Answer:
d² ≥ 17
Step-by-step explanation:
Answer:she bought 4 rolls of each color.
Step-by-step explanation:
Let x represent the number of rolls or spools of purple thread that Mrs. Bradley bought.
Let y represent the number of rolls or spools of orange thread that Mrs. Bradley bought.
Mrs. Bradley bought 8 spools of thread. This means that
x + y = 8
Each spool of purple thread is 3 meters long and each spool of orange thread is 4 meters long. If Mrs. Bradley bought 28 meters of thread in total, it means that
3x + 4y = 28
Substituting x = 8 - y into the equation, it becomes
3(8 - y) + 4y = 28
24 - 3y + 4y = 28
- 3y + 4y = 28 - 24
y = 4
Substituting y = 4 into x = 8 - y, it becomes
x = 8 - 4 = 4
The maximum pounds of celery she can buy is 3.25 pounds.
<h3>What are the linear equations that represent the question?</h3>
1.5c = o equation 1
1.50o + 1.80c = 8.10 equation 2
Where:
o = pounds of onions
c = pounds of celery
How many pounds of celery can she buy?
Substitute for o in equation 2 using equation 1
1.50(1.50) + 1.80c = 8.10
2.25 + 1.80c = 8.10
1.80 = 8.10 - 2.25
1.80c = 5.85
c = 5.85 / 1.80
c = 3.25 pounds
