Answer: x + 12 = 3x + -22
12 + x = 3x + -22
Reorder the terms:
12 + x = -22 + 3x
Solving
12 + x = -22 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
12 + x + -3x = -22 + 3x + -3x
Combine like terms: x + -3x = -2x
12 + -2x = -22 + 3x + -3x
Combine like terms: 3x + -3x = 0
12 + -2x = -22 + 0
12 + -2x = -22
Add '-12' to each side of the equation.
12 + -12 + -2x = -22 + -12
Combine like terms: 12 + -12 = 0
0 + -2x = -22 + -12
-2x = -22 + -12
Combine like terms: -22 + -12 = -34
-2x = -34
Divide each side by '-2'.
x = 17
Simplifying
x = 17
The hour all animals get fed at the same time if Frankie starts at 6:00 Am is 6:00 pm
<h3>Common multiple</h3><h3 />
- Hamster 4oz of food = 6 hours
- Guinea pigs 12oz of food = 12 hours
- Land tortoise 24oz of food = 24 hours
Find the lowest common multiple
- 6 hours = 6, 12, 18, 24
- 12 hours = 12, 34, 36
- 24 hours = 24, 48, 72
The lowest common multiple of 6, 12 and 24 is 12
if Frankie starts at 6:00 Am?
6:00 am + 12 hours
= 6:00 pm
Therefore, the hour all animals get fed at the same time if Frankie starts at 6:00 Am is 6:00 pm

Hi there,
58,000,000 in scientific notation is 5.8 x 10^7
this is because there are a least 7 zeros.
Hope this is correct :)

Answer:
x = 3
Step-by-step explanation:
To answer for x first distribute the 4 in the parenthesis
4x + 1 - 5x = 2x +4x - 20
Next add or subtract the x's
-x + 1 = 6x - 20
Now subtract 6x and 1 on both sides to get x on the left and the rest on the right
-7x = -21
Lastly, divide -7 on both sides
x = 3
Given:
Original price = $15.25
Tax rate = 7%
To find:
The total amount.
Solution:
We know that,
Total amount = Original price + Tax
According to the question,
Total amount = 15.25 + 7% of 15.25
Round to the nearest cent (two decimal places).
Therefore, the total value is $16.32.
