De’Shaun is 5 years younger than Nemo. Adela is twice as old as Nemo. Jefferson is 3 times as old as De’Shaun. Altogether their ages total 50. Find each person’s age

Answers

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

A mountain road rises 10 feet over a 206-foot run. What is its slope?

Answers

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.

Answers

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,

I think the answer might be 141 baked goods. but I dont know don't trust me.

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.

The total area of the polygon is 176 square feet. Find the value of x. x= ft

Answers

Answer:

x = 6 ft

Step-by-step explanation:

Area of the polygon = area of the square + 2(area of the triangle)

Area of the polygon = 176 ft²

Area of the square = length × width = 16 × 8 = 128

Area of the two triangles = 2(½*base*height) 2(½*x*8) = 8x

Plug in the above values into the equation for area of the polygon. Thus:

176 = 128 + 8x

Subtract 128 from each side

176 - 128 = 8x

48 = 8x

Divide both sides by 8

what is 903 minus 538​

Answers

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.

Answers

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)

maria spent 4/7 of money on books,1/5 of it on a pen and 1/14 of it on a newspaper. She has left 220 naira. How much did she originally have?

Answers

Let the x be the amount of money Maria had.
3/7 + 1/4 + 1/8 = 45/56
She spend 45/56 of x.
∴ 45/56 × x = (45/56)x
1 - 45/56 = 11/56
(11/56)x is the money that was left.
This is equivalent to 11.
(11/56)x = 11
11x = 11×56
11x = 616
x = 616/11
= 56.
Maria had #56.
