Steps to solve:

-5(x - 2) = -(x + 6)

~Simplify both sides

-5x + 10 = -x - 6

~Subtract 10 to both sides

-5x = -x - 16

~Add x to both sides

-4x = -16

~Divide -4 to both sides

x = 4

Best Of Luck!

Answer:

\huge{ \bold{ \huge{ \boxed{ \sf{x = 4}}}}}

Step-by-step explanation:

\sf{ - 5(x - 2) =  - (x + 6)}

Distribute -5 through the parentheses in left hand side

Similarly, distribute ( - ) sign through the parentheses in right hand side

\longrightarrow{ \sf{ - 5x + 10 =  - x  - 6}}

Move x to left hand hand side and change it's sign

Similarly, move 10 to right hand side and change it's sign

\longrightarrow{ \sf{ - 5x + x =  - 6 - 10}}

Collect like terms

\longrightarrow{ \sf{ - 4x =  - 6 - 10}}

The negative integers are always added but posses the negative ( - ) sign

\longrightarrow{ \sf{ - 4x =  - 16}}

Divide both sides by -4

\longrightarrow{ \sf{ \frac{ - 4x}{ - 4}  =  \frac{ - 16}{ - 4}}}

Calculate

\longrightarrow{ \sf{x = 4}}

Hope I helped!

Best regards! :D

Ardi and Lei are both travelling by train. Ardi's train travels 70 km in 35 minutes. Lei's train travels 585 km. It leaves at 9:
Leni [432]

Answer:

10 km/hr

Step-by-step explanation:

Average speed = Total distance travelled / Total time taken

Ardi:

Total distance travelled = 70 km

Total time taken = 35 minutes = 35/60 hour

Average speed = Total distance travelled / Total time taken

= 70 km ÷ 35/60 hr

= 70 × 60/35

= 4,200/35

= 120 km/hr

Lei:

Total distance travelled = 585 km Total time taken = 9:05 - 13:35 = 4 hours 30 minutes

= 4.5 hours

Average speed = Total distance travelled / Total time taken

= 585 km / 4.5 hours

= 130 km/hr

Difference, in km/h, between the average speed of their trains = Lei's train - Ardi's train

= 130 km/hr - 120 km/hr

= 10 km/hr
