In order to figure out how much money she needs for her trip to the store, jessica has to solve this equation. 2(x+1)+1=5 she completes the problem as seen in the steps below. 2(x+1)+1=5 step 1: 2(x+1) = 4 step 2: (x+1) = 2 step 3: x = 3 this can't be right! she checks her solution and realizes the answer is x = 1. in which step did jessica make an error? a step 1. b step 2. c step 3. d all the steps are correct.

Step-by-step explanation:

The equation that Jessica wants to solve is

.

The steps of Jessica's solution are.

Step 1:

Step 2:

Step 3:

Now, if you observe Jessica's steps, you would find that steps 1 and 2 are correct, but step 3 is wrong, because the number 1 must past to the other side  as a negative number, as follows

Then, Jessica must subtract the numbers

That's why she was wrong. Her step 3 was incorrect.

Therefore, the right asnwer here is C. Step 3.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
