Answer:
The ratio is 5:4 and the only one that fits is 25,20 so that's the answer.
Step-by-step explanation:
Answer: c
This system has infinitely many solutions.
Step-by-step explanation:
Solve by substitution:
1) Solve for :
2) Substitute for in :
3) Simplify both sides of the equation:
Therefore, This system has infinitely many solutions.
Solve by elimination:
You can't solve this system of equations by elimination.
Solve by graphing:
The lines are directly on top of each other, Therefore there are infinitely many solutions.
Answer:
You can use a number line to find it out.
Step-by-step explanation:
Answer: ∡RSQ and ∡TSQ
Supplementary angles are angles that add up to 180 degrees. We can see in the picture that both angles are located on the same line, and no other angles are involved, so they must equal 180.
We can also use the process of elimination:
- ∡RSQ and ∡UVS are congruent because they are consecutive angles.
- ∡RSQ and ∡WVX are also congruent because they are alternate exterior angles.
- ∡RSQ and ∡TSV are also congruent because they are vertical angles.
