-7 + 4n = 9
Show your work!
First of all, add 7 to both sides, in order to cancel the -7:
[tex] -7 + 4n +7= 9+7 [/tex]
As we said, the -7 on the left hand side cancels out, while we can add it to the 9 on the right hand side:
[tex] 4n = 16 [/tex]
Now, divide both sides by 4. As before, this is needed to cancel the four on the left hand side and isolate the x, while it is just a normal division between numbers on the right:
[tex] \dfrac{4n}{4} = \dfrac{16}{4} \iff x = 4 [/tex]
Rewrite the equation in an easier way: 4n-7=9
Add 7 to both sides: 4n-7+7=9+7... 4n=16
Divide both sides by 4: 4n/4=16/4

Type the correct answer in the box. Use numerals instead of words.
The high temperature in Rockport over the weekend was 55 1/4°F. Write this temperature value as a decimal number with two decimal places.
The decimal form of 55 1/4°F is °F.
Transform 1/4 into a decimal by dividing 1 by 4, which is 0.25. Then, add 55 to 0.25 to get 55.25. Hence, 55 1/4°F written as a decimal number is 55.25°F.
Explanation:To write the temperature value 55 1/4°F as a decimal number, we need to convert the fraction to a decimal. To do this, we divide the numerator (1) by the denominator (4), which gives us 0.25. Therefore, the decimal form of 55 1/4°F is 55.25°F.
To transform a fraction into a decimal, you divide the numerator (top part) by the denominator (bottom part). Here, 1⁄4 expressed in decimal form is 0.25. Therefore, to express 55 1⁄4°F as a decimal using numerals instead of words, you add 55 to 0.25. So, the temperature, filled in the box, would be 55.25°F.

What does 1/2 ( 3/5x - 8) + 7/4 ( 2/5x + 4)
To simplify the given expression, distribute the fractions and combine like terms. The final simplified expression is 1/x + 24.
Explanation:To simplify the given expression 1/2 (3/5x - 8) + 7/4 (2/5x + 4), we need to distribute the fractions across the terms. First, distribute 1/2 across 3/5x and -8, then distribute 7/4 across 2/5x and 4. This results in (3/10x - 4) + (14/20x + 28). Now, combine like terms by adding the coefficients of x. Thus, the simplified expression is (3/10x + 14/20x) + (-4 + 28).
To add the fractions (3/10x + 14/20x), we need to find a common denominator. The least common multiple of 10 and 20 is 20. Multiply the numerator and denominator of the first fraction by 2 and the numerator and denominator of the second fraction by 1 to obtain (6/20x + 14/20x). Now, add the fractions together to get (20/20x), which simplifies to 1/x.
Combine the constants (-4 + 28) to get 24. Therefore, the simplified expression is 1/x + 24.

Working together for the same time, 3 combine harvesters can harvest 480 acres, 4 combine harvesters can harvest 640 acres, and 12 combine harvesters can harvest 1920 acres.
If two combine harvesters can harvest 320 acres in a certain amount of time, we need to find out how many acres can be harvested by 3, 4, and 12 combine harvesters working together for the same amount of time.
1. **Three combine harvesters**:
Since 2 combine harvesters can harvest 320 acres, the harvesting capacity per harvester is:
- 320 acres / 2 harvesters = 160 acres per harvester in the given time.
Therefore, 3 combine harvesters can harvest:
- 3 harvesters * 160 acres per harvester = 480 acres.
2. **Four combine harvesters**:
Similarly, 4 combine harvesters can harvest:
- 4 harvesters * 160 acres per harvester = 640 acres.
3. **Twelve combine harvesters**:
Similarly, 12 combine harvesters can harvest:
- 12 harvesters * 160 acres per harvester = 1920 acres.

Clare made $160 babysitting last summer. She put the money in a saving account that pays 3% interest per year. If Clare doesn't touch the money in her account, she can find the amount she'll have the next year by multiplying her current amount by 1.03. (A) How much momey will Clare have in her account after 1 year? After 2 years? (B) How much momey will Clare have in her account after 5 years? Explain your reasoning. (C) Write an expression for the amount of money Clare would have after 30 years if she never withdraws money from the account.
Solution-
Clare made $160 babysitting last summer. She put the money in a saving account that pays 3% interest per year.
It is a condition of compound interest with annually compounding.
We know that,
[tex]P'=P(1+r)^n[/tex]
Where,
P' = the money she will be getting after n years,
P = the money she deposited = $160
r = annual rate of interest = 3% = 0.03
n = number of years
Money she will be getting after 1 year
[tex]\Rightarrow P'=160(1+0.03)^1=160\times 1.03=\$164.8[/tex]
This is why when she multiply 1.03 with her current amount, she gets the amount she will be getting after one year.
Money she will be getting after 2 year
Taking current balance as $164.8 as at the end of one year it will be the base amount on which interest will be calculated,
[tex]\Rightarrow P'=168.8(1+0.03)^1=168.8\times 1.03=\$169.74[/tex]
Again by multiplying 1.03 she can get the amount of money she will be getting next year.
Money she will be getting after 5 year
P' = the money she will be getting after 5 years,
P = the money she deposited = $160
r = annual rate of interest = 3% = 0.03
n = 5
Putting the values,
[tex]\Rightarrow P'=160(1+0.03)^5=160\times 1.1593=\$185.49[/tex]
She will be getting $185.49 after 5 years.
We can also do this by calculating the amount of money she will be getting at the end of each year and multiplying it with 1.03 in order to get the amount of money she will be getting the next year.
Expression for the amount of money Clare would have after 30 years if she never withdraws money from the account-
[tex]\Rightarrow P'=160(1+0.03)^30[/tex]
This is the expression for the desired condition.
The amount of money Clare would have in her account after one year is $164.80.
The amount of money Clare would have in her account after two years is $169.74
The amount of money Clare would have in her account after five years is $185.48.
The expression that can be used to determine the amount of money Clare would have in her account after 30 years is 160(1.03^30)
How much would Clare have in her account?The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value P = Present value R = interest rate N = number of yearsBalance after one year = 160 x (1.03) = $164.80
Balance after five years = 160 x (1.03^5) = 185.48
Balance after two years = 160 x (1.03^2) = 169.74

5 + 62 = 18p - 10p
67 = 8p
p = 67:8
p = 67/8 or 8.375
Answer:
p = -8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10p + 5 = 18p −6/2
10p + 5 = 9p + −3(Distribute)
10p + 5 = 9p − 3
Step 2: Subtract 9p from both sides.
10p + 5 − 9p = 9p − 3 − 9p
p + 5 = −3
Step 3: Subtract 5 from both sides.
p + 5 − 5 = −3 − 5
p = −8

Section a of a theater contains 12 rows of 15 seats each section b contains only 10 rows but had the same number of seats as section a
The question involves understanding multiplication and division principles. Section A has 180 seats in total (12 rows * 15 seats). Section B, having the same total number of seats but only 10 rows, would have 18 seats per row.
Explanation:The question involves the basic principles of mathematics, specifically dealing with multiplication and division concepts. Section A of the theater has 12 rows of 15 seats each, which totals to 180 seats (12 * 15 = 180). As it is stated that Section B has the same number of seats as Section A but only consists of 10 rows, each row in Section B must, therefore, contain 18 seats (180 / 10 = 18).
This is an application of the principle that if a total quantity remains the same, and it is divided into fewer groups, then each group will contain more than before. Therefore, even though Section B has fewer rows than Section A, each row in Section B contains more seats, leading to the same total.

There are 18 seats in each row of Section B.
To find out how many seats are in each row of Section B, let's first calculate the total number of seats in Section A:
Total seats in Section A = 12 rows × 15 seats per row = 180 seats
Since Section B has the same total number of seats as Section A but only 10 rows, we can find out how many seats are in each row of Section B by dividing the total number of seats in Section B by the number of rows in Section B:
Seats per row in Section B = Total seats in Section B / Number of rows in Section B
We already know the total seats in Section B is 180, and the number of rows in Section B is 10.
Let's plug these values into the formula:
Seats per row in Section B = 180 seats / 10 rows = 18 seats
The complete question is-
In a theater, Section A contains 12 rows of 15 seats each. Section B has the same total number of seats as Section A but contains only 10 rows. How many seats are in each row of Section B?

what else would need to be congruent to show that ABC = DEF by SAS?
The answer us A.
Line AC needs to be congruent to DF because for SAS (side angle side) we have a side (BA and DE) and an angle (A and D) so we need another side.
Answer:
A. [tex]\overline{AC}\cong \overline{DF}[/tex].
Step-by-step explanation:
We have been given image of two triangles ABC and DEF. We are asked to find the information that will show that both triangles are congruent by SAS.
We know that two triangles are congruent by Side-Angle-Side congruence, if two sides and included angle of a triangle is equal to two sides and included angle of the other triangle.
We can see that angle A is included angle of side AB and AC, while angle D is included angle of side DE and DF.
We have been given that angle A is congruent to angle D and side AB is congruent to side DE.
To be both triangles congruent by SAS congruence, side AC must be congruent to side DF, therefore, option A is the correct choice.

Answer: Each multiple choice question is worth 5 points.
Step-by-step explanation: You can find this answer by using the equation "14m + 24 = 16m + 14" and then solving for "m". To find what "m" is, you must first subtract 14m from both sides, leaving "24 = 2m + 14". Next, you subtract 14 from both sides, leaving "10 = 2m". Finally, you divide both sides by 2, which will give you "m = 5". Thus meaning each multiple choice question is worth 5 points.
To check this, simply fill in for "m" and solve each side. 14 * 5 + 24 = 94 and 16 * 5 + 14 = 94. 94 = 94, so "m = 5" is correct.
