Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister. Miguel is 65 years old. Using the results from Part C, write an equation to find Paula’s age, p (in years).
Previous equation answer:
Yes the values are the same
3r = 45
3(15) = 45
Answers
Answer:
3(15)+60p+65=45
Step-by-step explanation:
Paula’s age, p is 5/6 years.
Given that, Raul’s grandfather is Miguel age=65 years.
How do solve age problems?Important Statements and Equations for "Problems based on Ages":
If the present age is y, then n times the present age = ny.If the present age is x, then age n years later/hence = x + n.If the present age is x, then age n years ago = x – n.The ages in a ratio a: b will be ax and bx.If the current age is y, then 1/n of the age is y/n.Let Raul’s sister Paula's age be p and Raul’s age be r.
From the statement, Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister.
We can write the equation as follows r=65-60p
In part C:
39=3r-6
⇒r=15
So using the part C answer we get 15=65-60p
⇒60p=65-15
⇒p=5/6 years
Therefore, Paula’s age, p is 5/6 years.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

A pitcher contains 14.25 cups of iced tea. You drink 2.5 cups of the tea each morning and 2.25 cups of the tea each evening. When will you run out of iced tea?
Answers
Answer:
You will run out of iced tea in 3 days (a total of 3 mornings and 3 evenings)
Step-by-step explanation:
Day 1 - 9.5 cups left
14.25 - 2.5 - 2.25 = 9.5
Day 2 - 4.75 cups left
9.5 - 2.5 - 2.25 = 4.75
Day 3 - 0 cup left
4.75 - 2.5 - 2.25 = 0
Answer: You will run out of iced tea in 3 days
Step-by-step explanation:
2.5 + 2.25 = 4.75

Lorraine writes the equation shown. x squared + y minus 15 = 0 She wants to describe the equation using the term relation and the term function.
Answers
Answer:
x=2 y=11
Step-by-step explanation:
Answer:
The equation represents: A relation and a function
Step-by-step explanation:
A function is said to be a relation; however, the relation does not have to function. For a relation to result in a function, then every input gives an important output. Thus; the given information x² + y - 15 = 0 can be re-written as:
y = - x² + 15
Similarly, the equation typically illustrates a relation as well. Consequently, suppose we replace any x-value for x, then the one possible output will be for y. Hence, that is also a function.

A corner shelf is in the shape of a triangle. One side measures \(2x^2 + 2x -1\) while another side measures \(5x + x^2 - 3\)
What is the total of two sides? Show all work.
If the perimeter measures\(3x^3 - x^2 - 8x +1\) what is the length of the missing side? Show all work.
If we know that \(x =2\) then what are the lengths of the three sides of the triangle? Show all work.
Is it possible to have these side lengths? Why or why not?
Answers
1.The total of two sides is: $6 + 8 = 14$.
2.The missing side has a length of 4.
3.All three inequalities are true, so these side lengths do form a valid triangle.
4. It is not possible to have side lengths.
1. To find the total of two sides of the triangle shelf, we simply add the two given side measurements together.
2. $Perimeter = a + b + c$ where a, b, and c are the lengths of the three sides of the triangle. We are given that the perimeter measures 18, and we know that 6 and 8 are two of the sides, so we can substitute these values into the formula to solve for c:
$18 = 6 + 8 + c$
$18 - 14 = c$
$4 = c$
3. If we know that $a$ = 3, $b$ = 5, and $c$ = 8, we can check if these side lengths form a valid triangle by using the triangle inequality theorem, Therefore, we need to check if:
$a + b > c$
$b + c > a$
$a + c > b$
Substituting in the given values, we get:
$3 + 5 > 8$ (True)
$5 + 8 > 3$ (True)
$3 + 8 > 5$ (True)
4. of $a$ = 2, $b$ = 4, and $c$ = 7 for a triangle. The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side. If we apply this to the given values, we get:
$a + b > c$
$2 + 4 > 7$ (False)
For such more questions on inequalities
https://brainly.com/question/25275758
#SPJ8
The total of two sides is a + b.
If the perimeter is P, then we have a + b + c = P, where c is the missing side. Solving for c, we get c = P - a - b.
If we know that a + b = c, then we have a + b = a + b + c - b - a, which simplifies to 0 = c. This means that the triangle has one side of length 0, which is impossible.
Therefore, it is not possible to have these side lengths.
Without knowing the values of a and b, we cannot find the total of two sides, the length of the missing side, or the lengths of the three sides of the triangle.
