Given:
The statement is given as 5 subtracted from w is less than or equal to 16.
The objective is to write inequality for the given statement.
Explanation:
Consider the first statement that is 5 is subtracted from <em>w</em>.
Then, the equation can be written as,
Explanation:
The result should be less than or equal to 16.
Thus, the final equation can be written as,
Hence, the obtained inequality is w - 5 ≤ 16.
I think the right answer is A
<span>If you would like to
know how many of each did Jan buy, you can calculate this
using the following two equations:
b ... the number of books
m ... the number of magazines
$16 = b * $3 + m * $2.50 ... 16 = 3 * b + 2.50 * m
b + m = 6 ... b = 6 - m
__________________
</span>16 = 3 * b + 2.50 * m
<span>16 = 3 * (6 - m) + 2.50 * m</span>
16 = 3 * 6 - 3 * m + 2.50 * m
16 - 18 = - 3 * m + 2.50 * m
- 2 = - 0.50 * m /0.50
m = 2 / 0.50
m = 4 magazines
<span>b = 6 - m = 6 - 4 = 2 books</span>
Result: Jan bought 4 magazines and 2 books.
Both expressions equal 5 when substituting 2 for x because the expressions are equivalent. Hope this helped :D
Since it is positive power, the answer is -1 so it is B.
