Beverages inc. sells espresso for 8.50 per pound and roasted coffee for 10.25 per pound. the following equations represent a recent online purchase. x+y=5 and 8.5x+ 10.25y=46. which of the following is true?
a. the variable x represents represents the pounds of roasted coffee in the 46$ purchase.
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

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.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
