Question

Suppose that you want to mix two coffees in order to obtain 100 pounds of a blend. If x represents the number of pounds of coffee​ A, write an algebraic expression that represents the number of pounds of coffee B.
An algebraic expression that represents the number of pounds of coffee B is
nothing.​(Type an expression using x as the​ variable.)

Answer 1

Answer:

The required expression that represents the number of pound of coffees B is $100-x$

Step-by-step explanation:

Consider the provided information.

You want to mix two coffees in order to obtain 100 pounds of a blend.

Let x represents the number of pounds of coffee​ A and y represents the number of pounds of coffee​ B.

The obtained weight is 100 pounds.

$x+y=100$

$y=100-x$

Hence, the required expression that represents the number of pound of coffees B is $100-x$

Answer 2

The algebraic expression that represents the number of pounds of coffee B is 100 - x

Let x represents the number of pounds of coffee​ A and y represents the number of pounds of coffee​ B

Since 100 pounds of a blend is needed, hence:

x + y = 100

Making y the subject of the formula gives:

y = 100 - x

Hence the algebraic expression that represents the number of pounds of coffee B is 100 - x
