Determine which method would be more efficient for solving: Rewriting and using the distributive property or dividing. Solve eac
liq [111]

Answer:

A.  x = 3.03

B.  x = 4/3

Step-by-step explanation:

A.  2000 (x-0.03) = 6000 is quickly simplified byu dividing both sides by 2000:

(x - 0.03) = 3.  Removing the parentheses, we get:  x = -0.03 = 3, or x = 3.03.

B.  The distributive property is the faster method here.  We determine that the LCD is 12 and multiply both sides of this equation 1/4 (4+x) = 4/3 by 12:

3(4 + x) = 16

and then carry out the indicated multiplication:  12 + 3x = 16, or

3x = 4, or x = 4/3

Suppose the total cost for n tickets is $36 what's is the total cost of one more ticket is purchased
arsen [322]
$36/n because since there are n amount of tickets, you should divide $36 by n. I feel like you won't get me. For instance, let's say n is 6 tickets. So if 6 tickets are for $36, you should divide $36 by 6 tickets to find the unit rate. Hope this helps.
