<span>The sum of 324, 435, and 546 is 1305. If this number were to be expressed by the base of 7, we would need to figure out what value of exponent would satisfy the requirement. This can be done by setting up an equation where 7 to the power of x must equal 1305. Using logarithms, one can solve for x and find it to be 3.6866853. Thus the sum of the aforementioned numbers, expressed in by the base of 7, is 7^3.6866853.</span>
13 lbs shared between 3 batches . . .

The error is in step 4. The sign was not changed after dividing both sides by -10. Thus, the answer to the inequality should be: -27/10 ≥ x.
<h3>How Negative Number Changes Inequality Sign?</h3>
When we divide or multiply two sides of an inequality by a negative number, the inequality sign is changed to the opposite, i.e. from < to > or from > to <.
In step 4, the sign was not changed after dividing both sides by -10.
The answer should be, -27/10 ≥ x.
