Malia solved an equation, as shown below:
step 1: 6x = 48
step 2: x = 48 – 6
step 3: x = 42
part a: is malia's solution correct or incorrect? if the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation.
part b: how many solutions will this equation have?

Part A- wrong step number 2 by Malia

Part B - Only 1 solution

Step-by-step explanation:

Given steps are :

Step 1: 6x = 48

Step 2: x = 48 – 6

Step 3: x = 42

Part A:

The second step is wrong. Malia subtracted 6 from 48, but she should not have done it. She should have divided both sides by 6, to get the value of 'x' which is 8.

The correct step should be :

Divide both sides by 6,

Part B:

The equation has only 1 solution.

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
