Answer:
No solution
Step-by-step explanation:
-5r + 6 ≤ -5( r+2 )
-5r + 6 ≤ -5r -10
6 ≤ -10
Answer:
m = 50
Step-by-step explanation:
∠ D and ∠ A are vertically opposite angles and are congruent , then
m - 130 = 20 - 2m ( add 2m to both sides )
3m - 130 = 20 ( add 130 to both sides )
3m = 150 ( divide both sides by 3 )
m = 50
