Answer:

  7/5x -1/3

Step-by-step explanation:

We assume you want to simplify this expression.

  [tex]\dfrac{-3}{5}x-\dfrac{1}{4}\cdot\left(-8x+\dfrac{5}{6}\right)-\dfrac{1}{8}\\\\=-\dfrac{3}{5}x+\left(-\dfrac{1}{4}\right)\cdot(-8x)+\left(-\dfrac{1}{4}\right)\cdot\left(\dfrac{5}{6}\right)-\dfrac{1}{8}\\\\=\left(-\dfrac{3}{5}+2\right)x-\left(\dfrac{5}{24}+\dfrac{1}{8}\right)\\\\=\dfrac{7}{5}x-\dfrac{5+3}{24}=\boxed{\dfrac{7}{5}x-\dfrac{1}{3}}[/tex]

2 = 10/5; 1/8 = 3/24; 8/24 = 1/3. The x-terms get combined and the constants get combined. It is generally helpful to eliminate parentheses first using the distributive property.

Answer:

x=50

Step-by-step explanation:

1. equal the equations to each other: 2(x+10)=3x-30

2. distribute the 2 to x+10: 2x+20=3x-30

3. subtract 2x from both sides, and add 30 to both sides: x=50

Answer:

10 years

Hence, it will take 10 years for the sum of money to double itself with the rate of 10% per annum simple interest. Note: While solving questions related to principal interest, it is important to keep in mind that simple interest calculated from the formula, Simple Interest (I) = P × R × t 100, doesn’t represent the total amount of money.

Answer:3 9/11

Step-by-step explanation:

First we need to convert both numbers to mixed numerals. Just search it up on the internet if ur dont know how to do that. Then once you have them both, 21/2 and 11/4, you divide the fractions (multiply by reciprocal) and you get 42/11. reconvert back to mixed numeral and u get 3 9/11

Answer:

"The ratio of the number of cats to dogs is 3:5. How many dogs would there be if there were 12 cats?"

Reworded, this says that "for every 3 cats there are 5 dogs."  Or else you could say, "for every 5 dogs there are 3 cats."

You are given the number of cats=12.  For every 3 cats there are 5 dogs."  That means 50 dogs.

 (3 cats) / (5 dogs) = (12 cats) / (x dogs)

  3 / 5 = 12 / x

   3x = 5*12

    3x = 60

      x = 20 dogs

Or you could write:

  (5 dogs) / (3 cats) = (x dogs) / (12 cats)

    x = 20 dogs.

Step-by-step explanation:

An ordered pair of numbers a and b, written as a / b, is a ratio if b is not equal to 0.To start the room contained 20 dogs.

Mathematicians use the term "ratio" to compare two or more numbers. It serves as a comparison tool to show how big or tiny an amount is in relation to another. Two quantities are compared using division in a ratio. In this case, the dividend is referred to as the "antecedent" and the divisor as the "consequent."

According to a revised version, "there are 5 dogs for every 3 cats." Alternatively, you may say, "There are 3 cats for every 5 dogs."

You are informed that there are 12 cats. There are 5 dogs for every 3 cats. That's fifty dogs.

3 cats divided by 5 dogs equals 12 cats (x dogs)

3 / 5 = 12 / x

3x = 5*12

3x = 60

x = 20 dogs

Answer:

10.2 as a fraction is 10.2/1.

Step-by-step explanation:

Basically you keep the numerator and have 1 as your denominator.

The fraction for the given decimal number is [tex]10\frac{1}{5}[/tex].

The given decimal number is 10.2.

Fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Here, in the decimal number 10.2, after decimal point there is one digit.

So, divide 102 by 10.

Now, 10.2 = 102/10

= 51/5

= [tex]10\frac{1}{5}[/tex]

Therefore, the fraction for the given decimal number is [tex]10\frac{1}{5}[/tex].

Hello there!

These numbers are called reciprocals.

A reciprocal is a number flopped over.

Answer:

$11091.23

Step-by-step explanation:

Reword the situation:

She purchased a car for 18791 dollars 39 months ago.

As the 39 months passed she has been paying 197.43 a month.

How much does she still owe for her car?

First find out how much she's paid so far.

For 39 months she has been paying 197.43 a month

So, so far she's payed a total of 197.43 * 39 = 7699.77 dollars

Now subtract amount she's paid so far from total price of car.

18791 - 7699.77 = 11091.23

She still owes 11091.23

Answer:

Do the same thing for the other exercises and you should find the results. They are all complimentary angles, that means if you sum the two equations representing the angles of each exercise they will be equal to 180º always

Step-by-step explanation:

3. notice 2x is complimentary of 2x + 80 because 2x is opposed to that blank space that compliments it.... I'm bad at explaining, I'll just show.

2x + 2x + 80 = 180

4x + 80 = 180

4x = 180 - 80

4x = 100

x = 25º

so then:

2x = 2*25

2x = 50º

and:

2x + 80 = 50 + 80

2x + 80 = 130º

hope you get it right

Answer:

The answer would be 53 meters below the surface

Step-by-step explanation:

If Chris is at -40 meters (meaning that he is 40 meters under the surface or, zero.) You would subtract 13 from that original depth of -40 in order to get -53 meters below the surface or 53 meters deep.
