Answer:

6 minutes

Step-by-step explanation:

Mr Crenshaw checks at a rate of 1/10 and Mr. Aguirre checks at a rate of 1/15.

If they work together, they will be checking at a combined rate of:

1/10 + 1/15 = [3(1) + 2(1)]/30

= 5/30 = 1/6

Their combined rate is 1/6 which means they check one set in 6 minutes

-1+(-3) is blank units from -1 in the blank direction
Thepotemich [5.8K]

-1+(-3) is  3 units from -1 in the left direction

-1+(-3) is blank units from -1 in the blank direction

-4 is  3 units from -1 in the left direction

because we know that

in the real line if we go 3 units in left from -1 we get -4

since in the real number line

the pattern is ................ - 5, -4, -3, -2, -1 ,0,1,2,3,4,5,............

thus we get  

-1+(-3) is blank units from -1 in the blank direction

-4 is  3 units from -1 in the left direction

What is the difference of the polynomials?
Vilka [71]

Answer:

8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6

Step-by-step explanation:

We want to simplify;


(8r^6s^3-9r^5s^4+3r^4s^5)-(2r^4s^5-5r^3s^6-4r^5s^4)


We expand the bracket to obtain;


8r^6s^3-9r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6+4r^5s^4


We now group the like terms to obtain;


8r^6s^3-9r^5s^4+4r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6


We now simplify to get;

8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6


The correct answer is C
