Answer:
Step-by-step explanation:
<h3>Given</h3>
- P = 194
- l = 5w + 25
- l = ?, w = ?
<h3>Solution</h3>
<u>Perimeter formula</u>
<u>Substitute and solve for w:</u>
- 194 = 2(5w +25 + w)
- 194 = 12w + 50
- 12w = 144
- w = 144/12
- w = 12
<u>Find the length:</u>
Louisa needs 1.2 liters or 1200 milliliters of lemonade/punch for the picnic.
In a liter, there are 1000 milliliters
In 3 liters, there are 3000 milliliters
Therefore, we can set up an equation to represent how much milliliters Louisa needs.
Solve the equation and you should get 1200 milliliters.*
*If you need the number in liters, divide 1200 by 1000 and you should get 1.2 liters
You would need 24 machines
Because 1 machine makes 5 envelopes per minute so simultaneously 24 machines can make 120 envelopes per minute.
