8k + 2m=3m +k solve for k

Veronika [31]

Answer: k= One- seventh of m.

Step-by-step explanation:

Given equation : 8k + 2m=3m +k ,where k and m are variables

To solve for k, Subtract 2m from both sides,we get

⇒8k+2m-2m=3m-2m+k

Simplify

⇒ 8k=m+k

Subtract k from both sides, we get

⇒ 8k-k=m+k-k

Simplify

⇒ 7k=m

Divide 7 from both the sides, we get

⇒ k=1/7m

⇒ k=one-seventh of m...........>here is the answer.

The correct question is
The raised vegetable garden in Susan's yard is in the shape of a rectangular prism with a volume of 48 cubic feet and a height of 3/4 foot. The base of the rectangular prism is not a square and the width is greater than 2 feet. What is the length and width of the rectangular prism?

let
x-------> the length of the base of the rectangular prism
y-------> the width of the base of the rectangular prism

we know that
volume of the prism=area of the base*height
volume=48 ft³
height of the prism=3/4 ft

area of the base=volume/height--------> 48/(3/4)---> 48*4/3----> 64 ft²

area of the base=64 ft²
area of the base=x*y
64=x*y--------> equation 1

y=x+2--------> equation 2

substitute equation 2 in equation 1
64=x*[x+2]-----> 64=x²+2x------> x²+2x-64=0

using a graph tool----> to resolve the second order equation
see the attached figure

the solution is
x=7.062 ft
y=x+2-----> y=7.062+2-----> y=9.062 ft

the answer is
the length of the base of the rectangular prism is 7.062 ft
the width of the base of the rectangular prism is 9.062 ft
