Answer: 5 > k
Step-by-step explanation: When you're asked to solve an inequality like -45 < -9k, your goal should be the same as it was when solving equations which is to get <em>k</em> by itself on one side.
In this problem since <em>k</em> is being multiplied by -9 on the right side of the inequality, to get <em>k</em> by itself, we divide both sides by -9 but here is the rule you have to watch out for when solving inequalities.
When you divide both sides of an inequality by a negative number, you must switch the direction of the inequality sign. So this less than in our original problem becomes greater than in our second step. I would recommend switching it as soon as possible so you don't forget.
Let's rewrite our original inequality.
-45 < -9k
On the right side, the -9's cancel and we're left with <em>k</em> and on the right side, -45 divided -9 is -5. So we have <em>5 </em><em>></em><em> k</em>.
Answer:
n=-6
Step-by-step explanation:
If 945 is the product of 5 CONSECUTIVE ODD numbers, let's find the prime factors of 945:
945 = 5 x 7 x 27 , but we need 5 odd numbers:
945= 5 x 7 x ( 3 x 9 ) we still need one factor. This factor cannot be but 1
945 = 1 x 3 x 5 x 7 x 9 = 945 and the greatest value of these integers is 9
