Answer:

[tex]x=\frac{d+c}{a-b}[/tex]

Step-by-step explanation:

The equation is:

a x - c = b x + d

so we subtract b x from both sides to group the terms that contain x on the left:

a x - b x - c = d

add c to both sides to isolate the terms in x on the left:

a x - b x = d + c

extract "x" as common factor on the left:

x (a - b) = d + c

divide both sides by the quantity (a - b) to isolate the "x":

x = (d + c) / (a - b)

or:    [tex]x=\frac{d+c}{a-b}[/tex]

Answer:

The closet equivalent of the ratio of 'a' to 'c' is:

[tex]\frac{a}{c}=1.680\:[/tex]

Step-by-step explanation:

Given

i.e.

a=0.63x

i.e.

c=3/8x

Hence,

[tex]\frac{a}{c}=\frac{0.63x}{\frac{3}{8}x}[/tex]

[tex]\frac{a}{c}=1.680\:[/tex]

Thus, the closet equivalent of the ratio of 'a' to 'c' is:

[tex]\frac{a}{c}=1.680\:[/tex]

It's slope is 5/103  , by using simple calculation for slope.

What is slope?
In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent slope; the reason for this usage is unclear, but it can be found in O'Brien's (1844) and Todhunter's (1888) formulations of the equation for a straight line as "y = mx + b" and "y = mx + c," respectively. The ratio of the "vertical change" to the "horizontal change" among (any) two distinct points along a line is used to calculate slope. The ratio can also be written as a quotient (also known as "rise over run"), which gives the same number for each and every two distinct points on same line.

Mathematically, it's calculated as "rise over run".

Here,

Rise is given i.e. 10feet.

and foot-run=206.

So, slope = Rise/foot-run

                = 10/206

                = 5/103 .

Hence, slope = 5/103.

Answer:

Nemo: 10

De'Shaun: 5

Adela: 20

Jefferson: 15

Step-by-step explanation:

Let Nemo's age be x

De'Shaun's age= x-5

Adela's age= 2x

Jefferson's age= 3(x-5)

= 3x-15

x+x-5+2x+3x-15= 50

7x-20= 50

7x= 50+20

7x= 70

x= 10

Nemo's age= 10

De'Shaun's age= 10-5

= 5

Adela's age= 2(10)

= 20

Jefferson's age= 3(10)-15

= 30-15

= 15

Answer:

  Age of Nemo = 10  years

De'shaun's age =  5 years

  Adela's age    = 20 years

Jefferson's age =  15 years

Step-by-step explanation:

Age of Nemo = x years

So, De'shaun's age = x - 5

Adela's age    = 2*x = 2x

Jefferson's age  = 3* (x -5) = 3*x - 3*5 = 3x -15

Total age  = 50

x + x - 5 + 2x + 3x - 15  = 50   {Combine like terms}

x + x + 2x + 3x - 5 - 15 = 50

                    7x   - 20   = 50

                               7x = 50 + 20

                               7x = 70

                                 x =  70/7 = 10

                Age of Nemo = 10 years

De'shaun's age = 10 - 5  = 5 years

                Adela's age    = 2* 10 = 20 years

            Jefferson's age  =  3*10 -15 = 30 - 15  = 15 years

Step-by-step explanation:

Answer:

200.

Step-by-step explanation:

I know math. But if you want an explanation, here it is.

First, you have to add 25 to 125 because you're trying to gain 25 more dollars than 125 dollars to make up for the money you already spent. Next, you need to dive 150, the result of 125 plus 25, by .75 because you're trying to figure out how many goods you need to sell for .75 cents, to get 150 dollars. So, you do the division, and the answer is 200 dollars.

C. middle school grades

Step-by-step explanation:

Colleges want to see if students challenged themselves by taking rigorous courses, and they also want to know what kind of grades students were able to maintain. They also like to take into account the scores you get on standardized tests because these tests can give a relatively accurate idea of a student's mastery of certain subjects. The only thing they don't pay attention to are the grades you earned in middle school. Since these grades aren't very recent, they don't serve as an accurate measure of a student's academic ability, which is why colleges prefer to look at the grades a student earns during their time in high school.

Answer: Your answer is 365

Step-by-step explanation: Hoped this helped you. And have a wonderful day!!!

The final result of 903 - 538 is 365.

To subtract 538 from 903, you perform the following calculation:

903 - 538 = 365

To explain the process, you start with the number 903 (minuend) and subtract 538 (subtrahend) from it.

1. Begin with the units place: 3 - 8. Since 8 is greater than 3, you borrow 1 from the tens place. The units place becomes 3 + 10 (borrowed) - 8 = 5.

2. Move to the tens place: 0 (in 903) - 3 (borrowed) - 3 (from 538) = -6.

3. Lastly, the hundreds place: 9 - 5 (from 538) = 4.
