The sum of three consecutive terms in an arithmetic sequence is 27, and their product is 585. find the three terms.

sammy [17]

$\text{the three consecutive terms in an arithmetic sequence}\\a;\ a+d;\ a+2d\\\\\text{system of equals}\\\\ \left\{\begin{array}{ccc}a+a+d+a+2d=27\\a(a+d)(a+2d)=585\end{array}\right\\ \left\{\begin{array}{ccc}3a+3d=27&|:3\\a(a+d)(a+2d)=585\end{array}\right\\ \left\{\begin{array}{ccc}a+d=9&\to d=9-a\\a(a+d)(a+2d)=585\end{array}\right\\$
$\text{substitute to the second equation}\\\\a(a+9-a)(a+2(9-a))=585\\\\a(9)(a+18-2a)=585\\9a(18-a)=585\ \ \ |:9\\a(18-a)=65\\18a-a^2=65\ \ \ |\text{change the signs}\\a^2-18a=-65\\a^2-2a\cdot9=-65\ \ \ |+9^2\\\underbrace{a^2-2a\cdot9+9^2}_{(a-b)^2=a^2-2ab+b^2}=-65+9^2\\(a-9)^2=16\to a-9\pm\sqrt{16}\\a-9=-4\ \vee\ a-9=4\ \ \ |+9\\a=5\ \vee\ a=13\\\\d=9-5=4\ \vee\ d=9-13=-4$

Can someone please help me ☹️

Vadim26 [7]

Answer:

When c = 6 and d = 34, there is one solution. When c = 8 and d = 6, there is no solution. When c = 8 and d = 12, there are infinitely many solutions.

Step-by-step explanation:

6x + 34 = 8x +12

-6x -6x

34 = 2x +12

-12 -12

22 = 2x

11 = x

8x + 6 = 8x +12

-8x -8x

6 = 12

No solution

8x+12= 8x + 12

-8x-12 -8x - 12

0 = 0

Infinite solutions

a local hamburger shop sold a total of 424 hamburgers and cheeseburgers. the number of cheeseburgers sold was three times the nu

Vedmedyk [2.9K]

Answer:

There were 318 cheeseburgers sold and 106 hamburgers sold.

Step-by-step explanation:

h = hamburgers

c = cheeseburgers

C = 3h

An equation would be: 424 = 3h + h.

424 = 3h + h

424 = 4h Add 3h and h together

106 = h Divide both sides by 4

106 x 3 = 318 This is cheeseburgers sold

Checking:

C = 3h

318 = 3h Divide both sides by 3

106 = h

Hope this helps,
