Evaluate the expression 14x + y when x = 11 and y = 20.

Answers

Answer 1

Evaluating an expression just means to replace x by its value and y by its value and do some calculus.
By hypothesis, x = 11 and y = 20.

So in the expression 14x + y, you just replace x by 11 and y by 20.
14x + y = 14 * 11 + 20 = 154 + 20 = 174

Hope this helps! :)

Answer 2

Substitute the value of the variable into the expression and simplify.

174

Daniel's basic cell phone rate each month is $29.95. Add to that $5.95 for voice mail and $2.95 for text messaging. This past month Daniel spent an additional C dollars on long distance. His total bill was $62.35. How much did Daniel spend on long distance?

Answers

5.95 + 2.95 = 8.9
8.9 + 29.95 = 38.85
62.35 - 38.85 = 23.5
So Daniel spent $23.50 on long distance calling

Answer: Daniel spent $23.5 on long distance

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given.

So, Daniel's total bill (62.35) is equal to the sum of the cost of all the services: Basic cell phone rate (29.95); voice mail (5.95); text messaging (2.95); long distance (C)

Mathematically speaking:

29.95+5.95+2.95+C = 62.35

Solving for C

38.85+C =62.35

C =62.35-38.85

C =$23.5

Daniel spent $23.5 on long distance

A crack in a water main pipe leaks 7 gallons of water each hour. What volume of water has moved though the crack after 9 hours?

Answers

63 gallons of water. y=7h
7=7(9)

So if we know that 7 gallons of water goes through the pipe every hour, and we want to find how much water goes through the pipe after 9, we want to say,

7 gallons of water 9 times because there are 9 hours.

7 gallons of water 9 times is basically 7 * 9, or 63.

So 63 gallons of water has moved through the crack after 9 hours.

A computer sells for $430 which is 75% reduction of the original price. What is the original price of the computer?

Answers

Divide 430 by 75 to get 1% of the price.
430 / 75 = 5.733333...
Multiply that answer by 100 to get the original price.
5.73333... x 100 = 573.3333...
That will be your answer.

To double check your work, you can multiply 573.333... by 75 to see if the number in the problem (which was 75% of the original price) matches.
573.3333... x 75 = 430.

On the first day of the year, you have $700 in your bank account. You spend $35 per week. Your friend starts the year with $450 in his bank account. He saves $15 per week.

Solve the equation 700 – 35w = 450 + 15w to find out how many weeks, w, it will take for you and your friend have the same amount of money in your accounts.

Answers

A number of weeks are 5.

So this is just a basic algebra equation where we need to solve for an unknown variable.

First we should put all the w's on one side and regular numbers on the other, so:

250 = 50w

If we divide by 50 on both sides, we get:

w = 5

It will take 5 weeks for you and your friend to have the same amount of money in your back accounts.

Answers

It would be the last set of data. You can tell this because when put in ascending order, 26 is the minimum and 38 is the maximum. Here, you find the median and then to find the first quartile and third quartile points, you find the median of the first half and the second half.

Q1= the half point between the minimum and the median

Q3= the half point between the median and the maximum.

By doing this, it should match up to the box and whisker plot

The dataset that can be used for box-and-whisker plot is 27, 35, 35, 32, 26, 34, 36, 27, 38.

What is the data set?

A box plot is used to study the distribution and level of a set of scores. The whiskers represent the minimum value and the maximum value.

On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.

Minimum value = 26

Maximum value = 38

Q1 = 27

Median = 34

Q3 = 35

As Mars revolves around the sun, it travels at a speed of approximately
15
miles per second. Convert this speed to miles per minute. At this speed, how many miles will Mars travel in
4
minutes? Do not round your answers.

Answers

Step 1: Multiply 15 and 60 that equals 900
Step 2: Now multiply 900 by 4 and that equals 3,600

So, Mars revolves around the sun 900 miles per minute. In four minutes mars would have traveled 3,600 miles every 4 minutes.

Final answer:

To convert Mars' speed from 15 miles per second to miles per minute, multiply by 60 to get 900 miles per minute. Multiplying this by 4 gives the distance Mars will travel in 4 minutes, which is 3600 miles.

Explanation:

As Mars revolves around the sun, it travels at a speed of approximately 15 miles per second. To convert this speed to miles per minute, you simply multiply by the number of seconds in a minute:

15 miles/second × 60 seconds/minute = 900 miles per minute.

At this speed, to find out how many miles Mars will travel in 4 minutes, you multiply Mars' speed in miles per minute by the number of minutes:

900 miles/minute × 4 minutes = 3600 miles.

Therefore, Mars will travel 3600 miles in 4 minutes at the speed of 15 miles per second.

How do you put the sentence "5 thumb drives have 9 gigabytes more capacity than 1 compact disk." into a linear equation?

Answers

Well, we should first decide on our variables. Let's replace "thumb drives" with the letter "t", and "compact disk" with the letter "c".

Now, to understand the sentence. "5 thumb drives have 9 gigabytes more capacity than 1 compact disk." So, what does that mean? Well, if a compact disk has 10 gigabytes of capacity, then I suppose 5 thumb drives would have 19 gigabytes of capacity all together. So, we're just adding +9.

Alright, so as a linear equation:
"5 thumb drives have 9 gigabytes more capacity than 1 compact disk"
5t = c + 9

Why do u think rates are usually written as unit rates

Answers

it simplifies it down to how many this happens in that if you know what i mean. like miles per hour. if a car drove 300 miles in 5 hours thats the rate. 300 to 5.. to simplify, divide 300 by 5. so youd know you were going 60 mph, and thats why unit rates are imprortant. do not copy this answer, change the words around a little bit

The rate usually written for the amount of things is changing in one unit.

What is the rate?

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

A rate in mathematics is the comparison of two related values expressed in different units. The numerator of the ratio indicates the rate of change in the other (dependent) factor if the base of the ratio is written as a cohesive block of one of these variables, and if it is assumed that this quantity may be modified systematically (i.e., is an independent variable).

The rate usually written for the amount of units anything in one unit of something.

Julia has been saving money for a new Tv. The Tv normally costs $340 but is on sale for 30% off. How much money does Julia need to buy the tv?

Answers

There are two ways that this can be done.
You could find 30% of the original value and subtract that from the original value:

340*0.3=102
340-102=238

OR

You can multiply the original cost by 70% (100%-30%)
340*0.7=238

But either way the amount Julia will need to pay is $238
