Answer:
535 students passed and 107 students failed
Step-by-step explanation:
Create a system of equations where p is the number of students who passed and f is the number of students who failed:
p + f = 642
p = 5f
Solve by substitution by plugging in 5f as p into the first equation, then solving for f:
p + f = 642
5f + f = 642
6f = 642
f = 107
So, 107 students failed.
Find how many students passed by multiplying this by 5:
107(5)
= 535
535 students passed and 107 students failed.
Answer:
Option D is correct
The point slope intercept equation of line =
Step-by-step explanation:
Given: The slope of line (m) = 2 and also it is given from the figure the
Point-slope intercept form: If we have a point and a slope, m, then the formula
we use to find the equation of a line:
.......[1]
Substitute the value of m =2 and (1, 9) in [1];
Therefore, the point slope intercept equation of the line is:
Answer:
Step-by-step explanation:
GCF = Greatest common factor.
For example: 6 is the GCF of 12 and 18.
The given expression:
It can be written as
Taking out common factor , we get
Hence,
<span>let x be number of bicycles
and y the number of</span> tricycles<span>
So
x + y = 25 equation 1
The number of wheels is
2x + 3y = 63 equation 2
</span>We can multiply the equation 1 by two and subtract from the second one...
2x + 3y = 63
-(2x + 2y = 50)
then
y = 13 trikes and
x = 12 bikes
