The work of a student to solve the equation 4(2x − 4) = 8 + 2x + 8 is shown below: step 1: 4(2x − 4) = 8 + 2x + 8 step 2: 6x − 8 = 16 + 2x step 3: 6x − 2x = 16 + 8 step 4: 4x = 24 step 5: x = 6 in which step did the student first make an error and what is the correct step? step 2; 8x − 4 = 2(6 + x + 6) step 2; 8x − 16 = 16 + 2x step 3; 6x − 2x = 16 − 8 step 3; 6x + 2x = 16 + 8

Step-by-step explanation:

Here, The work of a student to solve the equation :

The steps for calculating the value of x are :

Step 1: 4(2x − 4) = 8 + 2x + 8  

Step 2: 6x − 8 = 16 + 2x  

Step 3: 6x − 2x = 16 + 8  

Step 4: 4x = 24  

Step 5: x = 6

Step 2 is incorrect, as the student instead of multiplying, adds the number as :

4(2x − 4) = 8 + 2x + 8  

Here, the correct step is :

8x − 16 = 16 + 2x

6 x = 32

x = 5.33

So, the error is in STEP 2 and the correct option is (b).

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
