let there are x number of trees
Justus samples 3 oranges from one tree
Number of oranges he samples from x trees =3x
Extra oranges =50
total number of oranges = 3x+50
as a function f(x) we can write it as
f(x) =3x+50
Answer:
50 degrees.
Step-by-step explanation:
Angle FGE = 
because angles on a straight line add up to 180 degrees.
Angle EFG = 
(Angles in a triangle add up to 180)
Add 20 to both sides:
Subtract 6x from both sides:
Angle 
Answer:
9a + 6b and 5c - 3d
Step-by-step explanation:
(a)
4a + 7b + 5a - b ← collect like terms
= (4a + 5a) + (7b - b)
= 9a + 6b
(b)
6c + 4d - c - 7d ← collect like terms
= (6c - c) + (4d - 7d)
= 5c - 3d
