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

151.5 miles
Step-by-step explanation:
50.5 × 3 = 151.5
Answer:
151.5 Miles
Step-by-step explanation:
A constant speed means the speed was the same throughout the whole trip, also meaning there were no stops. So the answer is as simple as 50.5x3

Please solve with elimination
5x + 9y =-5
3x -8y = -3
help I will give brainliest
please show work
Answer:
Step-by-step explanation:
5x+9y=-3 Multiply both sides by 8
40x+72y=-24
-53x-8y=-3 Multiply both sides by 9
-477x -72y= -27
sum the equations vertically to eliminate one variable
40x+72y= -24
-477x-72y= -27 (the y cancels out )
-477x =-51 (-24 + -27=-51)
-477x=-51 / -477 divide both sides by -477
x =51/437
5x 51/437=9y= -3 substitute the value of x
y= -174 /437
(x,y) = (51/437, -174/437)

Consider the line that passes through each pair of given points, and decide what type of slope the line has.
(2, 4) and (5, 1)
(-7, 8) and (-7,0)
(6,-3) and (-4,-3)
(3,5) and (-1,2)
Answer:
2.) undefined slope 3.) zero slope (i'm not sure what 1 and 4 are, sorry!)
Step-by-step explanation:
undefined slope has the same x-coordinate and the denominator becomes 0. it also is a vertical line. for a zero slope, it has the same y-coordinate and the numerator is 0. this is a horizontal line. *this is my first response so if i am wrong, that is embarrassing*

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.

Write the equation of the line that passes through the points (-8,-5) (5,−8)
Answer:
y=-3/13x-89/13
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-8)-(-5)/5-(-8)
m=-3/13
y-y=m(x-x1)
y-(-8)=-3/13(x-5)
y+8= -3/13x+15/13

goods Ella needs to sell in order to raise $125.00 after the cost of supplies?
HELP
Answer:
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.

Determine the range of the following graph:
Answer:
The range of the graph is [tex]Ran\{f\} = [-4, 11)[/tex].
Step-by-step explanation:
From Function Theory we identify the range of the function as the set of values on vertical axis (y-axis). According to the graphic, we find that the range of the following graph, which represents a bounded function, is:
[tex]Ran\{f\} = [-4, 11)[/tex]
The range of the graph is [tex]Ran\{f\} = [-4, 11)[/tex].
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
