Error analysis describe and correct the error
student made when solving. kx + 3x = 4 for x.

kx + 3x = 4
kx + 3x - 3x = 4 - 3x
kx=4 - 3x
- 3x
x = 4*3* x

Solving

for x

Step-by-step explanation:

here the student leave 'x' in both sides

The error is not notice the factor is the 'x'

So:

Is the best way to solving to 'x' 'k' maybe is knowing o is a constant

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
