Answer:

n = 12

Step-by-step explanation:

Given

(p^{20})(p^{-4})^2 = p^n

Required

What is n?

(p^{20})(p^{-4})^2 = p^n

Apply law of indices

(p^{20})(p^{-4 * 2}) = p^n

Express -4 * 2 as -8

(p^{20})(p^{-8}) = p^n

Apply law of indices

p^{20 - 8} = p^n

p^{12} = p^n

Cancel p on both sides

12 = n

n = 12

D, Because 7/15 + 9/15 is 16/15 + 4/15 =20/15 which equals 1 5/15 which turns into 1 1/3
A, 1/21 + 2/21 = 3/21 and that equals 1/7

C, 3/14+3/12 turns into 3/14+5/14= 10/14 - 8/14= 2/14=1/7

Answer:

25 girls

Step-by-step explanation:

Let

x denote number of boys

and

y denote number of girls

According to the statement that total 45 people came,

x+y = 45      => Eqn 1

And total paid amount was 175

So,

5x + 3y = 175    => Eqn 2

For solving, We will use the substitution method

So, from eqn 1

x = 45-y

Putting value of x in eqn 2

5(45-y) +3y = 175

225 - 5y + 3y = 175

-2y+225 = 175

-2y = 175-225

-2y = -50

2y = 50

y = 25

Putting y =25 in eqn 1

x+25 = 45

x = 45 - 25

x = 20

As y= 25

So, 25 girls came to the dance ..
