Answer:

92

Step-by-step explanation:

Let the number be x.

As per the question,

3/4x - 18 = 1/2x + 5

(4)3/4x - (4)18 = (4)1/2x + (4)5

3x - 72 = 2x + 20

x = 92

The number is 92.

The value of a bike depreciates by 20% each year<br> why after 2 years is it not reduced by 40%?
nordsb [41]
Because it will not be 40 percent of the original, since after 20 percent is gone, the next year itll be 20 percent of the product, instead of the original, so for example, if it was 100, it would go down to 80, and then the next year it would be 20 percent of 80, not 100

Answer:

D: x < 20

Step-by-step explanation:

-4x + 16 > -64

subtract 16 from both sides because you must isolate x.

-4x + 16 - 16 > -64 - 16

-4x > -80

Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...

-4x/ -4 < -80/ -4

        x < 20

(negative divided by a negative will result in a POSITIVE.)

Hope this helped... I truly apologize if this is wrong..
