Response:
Jack's weight on the moon will be 26.52 pounds
Step-by-step explanation:
x = 156 (Weight on Earth)
y = 0.17 (Moon's gravity)
z = Your weight on the moon
x * y = z
156 * 0.17 = 26.52
Jack will weigh 26.52 pounds.
Answer:
Kelvin miscalculated and wrote 60 incorrectly.
He should have calculated $30.65 minus 60% instead of using 0.60.
The accurate final equation is:
$30.65 - 60% = 12.26
The formula representing this scenario is 
The answer to this formula is 
Initially, you need to formulate the equation.

Next, simplify the expressions.

Afterwards, subtract 5.7 from both sides.

Lastly, divide both sides by 5

This question reveals an intriguing pattern.
The rule or pattern to follow here is:
For the left side of the number compared to its predecessor: (First digit x Third digit + 1)
For the right side: (Second digit x Fourth digit -1)
For instance, consider 6447. Next, let's examine its previous number, 9876.
Now,
and

that's how we arrived at 6447
Next, for the third number, 2527, let's look at its previous number, 6447
Now, 
and 
that's how we reached 2527
Following the same reasoning, the missing number should be 534.
This conclusion came from applying the rule of the pattern as:

and

Thus, we derived 534.
