Ymorist [56]

Answer:

80 minutes

Step-by-step explanation:

Rate and Time are inverses of each other

First,

Elise Time = 12

and

Katherine Time = 2 * 12 = 24

Their rates would be (inverses):

Elise Rate = 1/12

Katherine Rate = 1/24

Together their rate is 1/12 + 1/24 = 3/24

Now, the inverse of this rate would be the time it takes to complete 1 bag together, that is:

(3/24) ^ -1 = 24/3 = 8 minutes

So, 10 bags would take them:

8 * 10 = 80 minutes

4(x-3)=2(3x+1) 2 solve for x

Katarina [22]

Hi there!

Th' Eqn. is :-

4 (x - 3) = 2 (3x + 1)

=> 4x - 12 = 2 (3x + 1)

=> 4x - 12 = 6x + 2

Combine th' like terms :-

=> 4x - 6x = 2 + 12

=> - 2x = 14

=> x = $\dfrac {- 14}{2}$

=> x = - 7

Hence, The required answer is : x = - 7

~ Hope it helps!
