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
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

Jane has saved 600 dollars in a college fund. She added money to the account over the next year and at the end of the year the account had 890 dollars. Write an equation to represent the amount she saved over the year.
Answer:
$290.00
Step-by-step explanation:
The equation would be 890-600=290 because if you subtract the base amount from the final savings it would give you how much she saved altogether.

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.

A mountain road rises 10 feet over a 206-foot run. What is its slope?
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:
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 total area of the polygon is 176 square feet. Find the value of x. x= ft
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
6 = x
x = 6 ft
Answer:
x=6ft

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.
