In a class there are 40 students 30 are boys and what is the percentage of girls ....

Artyom0805 [142]

Answer:

25%

Step-by-step explanation:

Total= 40 students

boys +girls= 40

30 +girls= 40

number of girls

= 40 -30

= 10

Percentage of girls

$= \frac{10}{40} \times 100\% \\ = 25\%$

Alternatively,

percentage of girls

= 100% -(percentage of boys)

$= 100\% - ( \frac{30}{40} \times 100\%) \\ = 100\% - 75\% \\ = 25\%$

What values of x make the two expression below equal?

nasty-shy [4]

The denominator can't equal 0.
$11(x-7) \not= 0 \\ x-7 \not=0 \\ x \not= 7 \\ \\ \\ \frac{(2x+1)(x-7)}{11(x-7)}=\frac{2x+1}{11} \\ \\
(2x+1)(x-7) \cdot 11= 11(x-7) \cdot (2x+1) \\
11(2x+1)(x-7)=11(2x+1)(x-7) \\ \\
x \in R \setminus \{7 \}$

The answer is D.
