Answer:
Step-by-step explanation:
We have been given that a kitchen floor has tiles in an area of square feet.
To find the number of tile in one square foot, we will divide total number of tiles by total area as:
Convert mixed fractions into improper fractions:
Now, we will convert the division problem to multiplication problem by flipping the 2nd fraction as:
Therefore, tiles are in one square foot.
We want to see if the given function represents a linear function.
We will see that yes, it does.
So we have the function:
y = f(x) = 30 + 5*x
And a general linear function is written as:
y = a*x + b
where a is the slope and b is the y-intercept.
Comparing these two, we can see that both have the same general shape, thus, our function is also a linear function.
A graph of our function also can be seen below, where it is evident that it is a line.

Answer:
cost of apples = 1.25 per pound
Step-by-step explanation:
from the question 10 pound box of apple costs 12.5.
ratio is a comparison of two variables and is usually done by division.
ratio of cost to number of pound will be
breaking down the denominator to 1, divide both numerator ad denominator by 10.
ratio of cost to number of pound will be
this can be written as 1.25 per pound or 1.25/pound
Hence the cost of apples per pound will be 1.25
Answer:
20.4 feet
Step-by-step explanation:
I think you mean the value of 'm' not 'b' as there is no 'b' variable given in the equation.
Assuming you meant 'm' then,
5 - 10m = 3m
+ 10m + 10m
5 = 13m
/13 /13
0.384615385 = m
