Josh made 8 3/4 cups of jello. if he serves it in 1/2 cup servings, how many people can he serve?

juin [17]

Answer: 17 people

Step-by-step explanation:

You divide 8 3/4 and 1/2 and you get 17 1/2

And since the question asks how many people can he serve you use the whole number because its not fair if you give a full serving to a person and half a serving to another.

Tema [17]

Answer:

solution,

Answer:

Answer ::+-6

Step-by-step explanation:

x:3=12:x

or, x/3 = 12/x

Doing cross multiplication,

x^2=36

Putting sqare root on both sides,

x= sqrt. 36

x= +- 6

Therefore x=+-6.

Answer:

$\Huge\boxed{x=15}$

Step-by-step explanation:

Hello There!

The angle labeled 6x is a right angle

If an angle is formed using the diameter of a circle then the opposite angle of that side is a right angle

So 6x = 90

isolate the variable

divide each side by 6

90/6= 15

6x/6=x

we're left with x = 15
