Answer:
Since, company A charge of $423.5 is less than company B charge of $450
Hence,
Company A should be hired to get the better deal.
Step-by-step explanation:
Dimension of room: 11 * 14 foot
Area of rectangle is given by length * width
Thus,
area of room using above formula = 11*14 square foot = 154 square foot
For company A
charge for 1 square foot = $2.75
Charge for room = charge for 1 square foot * area of room
= 2.75 * 154 = 423.5
Thus, Total money charged by company A as calculated above is $423.5
Given,
company B charges $450 per room
Since, company A charge of $423.5 is less than company B charge of $450
Hence,
Company A should be hired to get the better deal.
Actually, it is
pages left=total pages-pages read
pages read=(number of pages per hour) times (number of hours)
numbe rof pages per hour=40
x=number of hours
254=total pages
so
y=254-40x, not 4x
what is the question
if it is how many hours to read the book then
0=pages left
0=254-40x
add 40x to both sides
40x=254
divide by 40
x=6.35
6.35 days or aprox 7 days
equation is y=254-40x where y=pages left and x=number of hours read
Answer:
Is not a possible solution
Because the number of hours can not be negative
Step-by-step explanation:
Let
x------> the number of hours in the dog walking job
y-----> the number of hours in the sales job
we know that
-----> inequality A
------> inequality B
Remember that
If a ordered pair is a solution of the system of inequalities
then
the ordered pair must satisfy both inequalities
we have
------> Is not a possible solution
Because the number of hours can not be negative
Answer:
3/4 - 5/12 = 4/12 - 5/12 = -1/12
Step-by-step explanation:
Moby's addition and subtracting problem is as follows: Let us break the problem into solvable parts.
3/4 - 5/12
we will find the common factor of the denominator which are 4 and 12. The common factor is 12. We divide 12 by both denominator and multiply by the numerator .
3/4-5/12 = (9 - 5)/12 = 4/12 . This is his first error . 3/4 - 5/12 is equal to 4/12 not 3/12.
Now let us go to the second part which is the answer minus 5/12
4/12 - 5/12 = (4 - 5)/12 = -1/12
The final answer should be -1/12. This is another error that has been detected.
The correct answer combination should be as follows.
3/4 - 5/12 = 4/12 - 5/12 = -1/12

3) complementary: 12 and 78
supplementary: 102 and 78
