The average of anything is calculated by adding up all the terms in the data set and dividing by the amount of terms in the data set.
In this problem,
The average = $1000
the amount of terms = 3
x = the amount earned Sunday
($1073 + $1108 + x) / 3 = $1000
First, multiply both sides by 3
$1073 + $1108 + x = $3000
Add together like terms
$2181 + x = $3000
Subtract $2181 from both sides.
x = $819
The restaurant needs to earn $819 on Sunday to have an average of $1000
Is it 729 lol why would you put it as mixed number
Answer: slope, m = -1/2(coefficient of x in the equation
Step-by-step explanation:
y=-1/2x+4
We will compare the equation with the slope intercept equation ,
y = mx + c
Where y is the dependent variable
m is the slope
x is the independent variable
c is the intercept. This is where the line on the graph cuts the y axis
For y=-1/2x+4,
the intercept ,c is 4
Slope = m =-1/2
-1/2 is a negative slope because negative sign. This means the plotted line moves from up to down
Answer:
72y
Step-by-step explanation:
Multiplication can be done in any order
8x9=72
72 times y is 72y
Answer:
25
Step-by-step explanation:
A triangle is 180 degrees, we have the measures of 2 angles
ABC and BCA so we subtract 180-113-42=25
Hope this helps tell me if im correct
