Six more than three times a number is less than or equal to 96. d. Five less then half the distance from Jerod’ s home to the ma
ozzi

First statement : Six more than three times a number is less than or equal to 96.

Let us assume number be n.

We can repharse above statement as :

"6 more than 3 times of n is less than or equal to 96".

Therefore, we can write an ineuality as.

3 times of n = 3n

6 more than 3 times of n = 3n+6.

3n+6 ≤ 96.

_____________________________________________________________

Statement 2: Five less then half the distance from Jerod’ s home to the mall is more then 6 miles.

Let us distance from Jerod’ s home to the mall is d.

We can repharse above statement as:

5 less than 1/2 of d is more than 6 miles.

5 less than 1/2 of d = 1/2d -5 .

Therefore, we can write an ineuality as.

12d -5 > 6.

1/3 in division form
marusya05 [52]

Answer:

Remember, 3 is the same thing as 3/1. Before we can divide, we need to make one more change. We'll switch the numerator and the denominator of the fraction we're dividing by: 1/3 in this example. So 1/3 becomes 3/1.

Step-by-step explanation:
