Volume= length times width times height
Answer:
i think the answer is 9.
Step-by-step explanation:
In 7th grade:
red-hair students =58
another color hair students =609
In 8th grade:
red-hair students =60
Let's assume
another color hair students =x
now, we are given
The numbers of red-haired students in 8th grade are proportional to the numbers in 7th
so,
now, we can solve for x
we get
we get
so, students have another color hair in 8th grade is 630.........Answer
Option A - (0,0) is a solution to both the equations. is the only true statement.
Step-by-step explanation:
Step 1 :
Given 2 equations are
n = m
n = 4m
Step 2:
(0,0) is a solution to both the equations.
This statement is true as substituting the point , the equations are true.
Step 3 :
Every solution to n=m is also a solution to n=4 m
Take the point (5,5)
This point lies on the equation n = m, as both the x and y co ordinates are same
n = 4 m = 4 × 5 = 20
So here for n = 5, n = 4 m is not true and hence this point is not a solution for the second equation thought it is a solution for the first equation
Hence this statement is not true
Step 4:
The graph of the solutions is parallel lines
this statement is not true because the 2 lines intersect at (0,0) as observed from step 2.
Step 5 :
No point on the line n=m is also a point on n=4 m
This statement is not true because (0,0) is a point on both the lines.
Step 6 :
Answer :
Option A - (0,0) is a solution to both the equations. is the only true statement.
