Step-by-step explanation:
Answer: A, B, C
Step-by-step explanation:
To solve for the inequality, we would solve it as if it had an equals sign.
[subtract both sides by 12]
[multiply both sides by -4/9, remember to flip inequality]
Now, we know that the solution is less than or equal to 80/9, which is approximately 8.89.
Looking at the answer choices, A, B and C are the answers since they are both less than 8.89.
The solution to the inequality is all x that are less than or equal to 8.89. Therefore, from the given options A. 6, B. 7, and C. 8 are in the solution set.
To find the values in the solution set of the inequality -9/4x+12≥-8, we need to isolate x by subtracting 12 from both sides of the inequality giving us -9/4x≥-20. Then, we can solve for x by dividing both sides of the inequality by -9/4, remembering to reverse the inequality symbol because we are dividing by a negative number. This gives us x≤(20)(-4/9), which simplifies to x≤80/9. Now, we can check which values from the options A, B, C, D, and E are less than or equal to 80/9.
Therefore, the values in the solution set of the inequality are A, B, and C.

B. the variable y represents the pounds of roasted coffee in the 46$ purchase
C. the consumer spent 46$ and purchase 5 pounds of espresso
D. the consumer spent 46$ and purchase 5 pounds of roasted coffee
Answer: B. the variable y represents the pounds of roasted coffee in the 46$ purchase.
Step-by-step explanation:
Given: The rate of espresso = $8.50 per pound
The rate of coffee = $10.25 per pound
The equation represents a online purchase.
............(1)
and .................(2)
from equation (2), 8.5 is the coefficient of x, thus variable x represents the pounds of espresso and 10.25 is the coefficient of y, thus variable y represents the pounds of roasted coffee in the total purchase of $46.
And equation (1) represents the total pounds of espresso and roasted coffee.
Hence only option B is correct.
the answer is B because the x represents the amount of espresso purchased and y represents the amount of roasted coffee purchased.
in total 5 pounds were purchased and it cost a total of $46 for the combination of types of coffee
