Answer: The number is 27
The system of equations is: 7x - 2y = 0
-9x + 9y = 45
<u>Step-by-step explanation:</u>
Let x represent the number in the tens place and y represent the number in the ones place. <u>x</u> <u>y</u>
Then 10x + y = 3(x + y)
When the digits are reversed: 10y + x = 10x + y + 45
Simplify each of the above equations and then create a system of equations:
10x + y = 3x + 3y → 7x - 2y = 0
10y + x = 10x + y + 45 → -9x + 9y = 45
9( 7x - 2y = 0) → 63x - 18y = 0
2(-9x + 9y = 45) → <u> -18x + 18y </u>=<u> 90</u>
45x = 90
x = 2
Input x = 2 into either equation to solve for y:
7x - 2y = 0
7(2) - 2y = 0
14 = 2y
7 = y
The answer to this question is x = 13/9 = 1.444
√42 is an irrational number, because you cannot express the answer as a fraction (ratio), and it certainly isn't a whole number or an integer.
The answer to the solution is x=43+√249/2
I hope this helps.
The answer is 6 pints equal to more than 60 fluid ounces
1 pint = 16 ounces.
6 pints = x
Use the proportion:
1 pint : 16 ounces = 6 pints : x
x = 16 ounces * 6 pints : 1 pint
x = 96 ounces
6 pints = 96 ounces > 60 ounces
Therefore, 6<span> pints equal to more than 60 fluid ounces</span>
