Answer:
=> x° + 57° + (43°+24°) = 180° ------------ (angle sum property of ∆)
=> x° + 57° + 67° = 180°
=> x° + 124° = 180°
=> x° = 180° — 124°

Answer:
x < -3
Step-by-step explanation:
Isolate the x. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 6 from both sides.
4x + 6 (-6) < -6 (-6)
4x < -6 - 6
4x < -12
Next, divide 4 from both sides.
(4x)/4 < (-12)/4
x < -12/4
x < -3
x < -3 is your answer.

Answer: y = 6 x = 0.2
Step-by-step explanation:
5x+y=7
20x+2=y
re-write one
5x + y = 7 OR y = 7 - 5x
substitution
20x + 2 = 7 - 5x
20x + 5x = 7 - 2
25 x = 5
x = 5/25
x = 0.2
now for finding y
y = 7 - 5x
y = 7 - 5(0.2)
y = 7 - 1
y = 6
