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.

Answer:

The solution set is (5,6).

Step-by-step explanation:

Given equations are:

-6x + 6y= 6 Eqn 1

-6x + 3y=-12 Eqn 2

Subtracting Eqn 2 from Eqn 1

(-6x+6y)-(-6x+3y)= 6-(-12)

-6x+6y+6x-3y=6+12

3y = 18

Dividing both sides by 3

$\frac{3y}{3}=\frac{18}{3}\\y=6$

Putting y=6 in Eqn 1

-6x+6(6)=6

-6x+36=6

-6x=6-36

-6x=-30

$\frac{-6x}{-6}=\frac{-30}{-6}\\x=5$

Hence,

The solution set is (5,6).

Answer:

$22,320

Step-by-step explanation:

1. Understanding

Mean is the average of a given set

2. Solving

We have to find the average of all of these numbers.

How do I find the average?

I add all of the numbers and divide by the number of numbers I added. Example:

(x + x + x + x)/4 or,

(x+x)/2 and examples in numbers:

(3+4)/2 or,

(9+4+8+5+7)/5

See what I mean? Dividing by the number of numbers I have.

Ok, now we know that, we can solve!

Here is the equation for this problem:

(24,600+19,000+33,000+15,000+20,000)/5 (We have 5 numbers)

We have to do Parentheses First

(24,600+19,000+33,000+15,000+20,000)/5 --> 111,600/5

111,600/5 = 22,320

22,320 is the average number of all of the numbers, which is the mean

Hope this helps :)

Evaluate the x. X/1 - 7 = 3

kherson [118]

Hey there!

Usually in equations, to clear the denominator, we multiply both sides by it. In our case here, the denominator is one, so when we multiply both sides by one we get the same thing. We can just remove the denominator:

c - 7 = 3

Using the property of equality which states that you do the same thing to both sides and get an equal equation, we can add seven to both sides in an effort to isolate x to get:

c = 10

To check, we plug in 10 for c:

10 - 7 = 3

3 = 3 (check!)

Hope this helps!
