24 and 2/5=24+2/5
24=24
0.1=1/10
2/5=x/10
times both sides by 10
20/5=x
4=x
2/5=4/10=0.4
24 and 2/5=24+0.4=24.4
First you want to write 7x as a sum or difference: 15x-8x
Now, the expression would look like this: 10x^2+15x-8x-12
Next, factor out the 5x and -4 from the expression: 5x(2x+3)-4(2x+3)
Now, factor out the 2x+3 from the expression and you have your answer:
(2x+3)(5x-4)
Answer:

Step-by-step explanation:
To rationalize the denominator, you need to multiply the numerator and denominator by the radical in the denominator (aka. a factor of 1):

Answer:
2 /10
Step-by-step explanation:
The portion of the book that weight 2 1/8
Total number of books = 10
Number of books that weight 2 1/8 = 2
Fraction of book that weigh 2 1/8 = number of books that weigh 2 1/8 / total number of books
Fraction = 2 / 10
