Answer:
Mean wage is the average wage for a worker in a specified position or occupation, which may be skewed up or down if there are a few extreme examples in the sample.
Step-by-step explanation:
Get the x variable on one side and the numbers another side.
9/10(x + 2/3) = 4 1/2
Distribute the 9/10 across the x and 2/3.
(9/10)x + 18/30 = 4 1/2
Simplify 18/30 to make our life easier.
(9/10)x + 3/5 = 4 1/2
Subtract 3/5 from each side of the equation.
(9/10)x = 3 9/10
Divide both sides by 9/10.
x = 4 1/3
The school can charge $7.54 for each agenda book.
Step-by-step explanation:
Given,
Purchase price of 350 books = $1137.50
Profit they want to make = $1500
Total amount = 1137.50 + 1500 = $2637.50
Therefore;
The school must sell 350 books for $2637.50
Thus,
350 books = 2637.50 dollars
1 book =
1 book = $7.535
Rounding off to nearest cent
1 book = $7.54
The school can charge $7.54 for each agenda book.

Answer:
24.75 = 3*4.50 + x*4.50
x= 2.5 pounds of Granny Smith apples
Step-by-step explanation:
Gala apples = 3 lbs
Granny apples = x lbs
They cost 4.50 a pound
Total cost = 24.75
Total cost = gala apples * cost per pound + granny apples * cost per pound
Substitute in what we know
24.75 = 3*4.50 + x*4.50
24.75 = 13.50 + 4.5x
Subtract 13.50 from each side
24.75-13.50 = 13.50-13.50 + 4.5x
11.25 = 4.5x
Divide by 4.50 on each side
11.25/4.5 = 4.5x/4.5
2.5 =x
Answer:
the third one
Step-by-step explanation:
x^2 is always non-negative, so -3x^2 will always be non-positive. You can eliminate any tables with positive values for y.
