Joe knows a 5-pound turkey breast will feed 8 people. if 20 people are coming to joe's home for dinner, at this rate how many pounds of turkey breast will he need?

To find out how many pounds of turkey breast Joe will need for 20 people, he can set up a proportion and solve for x, the amount of turkey he needs.

pounds of turkey          5          x
# of people                  8     =  20

Use cross products to solve for x.

8x = 5 x 20
8x = 100
8      8
x = 12.5 pounds

Joe will need 12.5 pounds of turkey.

x=115.81

Step-by-step explanation:

If 14x = 14−−√131413, what value of x makes this equation true?

x is called a variable because it contains a value, which we are about to find.

If 14x = 14−−√131413, what value of x makes this equation true?

let's take it one after the other

divide both sides by 14

14x/14=14√131413/14

x=√131413

x=115.81

look for the square root of 131413

which going to be 115.81

so x=115.81
