B. (F+g)(x)=5+9x
C. (F+g)(x)=15+5x
D. (F+g)(x)=15+9x
Answer:
C
Step-by-step explanation:
To find the sum of f and g then add the expressions f(x) and g(x).
f(x) + g(x)
10-2x + 7x+5
10+5x+5
15+5x
This means that (F+g)(x) = 15+5x.
You can spot the pattern (if you are going from right to left) is division by 2.
if you divide 1 by two it is 0.5
if you divide 0.5 by two it is 0.25
answer: 0.5,0.25
Answer:
The total number of students that voted in the election is 308
Step-by-step explanation:
Given
Number of Students: 350
Percentage of Students that votes: 88%
Required
Number of students that voted.
To calculate the number of students that voted in the election, we have to multiply the percentage given by the total number of students in the school.
This is so because the percentage represents those that voted.
Mathematically, this is represented as:
Number of students that voted = Percentage of students that voted * Total number of students
By substitution, we have
Number of students that voted = 88% * 350
(Convert the percentage to fraction)
Number of students that voted =
(Multiply Numerators)
Number of students that voted =
Number of students that voted =
Number of students that voted =
Hence, the total number of students that voted in the election is 308
Here is how you would do this: If there are 1000 meters in one kilometer, and you know that this track is 200 meters long, then you can find how many times Julius must run around the track in order to reach ONE kilometer:
1000 meters / 200 meters = 5 times in around the track for ONE kilometer.
To find how many times Julius would need to run around to reach THREE kilometers you simply do the following:
5 x 3 = 15 ---> Julius would need to run around the track 15 times in order to reach 3 kilometers.
