Chapter 4: Problem 90

If a slice of cheese contains \(x\) calories and a glass of wine contains \(y\) calories, write an algebraic expression for the number of calories in 3 slices of cheese and 2 glasses of wine.

Short Answer

Expert verified
The algebraic expression for the total calories in 3 slices of cheese and 2 glasses of wine is \(3x + 2y\).

Step by step solution

01

Identify Variables

Given in the problem, there are two variables i.e., 'x', the calories in a slice of cheese and 'y', the calories in a glass of wine.
02

Write Expression for Cheese

Since it's given that 1 slice of cheese contains \(x\) calories, for 3 slices of cheese, the total calories will be \(3x\) because it's the product of the number of slices and the calories in one slice.
03

Write Expression for Wine

It's stated that 1 glass of wine contains \(y\) calories. Therefore, for 2 glasses of wine, the total calories will be \(2y\). This is because it's the product of the number of glasses and the calories in one glass.
04

Combine the Expressions

As we're supposed to find the total calories in '3 slices of cheese' and '2 glasses of wine', it will be the sum of the two expressions given above, i.e., \(3x + 2y\)

In Exercises \(45-56,\) solve each system by the method of your choice. If there is no solution or an infinite number of solutions, so state. Use set notation to express solution sets. Explain why you selected one method over the other two. $$\left\\{\begin{array}{l} 2 x-7 y=17 \\ 4 x-5 y=25 \end{array}\right.$$

Determine whether each statement 鈥渕akes sense鈥� or 鈥渄oes not make sense鈥� and explain your reasoning. Each equation in a system of linear equations has infinite many ordered-pair solutions.

The following system models the winning times, \(y,\) in seconds, in the Olympic 500 -meter speed skating event \(x\) years after 1970: $$\left\\{\begin{array}{l}y=-0.19 x+43.7 \\ y=-0.16 x+39.9\end{array}\right.$$ Use the slope of each model to explain why the system has a solution. What does this solution represent?

Will help you prepare for the material covered in the next section. Use both equations in the system $$\left\\{\begin{array}{l}3 x+2 y=48 \\\9 x-8 y=-24\end{array}\right.$$ to find \(x\) for \(y=12 .\) What do you observe?

In Exercises \(1-44,\) solve each system by the addition method. If there is no solution or an infinite number of solutions, so state. Use set notation to express solution sets. $$\left\\{\begin{array}{l} \frac{x}{3}+y=3 \\ \frac{x}{2}-\frac{y}{4}=1 \end{array}\right.$$
