Answer:
250%
Step-by-step explanation:
2 1/2 = 2 wholes and 1/2 of another
100% = 1 whole
<span>When we remove those parentheses, the sign of every term
within the parentheses changes.</span>
Problem 2. Remove the parentheses.
a) p + (q −r + s) <span>= p + q − r + s</span>
b) p − (q −r + s) <span>= p − q + r − s</span>
In each of the following problems, remove the parentheses, then simplify
by adding the numbers.
For example,
<span><span><span>(x − 3) − (y − 4)</span> = <span>x − 3 − y + 4</span></span> <span> = <span>x − y + 1.</span></span></span>
The sign preceding (x − 3) is understood to be + . Therefore the signs within those parentheses do not change.
But the sign preceding (y − 4) is minus. Therefore, y changes to −y, and −4 changes to +4.
Finally, it is the style in algebra to to write the literal terms, x − y, to the left of the numerical term.
Answer: m=-1
Step-by-step explanation:
Whenever a question says "<u>solve</u>" it means that you have to find the constant (m in this case).
You do this by rearranging the equation so that in one side is the constant and the other side the numbers.
5m+4=7m+6 becomes: 5m-7m=6-4
Then: -2m=2
: m=-2/2
: m=-1
