The given expression is:
So, there are two terms in the expression
1)
2) -5
The constant term is -5.
The co-efficient of
is 4.
It is always important to go through the given problem first to get a concept of the requiremement. Then all the information's available from the question has to be noted down in such a manner that there would be no need to look at the question while solving.
Total number of students wearing jeans = 10
Total number of students wearing shorts = 9
Total number of students wearing capris = 2
Then the total number of students surveyed by Mrs Lane = (10 + 9 + 2)
= 21
Now percentage of students wearing shorts = (9/21) * 100
= (3/7) * 100
= 300/7
= 42.85 percent
So a total percentage of 42.85% of the students were wearing shorts.
1/4 to a decimal 0.25
to a percent is 25%
Use the distributive property backwards.
xp+yp=z become p(x+y)=x, which solves to p=x/(x+y)
