Which line shows the first error in the solution? 5(x-5)=15 (1) 5x-25=15 (2) 5x-25=15-25 (3) 5x= -10 (4) 5x/5 = -10/5 (5) x=-2 (6) answers: a. line 2 b line 3 c. line 4 d. line 5

Answer : B. line 3

5(x-5)=15 > 1

We remove the parenthesis by distributing 5 inside the parenthesis.

 5x - 25 = 15 > 2

To get rid of -25, add 25 on both sides

5x - 25 + 25 = 15 + 25 > 3

5x = 40  > 4

Divide by 5 on both sides

x = 8  

From the given options we can see that there is a error in line 3.

Instead of adding 25 , they subtracted 25

So line 3 shows the first error.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

-4
