** 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

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
