Answer:
The value of x are all real number on x-axis the number that falls under x
example of the value of x are in this equation
y=2+5x
2x+6y=60
to find x
let make the first one equation 1 and the second equation 2
now, put equation 1 in equation 2
2x+6(2+5x)=92
open the by multiplying every thing in the bracket by 6
2x+12+30x=92
combine the like terms
2x+30x=69212
32x=80
now divide via by 32
32x/32=80/32
x=5/2
80 weeks
1,200+40x=400+50x
800+40x=50x
800=10x
x=80
Answer:
one quarter of the total number of students will be those who failed their exam.
Step-by-step explanation:
Three - fourths = those who passed the exam
one quarter will be those who failed their exam
From the total number of the students.
Let's make an example
40 students who take the exam.
3 over 4 students from the total number of 40 take the exam and the result is passed and it mean 30 students passed in the exam.
1 over 4 students take the exam and the result is failed and it mean 10 students failed in the exam.
4 minus 3 over 4 will get the answer 1 over 4.
Use 1 over 4 to multiple with the total number of the students and that how you will get the answer for those who failed in their exam.
