A recipe that yields 12 cups of soup calls for 28ounces of beef broth. How many ounces of beef broth do you need to make 18 cups

babymother [125]

We will ratio to solve this problem.
Given the first information, we know that for 12 cups of soup, there are 28 oz of beef broth. This can be expressed as 28/12.

With the second information, we know that for 18 cups of soup, there is x amount of beef broth. This can be expressed as x/18
In this case, x stands for broth.

Because these are ratios, we know they will equal each other. We can set up this as an equation.
28/12=x/18
Solve for x
28/12=x/18
28/12 can be simplified to 7/4
7/4 • 18= x
126/4 = x
31.5= x
ANSWER:
31.5 oz of beef broth is needed to make 18 cups of soup

Evaluate the expression 2x -x2for x =5

Bond [772]

Answer:

Step-by-step explanation:

First, you need to plug in the values for x. Here, we know that x = 5. So, when we plug it in we get 2^5 - 5^2. When we simplify, we then get 32 - 25. Thus, 32 - 25 = 7.

How to find the measure of an exterior angle on a triangle

nexus9112 [7]

Hi there!

There are many ways to find the measure of an exterior angle of a triangle. I'll explain the easiest method to you. As you can see in the image, a line is drawn extending a side of the triangle. In order to find the measure of the exterior angle, we can subtract the measure of the adjacent interior angle from 180 (a straight angle). Doing this subtraction will give us the measure of the exterior angle.

Hope this helps!! :)
