The inequality that can be used to find m, the number of months after receiving his fish tank, when Dante will have less than 10 goldfish in his fish tank is 20 - 2m < 10

Since Dante has 20 goldfish and gives out 2 goldfish every month,

After one month, he has 20 - 2 = 20 - 1(2) gold fish left.

After 2 months, he has 20 - 2 - 2 = 20 - 4 = 20 - 2(2) goldfish left.

After 3 months, he has 20 - 2 - 2 - 2 = 20 - 6 = 20 - 3(2) goldfish left.

<h3>Number of goldfish after m months</h3>

So, after m months, he has 20 - 2m goldfish left.

<h3>The inequality to find m</h3>

For the number of goldfish to be less than 10, we have the inequality

20 - 2m < 10

So, the inequality that can be used to find m, the number of months after receiving his fish tank, when Dante will have less than 10 goldfish in his fish tank is 20 - 2m < 10

Although the actual amount varies by season and time of day, the average volume of water that flows over the falls each second

lutik1710 [3]

Given that the average volume of water that flows over the falls each second is $4.8 \times 10^5$ gallons.

There are 3,600 seconds in one hour.

Thus, in one hour, $4.8 \times 10^5\times3600=17280\times10^5=1.728\times10^9$ gallons of water flows over the falls.

Therefore, the amount of water that flows over the falls is $1.728\times10^9$ .

GIVING BRAINLIEST Try the numbers 4, 5, 6, 7 in the equation 6 ⋅ x + 5 = 12 + 5 ⋅ x

Harrizon [31]

<h3>6 is a solution to equation 6x + 5 = 12 + 5x</h3>

Solution:

Given equation is:

6x + 5 = 12 + 5x

Try the numbers 4, 5, 6, 7 in the equation to test whether any of them is a solution

Substitute x = 4

6(4) + 5 = 12 + 5(4)

24 +5 = 12 + 20

$29 \neq 32$

Thus 4 is not a solution

Substitute x = 5

6(5) + 5 = 12 + 5(5)

30 + 5 = 12 + 25

$35\neq 37$

Thus 5 is not a solution

Substitute x = 6

6(6) + 5 = 12 + 5(6)

36 + 5 = 12 + 30

$41\neq 42$

Thus 6 is not a solution

Substitute x = 7

6(7) + 5 = 12 + 5(7)

42 + 5 = 12 + 35

47 = 47

Thus 6 is a solution

Answer:

Graph A

Step-by-step explanation:

$y = {x}^{2} - 6x - 7 \\ plug \: y = 0 \\ {x}^{2} - 6x - 7 = 0 \\ {x}^{2} - 6x + 9 = 7 + 9 \\ (x - 3)^{2} = 16 \\ (x - 3) = \pm 4 \\ x = 4 + 3 \: or \: x = - 4 + 3 \\ x = 7 \: or \: x = - 1$
