Solve the Answer for x.<br> 56 &lt; 7(7-x)
Ierofanga [76]

Answer:

x < -1

Step-by-step explanation:

<u>Step 1:  Distribute</u>

<u />56 < 7(7 - x)

56 < (7 * 7) + (7 * -x)

56 < 49 - 7x

<u>Step 2:  Subtract 49 from both sides</u>

<u />56 - 49 < 49 - 7x- 49

7 < -7x

<u>Step 3:  Divide both sides by -7</u>

<u />7 / -7 < -7x / -7

Since you divided by a negative, you must flip the sign.

<u />7 / -7 < -7x / -7

-1 > x

Answer:  x < -1

Find <br> 6<br> 2<br> (<br> 9<br> )<br> . Express your answer as a fraction in simplest form.
kotykmax [81]

Based on the expression given, when it is solved, as a fraction in its simplest form it would be 558/1.

<h3>What is the fraction in its simplest form?</h3>

The expression, 62(9) can be rewritten as:

= 62 x 9

This is because the brackets denote that the number within the brackets should be multiplied by the number outside the bracket.

The solution is:

= 62 x 9

= 558

As this is an integer, it means that it has a denominator of 1. The fraction in its simplest form is therefore:

= 558 / 1
