** its timed **how can ari simplify the following expression? ((5)/(a-3)-4)/(2+(1)/(a-3)) write the numerator and denominator with a common denominator. then divide the numerator by the denominator. to do this, multiply the numerator by the reciprocal of the denominator. write the numerator and denominator with a common denominator. then divide the numerator by the denominator. to do this, multiply the numerators and multiply the denominators. divide the numerator and the denominator by a – 3. then divide the numerator by the denominator. divide the numerator and the denominator by a – 3. then simplify the numerator and simplify the denominator.

we have

we know that

Step

Write the numerator and denominator with a common denominator

Numerator

Denominator

Step

Divide the numerator by the denominator

To do this, multiply the numerator by the reciprocal of the denominator.

therefore

the answer is the option

Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerator by the reciprocal of the denominator

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
