Explain about the substitution method?The algebraic approach to solving simultaneous linear equations is known as substitution method.
The value of one variable through one equation is substituted in the second equation in this procedure, as the name implies.It is only useful if the change of variable explains the situation and, ideally, makes it possible to solve the problem once it has been simplified. First, considering a situation in which variables exist, a substitution is simply a change of variable.Let the total amount Noah have be'y'.
The initial amount shared by Noah among 10 people be 'x'.
Then,
y = 10x
But,
Amount shared is decreased by 20, ans sharing with 5 people.
Then,
y - 20 = 5x
Put value of y.
10x = 5x + 20
On solving;
x = 20/5
x = 4
Thus, money is Noah wants to share with people if each person still gets the same amount is 4.

I have 1,792 Pokémon cards, I also have 7 friends. I want to split the cards between me and the 7 of them. How many cards should each person get? Does the answer of this question has a remainder? Solve and Explain how you got your answer
We can confirm that each person should receive exactly 224 Pokémon cards, and there won't be any cards left over.
To split the 1,792 Pokémon cards equally between 8 people, including yourself and your 7 friends, you need to divide the total number of cards by the number of people:
1,792 cards ÷ 8 people = 224 cards per person.
So each person should get 224 Pokémon cards.
However, we should also check if there is a remainder after the division. To do that, we can multiply the number of cards each person is getting by the number of people and subtract it from the total number of cards:
224 cards/person x 8 people = 1,792 cards
1,792 cards - 1,792 cards = 0 remainder
Since there is no remainder, we can confirm that each person should receive exactly 224 Pokémon cards, and there won't be any cards left over.

Explain about the simple interest?A straightforward but effective idea. Very simply: interest is the benefit for saving - and the penalty of borrowing.
When you deposit funds into a savings account, you are paid interest, or additional money on top. The reason for this is that the bank gives you interest for letting them use your money.When someone owes money, they are assessed this fee.

The probability that the person selected is a tall, left-handed woman is 0.02.
Given that, The probability that the person selected is a woman is P(W) = 38% = 0.38
The probability that the person selected is tall is P(T) = 54% = 0.54
The probability that the person selected is left-handed is P(L) = 11% = 0.11
It is given that the events W, T, and L are independent of each other. Therefore, their joint probability is given by:
P(W ∩ T ∩ L) = P(W) × P(T) × P(L) = 0.38 × 0.54 × 0.11 = 0.02292
Now, the probability that the person selected is a tall, left-handed woman is given by:
P(T ∩ L ∩ W) = P(W ∩ T ∩ L) = 0.02292 = 0.02

Coins are placed into a treasure chest, and each coin has a radius of 1.4 inches and a height of 0.0625 inches. If there are 230 coins inside the treasure chest, how many cubic inches of the treasure chest is taken up by the coins? Round to the nearest hundredth and approximate using π = 3.14.
Answer: 32.2 cubic inches
Step-by-step explanation:
The volume of one coin can be calculated using the formula for the volume of a cylinder: V = πr^2h, where r is the radius and h is the height.
Substituting the given values, we get:
V = π(1.4)^2(0.0625)
V ≈ 0.14 cubic inches (rounded to the nearest hundredth)
To find the total volume of all the coins, we can multiply the volume of one coin by the number of coins:
Total volume = 230 × 0.14
Total volume ≈ 32.2 cubic inches (rounded to the nearest hundredth)
Therefore, the coins take up approximately 32.2 cubic inches of the treasure chest.

Olivia and Kalina are running a lemonade stand for one weekend. They sell lemonade for $0. 75
per cup. On Saturday, they sell 37 cups. For the weekend, they want to make at least $45. 00 in
sales on lemonade. Let c be the number of cups they sell Sunday,
If they sell 12 cups on Sunday will they reach their goal? Show this work on your paper and use it
to help you answer the next question. *
Yes, they will reach their goal of $45.00 by selling 12 cups of lemonade on Sunday.
Yes, they will reach their goal. To calculate this we can use the following formula:
Total Sales = (Number of cups sold on Saturday × Price per cup) + (Number of cups sold on Sunday × Price per cup)
Total Sales = (37 × 0.75) + (12 × 0.75)
Total Sales = 27.75 + 9
Total Sales = 36.75
Since 36.75 is greater than the goal of 45.00, they will reach their goal. This can be further verified by looking at the total cost of the cups they sold. 37 cups sold on Saturday at $0.75 each will cost $27.75. Adding the 12 cups sold on Sunday at $0.75 each will cost $9, bringing the total cost of the cups sold to $36.75. This is the same amount that was calculated using the formula above. Therefore, they will reach their goal by selling 12 cups of lemonade on Sunday.

The expression that is used to find the x-coordinate of that midpoint is expressed as: [(x)1 + (x)2]/2, which denotes the average of the x-coordinates. Similarly, the expression that is used to find the y-coordinate of that midpoint is expressed as: [(y)1 + (y)2]/2, which is the average of the y-coordinates.
We are given the coordinates of the endpoints of the line as;
K(-11, 2) and L(-19, 6)
Thus;
Midpoint Coordinate = (-11 - 19)/2, (2 + 6)/2
= (-15, 4)

Answer: x=10
Step-by-step explanation:
sum of all the angles inside triangle is equal to 180degrees.
First angle: 9x-16
Second angle: 7x-5
Third angle: 3x+11
let's sum this angles:
9x-16+7x-5+3x+11=19x-10=180
19x=180+10=190
x=190/19=10
