1/3k+80=1/2k+120 k=??

Mathematics
1 answer:
zhenek [66]3 years ago
4 0

Answer:

here is your answer

Step-by-step explanation:

k = -240

<u>Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : </u>

1/3*k+80-(1/2*k+120)=0

<u>Simplify:</u>

1/2

    1                1

 ((—•k)+80)-((—•k)+120)  = 0

    3                2

<u>Rewrite the whole as a fraction using  2  as the denominator :</u>

             120             120 • 2

 120 =  ———  =  ———————

                1                     2  

<u>Equivalent fraction : The fraction thus generated looks different but has the same value as the whole</u>

<u>Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator</u>

Identify the coordinates of the point (3,-2), translated 5 units left and 6
kap26 [50]

Answer:

(- 2, 4 )

Step-by-step explanation:

A translation of 5 units left means subtract 5 from the original x- coordinate.

A translation of 6 units up means add 6 to the original y- coordinate.

Thus

(3, - 2 ) → (3- 5, - 2 + 6 ) → (- 2, 4 )
