Hope this helps you
You'll calculate the amount it was decreased by :
15% is also 15/100
15/100 * 42000
The two 0's in 100 cut 2 of the 0's in 42000 making it :
15/1 * 420
15* 420 = 6300
So, 6300 is the amount that the price is decreased by, but the question says the price of the PC (personal computer) after the decrease has happened not the price it decreased by :
So,
42000 - 6300 = 35700.
Answer: The answer is -19.
Step-by-step explanation: We are given to write the numerical coefficient of -9x.
The given expression is a monomial with unknown variable 'x'.
We know that a numerical coefficient of a monomial is a constant multiplied to the variable(s). For example, in the term -5xy, the unknown variables are 'x' and 'y' and the numerical coefficient is -5.
Therefore, in -9x, the unknown variable is 'x' and the numerical coefficient is -9.
Thus, the answer is -9.
Inequalities are used to relate unequal expressions
The greatest whole number of square yards the teacher can buy is 4
The inequality is given as:

When the <em>number of square yards </em>of the white fabrics is 10.
It means that: x = 10
So, we have:


Collect like terms


Divide both sides by 10

The above inequality means that:
The greatest whole number of square yards the teacher can buy is 4

Answer:

Step-by-step explanation:
Mod of any number represents the absolute value of the number.
Therefore,
= 2.25




Now we can arrange these numbers in ascending order.
-2.25 < -1.25 < 0.75 < 1.25 < 1.75 < 2.25
Therefore,
