What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Number of pages she write in a week = 9 pages
Number of weeks she writes = 7 weeks
So , to calculate the number of pages she write in 7 weeks =
Number of pages she write in a week × Number of weeks she writes
Number of pages she write in 7 weeks = 9 × 7
= 63 pages
Hence , the number of pages she write in 7 weeks is 63 pages

Ashley and her four friends went trick-or-treating. Each one of them got 4/5 of a bag of treats. How many bags of treats did they have in total?
Answer:
4 bags
Step-by-step explanation:
Since there were five in total, and each got 4/5 evenly, it's just basic adding while subtracting the amount from the other bags.
So to get 5/5, which is a full bag, you take portions out of the others to create a full one. Write out 4/5, five times, and then subtract the needed portions from a separate bag to combine a full one.
Mike reads 10 pages of a novel on night 1.
Each night after that, he reads three pages
more than the night before. At this rate,
Mike thinks he can finish reading his 219
page novel in 10 days. His brother says it
will take 22 days. Who is right? Explain.
Answer:
Thus at this rate, Mike would be able to finish reading the 219 novel in 10 days. Mike is right.
Step-by-step explanation:
Total number of pages of the novel = 219.
1st night, he reads 10 pages.
2nd night, he reads 13 pages.
3rd night, he reads 16 pages.
4th night he reads 19 pages.
5th night, he reads 22 pages.
6th night, he reads 25 pages.
7th night, he reads 28 pages.
8th night, he reads 31 pages.
9th night, he reads 34 pages.
10th night, he reads 37 pages.
Total number of pages read after 10 nights = 235
Thus at this rate, Mike would be able to finish reading the 219 novel in 10 days. Mike is right.

Question 1) In an auditorium, there are 22 seats in the first row and 28 seats in the second row. The number of seats in a row continues to increase by 6 with each additional row. A) Write an iterative rule to model the sequence formed by the number of seats in each row. Show your work. (B) Use the rule to determine which row has 100 seats. Show your work. ( No Plagiarism and only answer if you know how to work this problem out. Will Mark Brainliest).
Answer:
Please Mark as Brainliest!!!!!!
Step-by-step explanation
In an auditorium, there are 21 seats in the first row and 29 seats in the second row. The number of seats in a row continues to increase by 8 with each additional row. How would you find the 100th row?
We can take this as an arithmetic sequence, as the seats in next row is calculated by adding 8 to previous row
So here common difference will be 8
the first term is 21
the arithmetic sequence is given by:
Putting the values of a1 and d
for 100th row,
Putting n=100
3. The sequence 6, 18, 54, 162, … shows the number of pushups Kendall did each week, starting with her first week of exercising.
Give the rule you would use to find the 20th week.
Given sequence is:
6, 18, 54, 162, …
we can see that the common difference is not same so we will find the common ratio
The given sequence is a geometric sequence as are the same for consecutive terms
The geometric sequence is given by:
Hence,
2. Seats in 100th Row = 813
3. Rule is:
Keywords: Sequence, ratio
Answer:
see explanation
Step-by-step explanation:
The sequence is
22, 28, 34, ....
Since there is a common difference of 6 the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
a₁ is the first term and d the common difference
Here a₁ = 22 and d = 6, then
[tex]a_{n}[/tex] = 22 + 6(n - 1) = 22 + 6n - 6 = 6n + 16
Equate to 100 and solve for n
6n + 16 = 100 ( subtract 16 from both sides )
6n = 84 ( divide both sides by 6 )
n = 14
Thus the 14 th row has 100 seats

can someone help me to solve this queestion on Conditional Probability. In Evs and Life Science class, 25% of the students are boys and 75% of them are girls. The probability that boys passed in Statistics is 0.4 and the probability that girls passed in Statistics is 0.25. One student is selected at random. What is the probability that the selected student is passed in statistics?
Step-by-step explanation:
If a boy student was picked, the probability that they passed is 0.25 * 0.4 = 0.1.
If a girl student was picked, the probability that they passed is 0.75 * 0.25 = 0.1875.
Total probability = (0.1 + 0.1875) * 100% = 28.75%.

Answer:
Question 2: √x
Question 5: B and D
Step-by-step explanation:
If you move a factor from the denominator to the numberator (or vice versa) its exponent must flip sign.
I.e., [tex]\frac{1}{x^{-1}}[/tex] will become [tex]\frac{x^1}{1}}[/tex] which is x
Multiplying the same number x you must add the exponents. (1/3)+(1/3)+(1/3) is 1, so D is also x¹.
Therefore B and D are equivalent.

find the amount accumulated after investing a principal P for t years at an interest rate compounded k times per year .
Answer:
A = $2,122.20
Step-by-step explanation:
A = P(1 + r/k)^kt
Where,
A = future amount
P = principal = $1,500
r = interest rate = 7%
k = number of periods compounded = 4
t = years = 5 years
A = P(1 + r/k)^kt
= 1,500 (1 + 0.07/4)^4*5
= 1,500 (1 + 0.0175)^20
= 1,500 (1.0175)^20
= 1,500 (1.4148)
= 2,122.20
A = $2,122.20

Rewrite the logarithm log8(2) as an exponential expression then find the value of the logarithm
Answer:
exponential expression:
8ᵇ = 2
log8(2) = 0.333333333 or 1/3
Answer:
log8(2) = 1/3
Step-by-step explanation:
I don't know if they mean this by an exponential expression but:
set x = log8(2), then
8^x = 8^(log8(2))
By logarithmic properties:
8^x = 2.
notice that 8 = 2^3.
By exponential properties:
8^x = (2^3)^x = 2^(3x)
So 2^(3x) = 2 = 2^1.
Comparing exponents gives:
3x = 1 <=> x = 1/3.
So log8(2) = 1/3.
question below thanks
Answer:
x = 11
Step-by-step explanation:
Based on the two secants intersecting theorem, thus, we have:
(x + 5)*5 = (38 + 2)2
5x + 25 = (40)2
5x + 25 = 80
5x = 80 - 25 (subtraction property of equality)
5x = 55
Divide both sides by 5
x = 11
