

w=3kg

Thus, the weight of the 2-liter sports drink jug is 3kg

48,948 * 5% = 2447.4

Response:

If there are "p" pounds of peanuts and "m" pounds of a mixture containing '20% peanuts and 80% almonds', then we can formulate the following equations:

p + m = 10 -----------(1) and

4m/5 = 4 ------------(2)

The solution yields 5 lb peanuts and 5 lb mixture.

Detailed explanation:

In the mixture that Delaney desires to create, there will be

lb

= 6 lb of peanuts

Thus, there will be (10 - 6) lb

= 4 lb of almonds

If Delaney has "p" pounds of peanuts and "m" pounds of the '20% peanuts and 80% almonds' mixture, then based on the problem statement,

p + m = 10 -----------(1) and

4m/5 = 4 ------------(2)

From equation (2), we derive

m = 5 --------------(3)

From (1) and (3), we find that

p = (10 - 5) = 5
