Answer:
21/40
Step-by-step explanation:
2 5/8 / 5 =
= 2 5/8 / 5/1
= 21/8 × 1/5
= 21/40
Since there are 5 cats and 2 dogs, divide cats by dogs for the number.
5/2= 2.5
There are 2.5 times more cats than dogs.
I hope this helps!

Hello!
log₃(x) + log₃(x - 6) = log₃(7) <=>
<=> log₃(x * (x - 6)) = log₃(7) <=>
<=> log₃(x² - 6x) = log₃(7) <=>
<=> x² - 6x = 7 <=>
<=> x² - 6x - 7 = 0 <=>
<=> x² + x - 7x - 7 = 0 <=>
<=> x * (x + 1) - 7 * (x + 1) = 0 <=>
<=> (x + 1) * (x - 7) = 0 <=>
<=> x + 1 = 0 and x - 7 = 0 <=>
<=> x = -1 and x = 7, x ∈ { 6; +∞ } <=>
<=> x = 7
Good luck! :)

Answer:
The diameter of the floor is 6 yards
Step-by-step explanation:
Here, we are to calculate the diameter of a circular floor that has a circumference of 18.84 yards
Mathematically,
C = π * D
where C is the circumference
Plugging the values of the circumference , we have ;
18.84 = 22/7 * D
7 * 18.84 = 22D
D = (7* 18.84)/22 = 5.99 which is approximately 6 yards
