The answer is

Answer:

x=22

Answer:

x = 22

Step-by-step explanation:

The 3 angles in a triangle sum to 180°

The third angle in the triangle forms a straight angle with 6x + 1

⇒ third angle = 180° - (6x + 1)° = 180 - 6x - 1 = 179 - 6x

Summing the 3 angles and equating to 180

179 - 6x + 79 + 2x + 10 = 180

- 4x + 268 = 180 ( subtract 268 from both sides )

- 4x = - 88 ( divide both sides by - 4 )

x = 22

So I need help pls show ur work
Ad libitum [116K]

Answer:

x = – ⅓

Step-by-step explanation:

The solution to the expression can be obtained as follow:

–3.1x + 7 – 7.4x = 1.5x – 6(x – 3/2)

Clear bracket

–3.1x + 7 – 7.4x = 1.5x – 6x + 9

–3.1x – 7.4x + 7 = –4.5x + 9

–10.5x + 7 = –4.5x + 9

Collect like terms

–10.5x + 4.5x = 9 – 7

–6x = 2

Divide both side by –6

x = 2 / –6

x = – ⅓

Thus, the solution to the equation is –⅓

Please help me with this , it would mean alot​
algol [13]

Answer:

Step-by-step explanation:

21-26. a = v - u / t

=> a = 47 - 19 / 5

=> a = 28 / 5

=> a = 5.6 m/s²

27-32. avg. speed = distance / time

=> 40 m / 10 s

=> 4 m/s

33-38. velocity = distance / time

=> v = 150 / 40

=> v = 15 / 4

=> v = 3.75 m/s
