Answer:
x = -4/5
Step-by-step explanation:
(5x - 2)2 = 10
2(5x - 2) = 10
2 * 5x = 10x
2 * -2 = -4
5x - 4 = 10x
+4 +4
5x = 10x + 4
-10x -10x
-5x = 4

Answer:
40 and 1/2
Step-by-step explanation:
Multiply 4 1/2 by 1 1/2. Then multiply the product of 4 1/2 and 1 1/2 by 6.
So,
Simply divide 12 by 18.
The experimental probability of tossing heads was 2 out of 3.
Answer:
Step-by-step explanation:
Lines m and l are the parallel lines and a line 'n' is a transverse intersecting these lines.
m∠2 = 50°
m∠1 + m∠2 = 180° [Linear pair of angles]
m∠1 = 180° - 50°
m∠1 = 130°
m∠3 = m∠1 = 130° [Vertically opposite angles]
m∠3 + m∠5 = 180° [Consecutive interior angles]
m∠5 = 180° - m∠3
= 180° - 130°
= 50°
m∠6 + m∠5 = 180° [Linear pair of angles]
m∠6 = 180° - 50° = 130°
