I don't get 7/8n-3=5/8n+12??

Answers

Answer 1

Answer: 7/8n - 3 = 5/8n + 12
(7n)/8 - 3 = (5n)/8 + 12
7n - 24 = 5n + 96
7n = 5n + 96 + 24
7n = 5n + 120
7n - 5n = 120
2n = 120
n = 120/2
n = 60

The answer is: n = 60

Answer 2

Answer: Hey there, subtract 5/8n from both sides, 7/8n-3-5/8n+12-5/8n=1/4n-3=12, add 3 to both sides, 1/4n-3+3=12+3=1/4n=15, multiply both sides by 4, 4*1/4n=4*15, 4*15=60. So, n=60

length l = 14 inches

width w = 12 inches

and height h = 3.5 inches

apply volume formula that is = l × w × h .....................1

put here value we get

volume = l × w × h

volume = 14 × 12 × 3.5

volume = 588 in³

so maximum volume of box is 588 cubic inches

Answer:

588

The swimming pool that is 1.4 meters deep is deeper.

Hope this helps!

Why will the value of y for the function y = 5x + 1 always be greater than that for the function y = 4x + 2 when x>1?

Answers

Multiplication scales faster than addition. You're not just adding the last number, you're adding an additional count of the first number.

5 x 5 is a shortcut to writing 5 + 5 + 5 + 5 + 5

So, if x is 1:
5(1)+1 = 5 (times nothing really) + 1 = 6
4(1)+2 = 4 (times nothing again) + 2 = 6

If x is 2:
5(2)+1 = 5 + 5 + 1 = 11
4(2)+2 = 4 + 4 + 2 = 10
