<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.
Multiply each term in parenthesis by the number outside the parenthesis: (7*x) + (7*7)
Hope this helps you
To solve this, you will have to set up your equation as fractions:
X is to 4 as 4 is to 4+3, or 7
X/4 = 4/7
You will then cross multiply
7x = 4•4
7x = 16
Divide.
X = 2.285714...
Round to the nearest hundredth.

Answer:
Average rate of change for given function is: -2
Step-by-step explanation:
Given function is:
In order to find the rate of change, we have to find the value of function on x1 and x2
So,
The formula for finding the rate of change is:
Putting the values, we get
Hence,
Average rate of change for given function is: -2
Answer:
a. 5
b. 545
c. 0
Step-by-step explanation:
These are straightforward division problems, easily solved using your own memorized multiplication facts, or using a calculator.
a. 20 ÷ 4 = 5 means 5 × 4 = 20
b. 2725 ÷ 5 = 545 means 545 × 5 = 2725
c. 0 ÷ 5 = 0 means 0 × 5 = 0
