Nine less than a number is no more than 8 and is no less than 3
frozen [14]

9 - x < 8 => -x < 8 - 9 => -x < -1 => x > 1

9 - x > 3 => -x > 3 -9 => -x > -6 => x < 6

So the number is between 1 and 6, notation 1 < x < 6

Which graph shows the solution to the following inequality?<br>4d- 6 &lt; 18 <br>PLEASE HELP​
kenny6666 [7]

Answer:

answer a

Step-by-step explanation:

4d-6 < 18

  • Let's isolate d on one side of the equation. Ignore the inequality for now. We'll deal with that later.

4d-6=18\\4d-6+6=18+6\\4d=24\\\frac{4d}{4}=\frac{24}{4}\\ d=6

  • Now, I'm going to bring back the inequality or < symbol. I only removed it when simplifying and isolating d, but if this confuses you, just do your math and keep the inequality there.

d < 6

  • On a number line, this would include every number <em>less than </em>6, due to the < (less than) symbol. This disqualifies answers b and d because they are showing every number <em>greater than </em>6. But, how do we decide between answers a and c?
  • If a line has point at its beginning, 6, then that means that every number <em>less than or equal to</em> [ ≤ ] 6 is being shown, but our equation just says <em>less than </em>[ < ] 6, so answer a is our correct answer.

Solve the equation. Write your answer as an integer or simplified fraction.
saw5 [17]

<u>Corrected question :</u>

Solve the equation. Write your answer as an integer or simplified fraction.

  • 8n - 7 (n - 2) = 18

<u>Required Solution :</u>

The given equation,

  • 8n - 7 (n - 2) = 18

★ Multiplying -7 into (n - 2),

>> 8n - 7 × (n - 2) = 18

>> 8n - 7n + 14 = 18

★ On substracting 7n from 8n we gets,

>> n + 14 = 18

★ Now transposing 14 which is in L.H.S. into R.H.S. (Remember that sign would be . So 14 would be -14),

>> n = 18 - 14

>> n = 14

★ Therefore,

  • Value of n is 14.
