Answer:
There are a lot of turning point in the history of algebra one of those is the discovery of the plain and the quadrants by Rene Descartes. This discovery paved way to a lot of knowledge which was later on use in solving other complicated mathematical problems.
Step-by-step explanation:
Answer:
B. (12-6) n - 50
Step-by-step explanation:
Given that:
Cost of making hat = $6 per hat
Selling price = $12 per hat
Advert cost = $50
Number of hats made = n
The profit or money raised from the sales of hat:
Total Revenue from sales - total cost of production - advert cost
Total Revenue from sales = ($12 * n) = $12n
Total cost of production = ($6 * n) = $6n
Advert cost = $50
Hence,
12n - (6n + 50)
12n - 6n - 50
(12 - 6)n - 50
Answer:
Step-by-step explanation:
<u>Point-slope form: </u>
- <em>y - y1 = m(x - x1)</em>
<u>Slope formula:</u>
- <em>m = (y2 - y1)/(x2 - x1)</em>
<u>Given points:</u>
<u>Finding the slope:</u>
- m = (13 - (-2))/(3 - 0)
- m = 15/3
- m = 5
<u>Using point 1</u>
- y - (-2) = 5(x - 0)
- y + 2 = 5x
Answer:
Step-by-step explanation:
Combine like terms: Like terms have same variable with same power and to combine the like terms, add/subtract the co efficient of the variables.
<h3>Perimeter:</h3>
Perimeter = sum of all sides
a) Perimeter of ΔABC = AB + BC + CA
= x + 14 + x + 14 + x + 14
= x + x + x + 14 + 14 + 14 {Combine like terms}
= 3x + 42
b) EF = DI - GH
= 2x + 3 - x
= 2x - x + 3
= x + 3
c) FG = HI - ED
= 12 + 2x - (x + 5)
= 12 + 2x - x - 5 {To open the brackets, (-1) is distributed to x and 5}
= 12 - 5 + 2x - x
= 7 + x
d) Perimeter of DEFGHI = DE + EF + FG + GH + HI + ID
= x + 5 + x + 3 + 7 +x + x + 12 +2x + 2x + 3
= x +x + x + x + 2x + 2x + 5 + 3 + 7 + 3 + 12
= 8x + 30
Answer:
15( b+ a) - 2(a + 0 ) = c
then
c+b = t
We could put the two together to make 15(b+a)- 2(a+0) + b = t
Where t = 8379.70
a= £249.99 b= 329.99
Step-by-step explanation:
Equal amounts are 8549.7 from 30 mowers a+b = small and large.
If we use this as an even and take away a+b at different equations we can find the answer to be 8379.70 on the 2nd equation. First equation = 8579.70
8549.7- 249.99-249.99+329.99 to equal the given year to find c in first equation and total in year = t within the above equation.
