The number is equal to 25.

To write the word problem as an algebraic equation:

In this exercise, we are required to translate the word problem into a mathematical (algebraic) expression and solve for the unknown variable (number):

Translating the word problem into an algebraic expression, we have;

A number is doubled and then increased by 20:

[tex]2n + 20[/tex]   ...equation 1.

The result is 5 less than 3 times the number:

Answer:

(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Step-by-step explanation:

B. False

they cannot be written as 10xy but only in 5x+5y

x and y will only become together if they are multiplied

as you can see there's a plus sign

you can add them if it is in 5x+5x (or) 5y+5y but never as in 5x+5y

Answer:

  6 11/32

Step-by-step explanation:

The two cans of broth used in the recipe total 2·14.5 oz = 29 oz. The number of people John wants to serve is 28/4 = 7 times the number served by one recipe. So, the amount of broth needed is ...

  (29 oz)·7 = 203 oz

Each quart container of broth holds 32 oz, so John will need ...

  (203 oz)/(32 oz/container) = 6 11/32 containers

John needs 6 11/32 containers of broth.

_____

If John must buy the broth, he must buy 7 containers. he will have 21/32 of a container left over after making his soup.

Step-by-step explanation:

slope= change of y/ change of x

Answer:

Hello, It isn't clear.

It looks blur to me

Answer:

7. C

8. A

To find slope, we need two points. Once we have them, we can put them into the formula:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]      ← this is rise/run

For 7, it's just a matter of comparing any two consecutive points.

For 8, you are given the two points.

The answer is [tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]

First, you must flip the equation

[tex]12k+29[/tex] ≥ [tex]120[/tex]

Then, you must subtract 29 on both sides

[tex]12k[/tex] ≥ [tex]91[/tex]

Finally, divide both sides by 12

[tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]

Answer:

[tex]b = 8[/tex]

Step-by-step explanation:

First, cross multiply across the equal sign. Note that what you do to one side, you do to the other:

[tex](b+10)(2b-7)(\frac{8}{b+10}) = (\frac{4}{2b -7})(b+10)(2b-7)\\ \\(2b -7)(8) = (4)(b+10)[/tex]

Next, distribute 8 and 4 to their corresponding parenthesis:

[tex]8(2b -7) = 16b - 56\\4(b + 10) = 4b + 40[/tex]

[tex]16b - 56 = 4b + 40[/tex]

Next, isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 56 and subtract 4b from both sides:

[tex]16b (-4b) - 56 (+56) = 4b (-4b) + 40 (+56)\\16b - 4b = 40 + 56\\12b = 96[/tex]

Isolate the variable, b. Divide 12 from both sides:

[tex]12b = 96\\\frac{12b}{12} = \frac{96}{12} \\b = \frac{96}{12} \\b = 8[/tex]

[tex]b = 8[/tex] is your answer.

Answer:

185

Step-by-step explanation:

Answer:

It entirely depends upon an individual.

It’s a known fact that humans need social interaction. Lack of which can affect their social behaviour and mindset. Whilst most would agree that e-learning is widely preferred by the younger generation, it is undeniably detaching them from social interactions.

When kids or students are engrossed in learning online, they’re missing out on social interactions that can open various doors of the mind, be it creative or observational skills. It’s understood that e-learning allows an individual to study far and beyond the subject and gives them an opportunity to explore multiple fields of their interest, one can’t ignore that it chains them to the system as well.

The deal-breaker in such a situation is an individual. If they demand social interaction, they would keep their digital device aside for once and would get indulge in social interaction. If they’re of another kind, they would prefer spending their days and nights just exploring and reading about new things online.

So, in my opinion, it’s quite subjective to narrow down the overall benefits and drawbacks of e-learning.

Answer:

Step-by-step explanation:

The i is usually the square root of -1 which does not exist in the real number system.

The number given is a mixture of real and complex and is classified as complex.

The answer is C

Answer:

the answer is: C,Complex

Step-by-step explanation:

Complex Numbers

A Complex Numbers is a combination of a real number and an imaginary number in the form a + bi. The real part is a, and b is called the imaginary part.

Examples include 4 + 6i, 2 + (-5)i, (often written as 2 - 5i), 3.2 + 0i, and 0 + 2i.

Note the last two examples:

3.2 + 0i is just the real number 3.2. All real numbers are complex numbers with zero for the imaginary part.

0 + 2i is just the imaginary number 2i. All imaginary numbers are complex numbers with zero for the real part.

Answer:

Step-by-step explanation:

In this problem we will estimate her monthly earnings

given that she earns $13.05 per hour

and also given that she works for 190 hours in a month

then in a month, her earnings will be

=$13.05*190

=$2479.5

alternatively,

per week she works 47.5hours

in a week she will earn 13.05*47.7= $622.485

4 weeks make a month

then after one month her earning will be

$622.485*4= $2479.5

Answer:

x = [tex]\frac{4}{3}[/tex]  

Step-by-step explanation:

Rectangle:

Length = 3x feet

Width = 4 feet

Perimeter = 2*(length +width)

                = 2* (3x + 4)

                = 2*3x + 2*4

                 = 6x + 8

Area = length * width

        = 3x * 4

        = 12x

Area of rectangle =  perimeter of rectangle

                       12x = 6x + 8              {Subtract 6x form both sides}

               12x - 6x  = 8

                       6x = 8                    {Divide both sides by 6}

                         x = 8/6

Answer:

x = 5 1/3

Step-by-step explanation:

6 = x + 2/3

-2/3 -2/3

5 1/3 = x

Answer:

[tex]\boxed {x = \frac{16}{3}}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]6 = x + \frac{2}{3}[/tex]

-Switch sides:

[tex]6 = x + \frac{2}{3}[/tex]

[tex]x + \frac{2}{3} = 6[/tex]

-Subtract [tex]\frac{2}{3}[/tex] to both sides and convert 6 to a fraction:

[tex]x + \frac{2}{3} - \frac{2}{3}= 6 - \frac{2}{3}[/tex]

[tex]x = \frac{18}{3} - \frac{2}{3}[/tex]

-Since both fractions have the same denominator, then you subtract the numerators:

[tex]x = \frac{18 - 2}{3}[/tex]

[tex]\boxed {x = \frac{16}{3}}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]\frac{16}{3}[/tex].
