A false equation is an incorrect equation; it says something erroneous or untrue. For example, 2 = 3 is a false equation, because 2 and 3 are different numerical values. To make a true equation, check your math to make sure that the values on each side of the equals sign are the same.

0 = 9(k - 2/3 (fraction) + 33 I need it with steps
daser333 [38]
0=(9k-6)+33  9*-2/3=-6/1
-33=(9k-6)  subtract 33 from both sides
-27=9k add 6 to both sides
-3=k divide both sides by 9

Factor 6y 2 - 48 + 42y
algol [13]
<h2>Answer:</h2>

The factorization of the given expression is given by:

           6y^2-48+42y=6(y-1)(y+8)

<h2>Step-by-step explanation:</h2>

To factor a polynomial means to express it as a product of the rational factor of the given expression.

The quadratic expression in terms of the variable y is given by:

6y^2-48+42y

It has three terms such that all the three terms are a multiple of 6 , hence we take out common 6 from each term to get the expression as:

6y^2-48+42y=6(y^2-8+7y)\\\\i.e.\\\\6y^2-48+42y=6(y^2+8y-y-8)\\\\i.e.\\\\6y^2-48+42y=6(y(y+8)-1(y+8))\\\\i.e.\\\\6y^2-48+42y=6(y-1)(y+8)

The number of students in a school fell from 700 last year to 646 this year. What is the percentage reduction?
leva [86]

Answer: 7.71%

Step-by-step explanation:

Number of students in a school last year = 700

Number of students in a school this year = 646

Reduction in the number of students = 700 - 646 = 54

The percentage reduction will be:

= Reduction in number / Last year students × 100

= (54 / 700) × 100

= 7.71%
