A mixed number looks like this: a(b/c)
The improper fraction currently looks like this: (ab/c)
Round the numerator to something you can divide by the denominator. For example, 45 would be rounded to 42. 42/7=6. 6 would be the whole number.
45-42=3. 3/7 is the new fraction.
So the answer for c is 6(3/7)
Do you know how to do d?

Answer:

x = ± 7

Step-by-step explanation:

Given

(2x - 1)(3x + 2) = x + 292 ← expand left side using FOIL

6x² + x - 2 = x + 292 ( subtract x from both sides )

6x² - 2 = 292 ( add 2 to both sides )

6x² = 294 ( divide both sides by 6 )

x² = 49 ( take the square root of both sides )

x = ± 7

That is x = - 7, x = 7

15 percent

Step-by-step explanation: You will substract the new value from the old value.

23-20

Now you will get the difference between them and divide that by the original amount.

3/20

This will equal 0.15 in which you now multiply by 100
