One number is 8 more than the other. When the larger is divided by the smaller, the quotient is 7/5

Wewaii [24]

Answer:

<h3> The numbers are 20 and 28</h3>

Step-by-step explanation:

x - the other number (the smaller one)

x+8 - 8 more than the other number (the larger number)

$\dfrac{x+8}x=\dfrac75\\\\(x+8)\cdot5=x\cdot7\\\\5x+40=7x\\^{\quad-40\qquad-40}\\{}\quad5x = 7x-40\\^{\quad-7x\quad-7x}\\-2x=-40\\^{\div(-2)\quad\div(-2)}\\{}\ \ x=20\\\\x+8=28$

Answer:

B 9

Step-by-step explanation:

Use the rule of exponents for a division. To divide two powers with the same base, write the same base and subtract the exponents.

$\dfrac{a^m}{a^n} = a^{m - n}$

Now do it with your numbers.

$\dfrac{3^4}{3^2} = 3^{4 - 2} = 3^2 = 3 \times 3 = 9$
