Answer:
x - y = -9
Step-by-step explanation:
from the equation
3y - x = 3
and x is four times the value of y
i.e x = 4y
put x = 4y into the first equation
we have;
3y - 4Y = 3
-Y = 3
Divide both sides by -1
we have
y = -3
so put y = -3 in the 2nd equation
i.e x = 4y
x = 4 × -3
x = -12
therefore x = -12 and y = -3
so tho find x - y
we have
-12 - (-3)
= -9
therefore x - y = -9
Answer: 48
Step-by-step explanation: To find the range of the data set shown here, remember that the range is the difference between the greatest number in the data set and the least number in the data set.
<em>Greatest number</em> → 64
<em>Least number → </em>16
Now, we need to subtract 16 from 64.
64 - 16 = 48
Therefore, the range of the data set is 48.
Answer: 0.02x
Step-by-step explanation:
The value of the cars the salesman makes is x in this instance.
The salesman makes a 2% commission on every sale so this can be represented by multiplying 2% by the value of the cars which in this case is x.
= 2% * x
= 0.02 * x
= 0.02x
If for instance he sells $40,000 worth of cars, his commission would be:
= 0.02 * x
= 0.02 * 40,000
= $800
