Divide by the number of items.
o-na [289]3 years ago

Answer:

The number of items.

Step-by-step explanation:

1. add up all the prices of items.

2. divide by the number/amount of items.

This is how u figure out what the mean or in other words, average is.

Example:

There are three items, 1 apple, 1 orange, and 1 lemon. The cost of the apple is $1.50, the cost of the orange is $1.70, and the cost of the lemon is $1.90. We must add the cost of each other. The total of these 3 items is $3.40. Since we want to find the mean of these items we will have to divide by 3 since there are 3 items. This will give us a mean of $1.70.

Hope this helps ! :)

Solve for c.<br><br> 5c+16.5=13.5+10c
Kruka [31]

Answer:

c = 3/5

Step-by-step explanation:

5c+16.5=13.5+10c

Subtract 5c from each side

5c-5c+16.5=13.5+10c-5c

16.5 = 13.5 +5c

Subtract 13.5 from each side

16.5 -13.5 =13.5-13.5 +5c

3 = 5c

Divide by 5

3/5 = 5c/5

3/5 =c

Which statements are true about the ordered pair (−1, 5) and the system of equations?
Rudiy27
An ordered pair (x,y) is a solution to a system of equations if it makes all the equations true.
Let's check whether (–1, 5) makes the equations true.
Plugging –1 in the first equation for x and 5 in for y, we get
–1 + 5 = 4: TRUE
 Plugging –1 in the second equation for x and 5 in for y, we get
–1 – 5 = –6: TRUE

Since it makes both the equations true, it's a solution to the system of equations. So the answer choice is D, the 4th one.
