4 2/7 equals 30/7
30/7 divided by 9 equals 10/21
So the crew built 10/21 of a km everyday
The simplification of the expression is 28. The mistake in your calculation occurred in step 3.
<h3>What is the process involved in simplifying expression involving brackets?</h3>
TO simplify expressions involving brackets, we use a common method called BODMAS (Brackets, Of, Division, Multiplication, Addition, and Subtraction).
This means that we will first solve the expression in brackets first, followed by division, multiplication, addition, and subtraction as the case may be.
Now, from the given information, we have:
= 22+6[(14-5)÷3(17-14)]
solving parameters in the bracket first, we have:
= 22 + 6[(9) ÷3(3)]
= 22 + 6[(9) ÷9]
- The above step is where you missed it from your calculation, you must first open all brackets within brackets before solving them.
= 22 + 6[(9) ÷9]
= 22 + 6[ 1]
= 22 + 6
= 28

Answer:
f(x) = x² + 5 / x - 5
There is infinite discontinuity at x = 5. At this value, the graph becomes undefined because the denominator is 0.
Answer:
D) 1000
Step-by-step explanation:
<u><em>The options of the question are</em></u>
A) -1000 B) -7 C) 7 D) 1000
we know that
The sea level is the reference value to represent elevation, and it is considered as zero level.
Above sea level is considered positive and below the sea level is considered negative
we have
New Orleans is 7 feet below sea level
so
New Orleans elevation is -7 ft
Oklahoma is 1000 feet above the sea level
so
Oklahoma elevation is +1000 ft
therefore
Oklahoma City's elevation is represented by 1000
