Answer:
x≥−4
Step-by-step explanation:
Add x to both sides.
2x+7+x≥−x−5+x
3x+7≥−5
Subtract 7 from both sides.
3x+7−7≥−5−7
3x≥−12
Divide both sides by 3
x≥−4

Answer:
3) The number of apples at the start
Answer:
2 hours
Step-by-step explanation:
Each hour, Sam earns $9
So 2 hours, Sam will earn 2 * $9 = $18
Thus, Sam will earn $18 in 2 hours working at the drugstore.
a) Here, sum of two non-adjacent angles: 52 + 25 = 77
Now, ∠3 = 180 - 77 [ sum of all angles in a triangle is 180 ]
so, ∠3 = 103
Now, ∠3 + ∠4 = 180 [ Supplementary angles ]
So, ∠4 = 180 - ∠3
∠4 = 180 - 103 = 77
∠4 = 77 [ which is sum of two non-adjacent angles ]
....Hence proved.
b) m∠4 = 77
[ Solved in previous section ]
Hope this helps!
