ss7ja [257]

Linear equation is the equation in which the highest power of the unknown variable is one.

The given equation the constant 2000 represents the base salary or the fixed salary of the salesman.

To find that what does 2000 represent in the given linear equation we need to know about the linear equation.

<h3>What is linear equation?</h3>

Linear equation is the equation in which the highest power of the unknown variable is one.

Given information-

Total sales by salesman each month is s dollars.

The total money made by the salesman each month by selling goods of s dollars given by,

S=2000+0.1s

The above equation given in the problem is the linear equation. In this linear equation the salary of salesman depends on his sales.

The constant amount of $2000 is the fixed amount of the salesman.

The variable s is the variable on which the salary of the salesman depends. Thus due to this variable the salary of the salesman changes.

Hence in the given equation the constant 2000 represents the base salary or the fixed salary of the salesman.

What is the qoutient of -18÷ (-1 over 6) ?
topjm [15]
...
When you divide a negative integer by a negative, it becomes a positive.  Also, when you have a problem like this...-18/-1/6, you switch the -1 and 6, leaving us -18/-6, but also, in the process of flipping the two numbers, we change to -18*-6.  Henceforth...-18/(-1/6)=-18*-6=108.

Alenkasestr [34]

Answer:

3.61 miles

Step-by-step explanation:

Given that:

Length of track = 5/6 of a mile

Number times Mary was able to run around the track = 4 1/3 times

Total miles ran by Mary :

(Equivalent mile of the track * number of times Mary ran around the track)

5/6 of a mile * 4 1/3 times

5/6 * 13/3

= 65 / 18

= 3.611111 miles

Hence, total Number of miles ran by Mary is 3.61 miles
