Step-by-step explanation:

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

Answer:

Yes

Step-by-step explanation:

The relation is a function. For a relation to be a function there must be a unique x value for each y value. So this means x's can not repeat, and in this relation, the x-values never repeat. Therefore this is a function.

∆HGJ is isosceles

hence, angleH = angle J

8x = 6x + 18

8x - 6x = 18

2x = 18

x = 18/2

x = 9

angleH = 8x = 8×9 = 72

angleH =72°

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: No. Zeke found the LCM to be the product of two and eight but because eight is a multiple of two the LCM is eight so the first day he will have both clubs is the 8th day of the month

Step-by-step explanation:

all you have to do is fine the least common multiple of 2 and 8 which is eight so obviously zeke is incorrect because they said the least common multiple was 16 and it is not. zeke multiplied 2 and 8 which is not what you’re supposed to do to get the lcm.

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.

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.

Answer:

The amount of markup is 88 dollars.

Step-by-step explanation:

Given that the whole sale price of bicycle is: $400

[tex]P = \$400[/tex]

Mark up is the profit that the seller of the product makes after selling the product more in price more than its cost or buying price.

Given that mark up percentage is 22%

It can be written mathematically as:

[tex]Mark\ up = 22\%\ of\ Price\\Mark\ up = 0.22 * P\\Mark\ up = 0.22 * 400\\= \$88[/tex]

Hence,

The amount of markup is 88 dollars.

the answer is 5/3

Answer:

it would be 5/3 or 1 2/3

Step-by-step explanation:

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.
