For more information on how to solve a system of equations in two to three variables, watch the above You-Tube link and subscribe to my channel [USERNAME: MATHEMATICS WIZARD], and as always, I am joyous to assist anyone at any time.
The first thing we must do for this case is to define variables:
x: dimes
y: quarters
We now write the system of equations.
We have then:
x + y = 22
0.10x + 0.25y = 3.70
Solving the system of equations we have:
x = 12
y = 10
Answer:
He has:
12 dimes
10 quarters
Answer:
x⁵
Step-by-step explanation:
If 4 points are non-coplanar, then they are non-collinear....true
if 4 points are non-collinear, then they are non-coplanar...false
counter example : 4 points may be non-collinear and yet lie in the same plane.
Just you need to multiply both variables
- Multiply 5 and 9 we will get our required solution
