Answer:
-x + -13
Step-by-step explanation:
Rewrite: 5(x – 4) + 3x – 9x + 7
Step 1: 5(x + –4) + 3x + –9x + 7
Step 2: 5x + -20 + 3x + –9x + 7
Step 3: 5x + 3x + –9x + -20 + 7
Step 4: -1x + -13
Step 5: -x + -13
The change in the stock market from the beginning of the day to the end of the day is 29 3/4
<h3>How to determine the change in the stock market from the beginning of the day to the end of the day?</h3>
The given parameters are:
Beginning = 60 3/4
End = 90 1/2
The change in the stock market from the beginning of the day to the end of the day is calculated as;
Change = End - Beginning
So, we have
Change = 90 1/2 - 60 3/4
Evaluate
Change = 29 3/4
Hence, the change in the stock market from the beginning of the day to the end of the day is 29 3/4

we are given
62% of the students take math
so,
49% take science
38% take both science and math
n(M∩S)=38
now, we can use union formula
n(M∪S)=n(M)+n(S) -n(M∩S)
now, we can plug values
and we get
n(M∪S)=62+49 -38
n(M∪S)=73
so,
the percentage takes at least one science or math course is 73%..........Answer
