I think that's the answer heh
Step-by-step explanation:
–3 [(8a−6a² + 9)+ (−10a−8+8a²)]
=−3−[8a−6a² + 9+ −10a− 8 + 8a²]
=−3−[(8a − 10a) + (−6a² + 8a² ) + (9 − 8)]
=−3−[−2a + 2a² +1]
=−3 + 2a − 2a² −1
= +2a − 2a² −4

if $10^{51} - 9$ is written as an integer in standard form, what is the sum of the integer's digits?
Notice the pattern:
10² = 100, so 10² - 9 = 91 with a digital sum of 9 + 1 = 10
10³ = 1000, so 10³ - 9 = 991 with a digital sum of 2•9 + 1 = 19
10⁴ = 10000, so 10⁴ - 9 = 9991 with a digital sum of 3•9 + 1 = 28
Then for an arbitrary power of 10, we have
[tex]10^n = 1\underbrace{00\ldots000}_{n\,\rm 0s} \implies 10^n - 1 = \underbrace{999\ldots99}_{n-1\,\rm9s}1 \\\\ \implies \text{digital sum} = 9(n-1)+1 = 9n - 8[/tex]
When [tex]n=51[/tex], the digital sum is 9•51 - 8 = 451.

A four-digit number is formed using four of the eight eight digits 1, 2, 3, 4, 5, 6, 7, 8. No digit can be used once. Find how many different four - digit number can be formed if
There are no restriction
Total 330 four-digit numbers can be formed if the number is odd and greater than 6000.
Let's tackle the problem in three steps.
First, take into account the numbers with "6" as the first digit on the left.
Then take the first eight digits of the numbers as the leftmost digit.
Last but not least, we'll use the numbers that begin with "7" as the leftmost digit.
1. As the leftmost digit, think of the numbers that begin with "6."
Any one of the final four odd digits—1, 3, 5, or 7—is acceptable (and recommended).
You are given four options.
You can use any of the remaining 8-1-1 = 6 digits for the second and third digit.
In all, it gives you 4×6×5 = 120 choices/numbers.
2. Consider the leftmost digit as the number starting with "6."
You have 120 more options/numbers using the same logic and analysis.
Everything is going well thus far, and you only need 120 + 120 = 240 numbers.
3. Consider the numbers starting with "7" as leftmost digit.
Any of the final three odd digits—1, 3, and 5—may (and ought to) be used.
You have three options.
Any of the remaining 8-1-1 = 6 digits can be used for the second and third digit.
In all, it gives you 3×6×5 = 90 choices/numbers.
4. You have 120 + 120 + 90 = 330 numbers/options when everything is added up.
Hence we get 330 choices to create four digit numbers.

Answer:
thank me that's is my answer
The number of players in the team will be 18.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Total cost to go to a tournament = $1885.50
Rent for bus = $949.50
Budget for meal for each player = $52
Now,
Let the number of players = x
So, We can formulate;
⇒ $949.50 + $52x = $1880.50
Solve for x, as;
⇒ $949.50 + $52x = $1880.50
Subtract 949.50 both side, we get;
⇒ $949.50 + $52x - $949.50 = $1880.50 - $949.50
⇒ $52x = $931
⇒ x = $17.90
After round we get;
⇒ x = $18
Thus, The number of players in the team will be 18.

tony charges 37.50$ for 1 1/2 hours of tutoring. how much would tony charge 7 1/2 hours of tutoring?
Tony have to get to pay $187.5.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
There are two cases in Unitary Method
Let's start with finding the price of one ice cream. Divide the entire cost of ice cream by the total number of ice creams to get at that. A single ice cream will cost you 125 divided by the amount of ice creams, or 25 cents. Consequently, 1 ice cream costs $25.
Step 2: To calculate the price of three ice creams, multiply the price of one ice cream by the quantity. Cost of 1 ice cream x number of ice creams = 25 x 3 = $75 is the price of 3 ice creams. The final cost is $75, which is the price of three ice creams.
Given:
For 1 1/2 or 3/2 hours tony charges = $37.50
For 1 hour tony charges = 37.50 * 2/3
= 12.5 * 2
= $25
Now, for 7 1/2 hours tony charges
= 15/2 * 25
= $187.5
Hence, tony charges $187.50 for tutoring 7 1/2 hours.

int decPrice = 15.75;
if (intQuantity >0 && intQuantity <10 || decPrice>20){

A bag contains 3 blue chips, 7 red chips, 4 yellow chips, and 5 green chips. A chip is randomly drawn from the bag. Find probability.
P( red or blue )
If a chip is randomly drawn from the bag, the probability it will be a red or a blue one is P(red or blue) = 10/19.
Probability of an event A is the number of event A divided by all possible outcomes. Mathematically,
P(A) = n(A)/n(S)
where:
n(A) = number of event A
n(S) = number of all possible outcomes or sample space.
Suppose A and B are independent outcomes, then:
P(A or B) = P(A) + P(B)
In the given problem:
Number of chips:
Blue = 3
Red = 7
Yellow = 4
Green = 5
Total chips = 3 + 7 + 4 + 5 = 19
If a chip is randomly drawn, the probability it will be a red one is:
P(red) = 7/19
Similarly,
P(blue) = 3/19

⇒ x ₋ 4 ₊ 2x ₋ 19 = 13
⇒ 3x ₋ 23 = 13
⇒ 3x = 13 ₊ 23
3x = 36
x = 36/3
x = 12
hence we get the value of x as 12.
now substitute x value to get ef and fg values.
ef = x ₋ 4 = 12 ₋ 4 = 8
fg = 2x ₋ 19 = 2(12) ₋ 19 = 24 ₋ 19 = 5
Hence we get the value of x as 12.
