To simplify the expression 2(x + 7) - 18x + 4/5, you distribute the 2 across (x + 7), then combine like terms to get the equivalent expression, which is -16x + 14 + 4/5.

The expression that is equivalent to 2(x + 7) - 18x + \(\frac{4}{5}\) can be simplified through the distributive property and combining like terms. First, distribute the 2 into the parentheses:

2(x) + 2(7) - 18x + \(\frac{4}{5}\)
= 2x + 14 - 18x + \(\frac{4}{5}\).

Next, combine like terms by subtracting 18x from 2x:
(2x - 18x) + 14 + \(\frac{4}{5}\)
= -16x + 14 + \(\frac{4}{5}\).

So the equivalent expression is -16x + 14 + \(\frac{4}{5}\).

211 to 1500

11 to 300

Step-by-step explanation:

1.8 to 9 = 18/90 = 1(18)/5(18) = 1/5 = 1 to 5

2.11 to 15 = 211/1500 = 211 to 1500

3.30 to 90 = 330/9000 = 110/3000 = 11/300 = 11 to 300

To determine the students selected to go to the board, start with the fourth student and then select every ninth student thereafter. Thus, the students chosen are the 4th, 13th, 22nd, and 31st students who enter the classroom.

The question involves determining which students a professor will select to go to the board based on a specific selection process. The professor decides to randomly select the fourth student who enters the classroom and every ninth student after that. To find out who these students are, we begin by identifying the fourth student initially. After the fourth student, every ninth student subsequently means we add 9 to the initial student's number to find the next student.

The fourth student who enters

The fourth student + 9 = the 13th student

The 13th student + 9 = the 22nd student

The 22nd student + 9 = the 31st student

Therefore, the students selected to go to the board are the 4th, 13th, 22nd, and 31st students who enter the classroom.

The students who will be going to the board are students 4, 9, 18, and 27.

Let’s determine the students who will be going to the board based on the professor’s selection criteria:

1. The fourth student who enters the classroom.

2. Every ninth student after that.

Let’s find the student numbers:

1. The fourth student corresponds to the 4th position.

2. The ninth student corresponds to the 9th position.

3. The 18th student corresponds to the ninth student after that (since 9 + 9 = 18).

4. The 27th student corresponds to the ninth student after the 18th student (since 18 + 9 = 27).

Therefore, the students who will be going to the board are students 4, 9, 18, and 27.

Seth's spending on jam can be represented by two expressions: 0.80*J*(b + s) and 4*(b + s). The calculations involve finding the total cost without the discount, finding the amount of the discount, and then subtracting the discount from the total cost.

Let's denote the price of one jar of jam as J, which is $5. The number of jars of blackberry jam that Seth bought is denoted as b, and the number of jars of strawberry jam as s. Without the discount, the total cost for all the jam he bought would be J*(b + s). Given that Ms. Wells offers a 20% discount for purchasing at least two jars of jam, Seth's actual spending would be

Answer:

The temperature at noon was 37 °F.

Step-by-step explanation:

Given:

Temperature at midnight is  34 °F.

Reduction in temperature by 6:00 a.m. is 8°. So, temperature after reduction is given as the difference in temperature at midnight and morning.

Therefore, temperature by 6:00 a.m. in the morning is given as:

Reduced temperature = Midnight temperature - Reduction in temperature.

Reduced temperature = 34 °F - 8 °F = 26 °F.

Now, by noon, the temperature is increased by 11 °F. Therefore, the final temperature by noon is addition of 11 degree to the temperature that was in the morning. Therefore,

Temperature at noon = Temperature in morning + Increase in temperature.

Temperature at noon = 26 °F + 11 °F = 37 °F.

So, the temperature at noon is a 3 °F increase to the temperature at midnight and is equal to 37 °F.

Emily's figurine is 17 inches taller than Chen's figurine

Step-by-step explanation:

Emily and Chen built clay figurines for art class

We need to find how much taller is Emily's figurine than Chen's in inches

To solve this problem we must to change the heights of the two figurines to inch

∵ Emily's figurine is 5' 1" tall ⇒ 5 feet and 1 inch

∵ 1 foot = 12 inches

∴ The height of Emily's figurine = 5(12) + 1

∴ The height of Emily's figurine = 60 + 1

∴ The height of Emily's figurine = 61 inches

∵ Chen's figurine is 3' 8" tall ⇒ 3 feet and 8 inches

∵ 1 foot = 12 inches

∴ The height of Chen's figurine = 3(12) + 8

∴ The height of Chen's figurine = 36 + 8

∴ The height of Chen's figurine = 44 inches

To find how much taller is Emily's figurine than Chen's in inches subtract their heights

∵ The difference between the two figurine = 61 - 44

∴ The difference between the two figurine = 17 inches

∴ Emily's figurine is 17 inches taller than Chen's figurine

Emily's figurine is 17 inches taller than Chen's figurine

Answer:

The second option is best to choose.

Step-by-step explanation:

Joshua plans on working 3 days a week for 8 weeks. Therefore, Joshua will work for (8 × 3) = 24 days.

For the first option, Joshua earns $20 each day he works. So, in 24 days he will earn (20 × 24) = $480.

For the second option, he earns one nickel for agreeing to work, and that amount doubles each day he works after that.

So, the total earning of Joshua after 24 days of work will be

0.05 + 0.1 + 0.2 + 0.4 + 0.8 + 1.6 + ......... up to 24 terms {Since 1 nickel is equal to $0.05}

Now, this is an G.P. series sum and first term is 0.05, common ration is 2 and the number of terms is 24.

So, the sum = [tex]0.05 \times \frac{2^{24} - 1 }{2 - 1}[/tex]

= $838860.75

Therefore, the second option is best to choose. (Answer)

Final answer:

To decide between the payment options, Joshua should calculate the total income for the first option ($480) and compare it to the exponentially growing total of the second option, which would be far greater due to the daily amount doubling. Therefore, the second option is the more lucrative choice.

Explanation:

The student's question pertains to determining which of the two payment options offered by Joshua's uncle for work on a soybean farm is more advantageous. Joshua needs to calculate the total earnings for each option over the course of 8 weeks, given that he will work 3 days each week. For option one, it is straightforward: $20 per day times 3 days per week times 8 weeks equals a total of $480. Option two, however, requires calculating the total amount for a doubling sequence starting with a nickel ($0.05).

For option two, the earnings for each week will look like this:

Week 1: Day 1 = $0.05, Day 2 = $0.10, Day 3 = $0.20

Week 2: Day 1 = $0.40, Day 2 = $0.80, Day 3 = $1.60
...and so on. The amount doubles each day Joshua works.

Calculating this for the 24 days (3 days times 8 weeks) will show that on day 24, Joshua's daily earnings would be $0.05 ×223 (since the first day is $0.05 and does not double).

Comparing the total earnings from both options will reveal that Joshua will earn significantly more with the second option. Therefore, Joshua should choose the second payment option.

Answer:

Speed of Vendelin is 60 kilometre per hour.

Step-by-step explanation:

Given:

The Distance two bus stops = [tex]\frac{3}{8}[/tex]

Speed of the bus =  60 km/h

To Find:

The Speed of  vendelin = ?

Solution:

Let the speed bof vendelin be x.  the it is stated that

" If Vendelin runs from home, he will be at the bus stop at the same time as bus."

So

Time Taken by the bus

=>[tex]\frac{ \text{ distance between the bus stop}}{\text{ speed of the bus}}[/tex]

=>[tex]\frac{\frac{3}{8}}{60}[/tex]

=>[tex]\frac{\frac{3}{8}}{\frac{1}{60}}[/tex]

=>[tex]\frac{3}{480}[/tex]------------------------------(1)

Time Taken by  Vendelin

=>[tex]\frac{ \text{ distance between the bus stop}}{\text{ speed of Vendelin }}[/tex]

=>[tex]\frac{\frac{3}{8}}{x}[/tex]

=>[tex]\frac{3}{8x}[/tex]----------------------------------(2)

Equating (1) and (2) we get

[tex]\frac{3}{480}[/tex] =  [tex]\frac{3}{8x}[/tex]

[tex]3 \times 8x = 3 \times 480[/tex]

[tex]3 \times 8x = 1440[/tex]

[tex] 8x =\frac{1440}{3}[/tex]

[tex] 8x = 480[/tex]
