Does a two-digit number exist such that the digits sum to 9 and when the digits are reversed the resulting number is 9 greater than the original number? Identify the system of equations that models the given scenario. t + u = 9 10t + u = 10u + t – 9 t + u = 9 10t + u = 10u + t t + u = 9 tu = ut + 9
The answer would be "t + u = 9 and 10t + u = 10u + t - 9". This can be found if you replaced t with 4 and u with 5. Adding the 2 digits would give you 9, and using the formula "10t + u = 10u + t - 9". Replace t and u with 4 and 5 then simplify. 10*4 + 5 = 10*5 + 4 - 9. Simplifying you'd get 45 = 54 - 9 or 45 = 45 which make the statement true. Thus making "t + u = 9 and 10t + u = 10u + t - 9" the answer.
I hope this helps!
The equations described in this problem are:
t + u = 9
10t + u = 10u + t - 9
When the two equations are substituted and solved, t = 4 and u = 5.
The original number described in the word problem is 45.

The length of the longer leg of a right triangle is 19ft more than five times the length of the shorter leg. the length of the hypotenuse is 20ft more than five times the length of the shorter leg. find the side lengths of the triangle.
This problem can be solved by creating and solving a quadratic equation based on the Pythagorean theorem. We denote the length of the shorter leg as 'x', and substitute '5x+19' and '5x+20' as lengths of the longer leg and hypotenuse in the theorem.
Explanation:The entire problem revolves around the application of the Pythagorean theorem, which in a right-angled triangle gives the relationship a² + b² = c², were a and b are the lengths of the shorter sides (legs) and c is the length of the longest side (hypotenuse).
Let's denote the length of the shorter leg as 'x'. From the problem, we know that the longer leg is 5x+19 and the hypotenuse is 5x+20. Using the Pythagorean theorem, we have:
((5x+19)² + x²) = (5x+20)².
You can solve this equation to find out the value of 'x', following which you can substitute this value back into 5x+19 and 5x+20 to find lengths of the longer leg and hypotenuse.

Mary had some cookies.she gave 2/9 of them to matthew and ate 1/3 of them. she had 8 cookies left. how many did she have at first?
Mary originally had 18 cookies. This is determined by creating and solving a ratio based on the fractions of cookies Mary had left after giving some away and eating some.
Explanation:The subject of this question is mathematics and it involves fractions. We can think of Mary's original number of cookies as 1 whole or 100%. We're told she gave away 2/9 of them and ate 1/3 of them, which means she hasn't touched 1 - 2/9 - 1/3 of the cookies.
First, we calculate the common denominator, which is 9. So, we must convert 1/3 to 3/9. Now, we have 1 whole - 2/9 - 3/9. This addition simplifies to: 9/9 - 2/9 - 3/9 = 4/9.
The 4/9 is equal to the 8 cookies she has left over. To find the original amount of cookies, we set up the following ratio: 4/9 = 8/x. Solve this ratio for x (which represents Mary's original number of cookies) by cross multiplying: 4x = 72. Divide both sides by 4 to get: x = 18 cookies.

The price has changed from $120 to $75. by how many percent did it change?
The price has changed by 37.5% from $120 to $75.
Explanation:To find the percentage change, we can use the formula:
Percentage change = ((new value - old value) / old value) * 100
In this case, the old value is $120 and the new value is $75. Plugging these values into the formula, we get:
Percentage change = (($75 - $120) / $120) * 100 = (-$45 / $120) * 100 = -0.375 * 100 = -37.5%
Therefore, the price has changed by 37.5%.

The percentage change in price from $120 to $75 is calculated by subtracting the initial price from the final price, dividing the result by the initial price, and then multiplying by 100. The price has decreased by 37.5%.
Explanation:The question involves calculating the percentage change in price. To do this, you start by subtracting the final price ($75) from the initial price ($120) to determine the difference. In this case, the difference is $120 - $75 = $45. This represents the total change in price.
To find out the percentage change represented by this difference, you divide the difference ($45) by the original price ($120) and then multiply the result by 100 to convert it to a percentage. This can be represented by the formula:
((Final Price - Initial Price) / Initial Price) x 100.
So, the percentage change would be calculated as follows: ((120 - 75) / 120) * 100 = 37.5%. Therefore, the price has decreased by 37.5%.
