What is the answer X/7-3>8
mamaluj [8]

Answer:

x > 77

Step-by-step explanation:

According to order of operations rules, we must carry out division before addition or subtraction.  In this case we wish to isolate x and are permitted to simplify the inequality by combining the "like terms" 3 and 8, as follows:

X/7-3>8

     +3 +3

--------------

x/7 > 11

The easiest way in which to solve for x is to multiply both sides of this inequality by 7:

7(x/7) > 7(11), or

x > 77

All numbers greater than 77 are part of the solution set.

Six students eat 6 apples in 33 seconds. How long will it take nine students to eat 19 apples, if they don't cut apples into par
stepladder [879]

Answer: 104.5 seconds

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

Six students eat 6 apples in 33 seconds.

The proportion is: number of apples eaten /time

6 apples /33 seconds = 6/33

For 19 apples:

19 apples / x seconds =19/x

6/33 = 19/x

Solving for x:

x = 19 / ( 6/33)

x = 104.5 seconds
