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
The estimation of 2.436 divided by 12 is approximately 0.203 .
The student wants to estimate the result of 2.436 divided by 12. The number 2.436 is closer to 2, therefore we can estimate it as 2. Now our division problem becomes 2.436 divided by 12. It would be less than 1 since 2 is smaller than 12. However, to get a more exact estimation, we could think of it as if every 1 of the 12 gets 1/6 of the 2, which means each one would get about 0.203. Therefore, 2 divided by 12 is approximately 0.203.

B. (a - b)(a + b)
C. a^2(b-b^2)
D. a^2b^2(b - a)
The factor of the expression into an equivalent form a²b - (ab)² would be; C
Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.
We need to factor the expression into an equivalent form a²b - (ab)²
This expression could also be given by;
a²b - (ab)²
Now, we know that:
a²- b² = (a + b) (a - b)
Now plug the values then we get;
Hence, the factor of the expression into an equivalent form a²b - (ab)² would be; C
