Answer: 246 students
step by step explanation:
1. 50% of 1,640 is 820 students come by bus
2. 35% of 1,640 is 574 students come by car
3. Add 820 and 574 together to get 1,394
4. Subtract 1,394 from 1,640 which will give you 246 student who walk to school
Answer:
x=15
Step-by-step explanation:
Since we know that f(x) = -x+5 and f(x)= -10 we can say that -x+5 = -10. When we simplify this, we get that -x=-15 which equals to x=15.
For no solutions, put a = b = c = -1, for exactly one solution, put a = 1 and b = c = 0 and for infinite solutions, put a = b = c = 5 in the system of linear equations.
We have the system of equations:
x + y + z = 2 …(1)
a x + b y + c z = 10 …(2)
x - 2 y + z = 4 …(3)
a. The system has no solution.
Put a = b = c = -1 in (2)
We get:
- x - y - z = 10
Now add (1) and (2)
0 = 12
which is not possible.
So, no solution.
b. The system has exactly one solution.
a = 1 and b = c = 0
We have the equations as:
x + y + z = 2 …(1)
x = 10 …(2)
x - 2 y + z = 4 …(3)
c. The system has infinitely many solutions.
a = b = c = 5
We will have the equations:
x + y + z = 2 …(1)
5 x + 5 y + 5 z = 10 …(2)
x - 2 y + z = 4 …(3)
Therefore, we get that, for no solutions, put a = b = c = -1, for exactly one solution, put a = 1 and b = c = 0 and for infinite solutions, put a = b = c = 5 in the system of linear equations.

A rectangular prism has a length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm. A similar prism has a length of 14.7 cm, a width of 20.3 cm, and a height of 33.6 cm.
The dimensions of the smaller prism are each multiplied by what factor to produce the corresponding dimensions of the larger prism?
