Answer:
a. One solution
Step-by-step explanation:
These are two linear equations with different x-coefficients. They have one solution.
__
<em>Additional comment</em>
If the x-coefficients are the same, the system may have 0 or infinite solutions, depending on the constants. It is not possible for a system of linear equations to have exactly two solutions.
Answer:
x=7
Step-by-step explanation:
7x-7=4x+14
3x=21
x=7
Answer:
m
Step-by-step explanation:
Given parameters:
Length of rope = 11m
First length cut off = 
m
Second length cut off = 
m
Unknown:
Remaining length = ?
Solution:
Let us find the total length cut off first;
= m + m
= 
= 
m
So,
Remaining length = 11 -
= 
= m
Answer:
Step-by-step explanation:
Sum of exterior angles of regular polygons is 360°.
If each angle measures 15°, then the number of sides:
- 15n = 360
- n = 360/15
- n = 24
