Answer:
5 and 25
Step-by-step explanation:
let the son's age be x then the father's age is x + 20
In 5 years
son = x + 5 and father = x + 20 + 5 = x + 25
Then
x + 25 = 3(x + 5) ← father is three times as old as son
x + 25 = 3x + 15 ( subtract x from both sides )
25 = 2x + 15 ( subtract 15 from both sides )
10 = 2x ( divide both sides by 2 )
5 = x and x + 20 = 5 + 20 = 25
si=on is 5 and father is 25
Answer:
The son is 5 and the father is 25.
Step-by-step explanation:
We can do this using Algebra.
Let the son be x years old.
Then the father's age is x + 20 years.
After 5 years the father's age is x + 25 and the son is x + 5 years.
So we can write the equation:
x + 25 = 3(x + 5)
x + 25 = 3x + 15
25 - 15 = 3x - x
10 = 2x
x = 5.
So the father's present age is 20 + 5 = 25 and the son is 5 years old.

need help on this I need all work shown as well, the subject is on similar triangles
Answers
Answer:
10 in
Step-by-step explanation:
If you draw a line parallel to the side of the cone through the center of the 10-inch (radius) circle, you create a right triangle with one leg 10 inches and a hypotenuse of 20+10 = 30 inches. It is similar to the right triangle shown on the diagram with leg 10 inches. That means the distance from the center of the 10-inch (radius) ball to the bottom of the cone is 30 inches.
Subtract from that the 10-inch radius and the 10-inch diameter of the two bottom balls shown, and you find the distance from the base of the smallest ball to the bottom of the cone is 30 -10 -10 = 10 inches.

Answer:$44.69
Step-by-step explanation:
Original cost = $45.87
Cost with sales = 45.87 x 0.10 since 10% is 0.10 as a decimal
New cost = (45.87) - (45.87 x 0.10)
=$41.283
Cost with tax = 41.283 x 1.0825 <- 8.25% is 0.0825 as a decimal
= $44.69
Answer:
$44.69
Explanation
10 Percent of $45.87 is 4.587 rounded to the nearest hundredth is $4.59.
$45.87 - $4.59 is $41.28
8.25% of $41.28 is 3.4056 rounded to the nearest hundredth is $3.41.
$41.28 + $3.41 is $44.69

Multi step equations that equal 17 with fractions
Answers
Answer:
7/1 - 7/1 + 17/1 = 17
Step-by-step explanation:
The solution to the equation (x/6 - 4 + 2/3) = -1/2, using the LCD or clearing method, is x =17 by solving multistep equations that equal 17 with fractions
To solve this equation, use the LCD (Least Common Denominator) method to eliminate the fractions.
The LCD in this case is 6, as it is the smallest number that both 6 and 3 (the denominators of the fractions) can evenly divide.
Step 1: Multiply every term in the equation by 6 to clear the fractions:
[tex]6 \times (x/6 - 4 + 2/3) = 6 \times(-1/2)[/tex]
Simplifying the equation:
[tex]x - 24 + 4 = -3[/tex]
Step 2: Combine like terms on the left side:
[tex]x - 20 = -3[/tex]
Step 3: Isolate the x variable by adding 20 to both sides of the equation:
[tex]x - 20 + 20 = -3 + 20[/tex]
Simplifying further:
x = 17
Therefore, the solution to the equation [tex](x/6 - 4 + 2/3) = -1/2[/tex] is [tex]x = 17[/tex].

Step-by-step explanation:
The outside factor multiplies each of the terms inside parentheses.
4(2x -4) = 4(2x) +4(-4) = 8x -16
_____
Additional comment
You can think of parentheses as a "bag". The factor outside tells you how many bags you have. When you dump that many bags (eliminate parentheses), you find that the number of each of the kinds of contents is the number in one bag, multiplied by the number of bags.
If you have 4 bags that each have 2 apples and 4 oranges, your total is 8 apples and 16 oranges.
) Kora is working on a scrapbooking project. She buys packages of stickers at two different stores.

Discount on Packages of Stickers
• Which expression represents the total price Kora
pays for 5 packages of stickers at Store A and
3 packages of stickers at Store B?
3{p - 100) + 512 -0.75) 5(p+1.00 +3(p+0.75)
Store A $1.00 off each package
Store B $0.75 off each package
5(p - 1.00) + 3(p -0.75)
3(p+1.00) + 5(p +0.75)
Answers
The expression that can be used to represent the total price is 3(p - $0.75) + 5(p - $1).
The expression that can be used to determine the total amount spent in store A is:
number of stickers bought x ( price of the item - discount) number of stickers bought = 5 price of the stickers = p discount = $15(p - $1)
The expression that can be used to determine the total amount spent in store B is:
number of stickers bought x ( price of the item - discount) number of stickers bought = 3 price of the stickers = p discount = $0.753(p - $0.75)
Total price = 3(p - $0.75) + 5(p - $1)

What is the term that describes how a cell must maintain a stable environment? (in: regulating temperature)
Answers
Answer:
homeostasis
Step-by-step explanation:
Homeostasis refers to the body's ability to maintain a stable internal environment (regulating hormones, body temp., water balance, etc.).
Answer:
Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside. All living organisms, from plants to puppies to people, must regulate their internal environment to process energy and ultimately survive.
The maintenance of stable, constant, internal conditions is called homeostasis. ... Like the walls of a house, cell membranes protect the inside of cells and maintain homeostasis through molecular transport. Controlling how much of which molecules enter or leave a cell allows cells to function properly.
