How do you solve the problem and what is the answer?<br><br>-2 = g -9<br>​
pogonyaev

Answer:

Hey Dude ok so it's g = 7 Have a nice day!

Step-by-step explanation:Simplifying

-2 = g + -9

Reorder the terms:

-2 = -9 + g

Solving

-2 = -9 + g

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '-1g' to each side of the equation.

-2 + -1g = -9 + g + -1g

Combine like terms: g + -1g = 0

-2 + -1g = -9 + 0

-2 + -1g = -9

Add '2' to each side of the equation.

-2 + 2 + -1g = -9 + 2

Combine like terms: -2 + 2 = 0

0 + -1g = -9 + 2

-1g = -9 + 2

Combine like terms: -9 + 2 = -7

-1g = -7

Divide each side by '-1'.

g = 7

Simplifying

g = 7

What is the speed of a car that traveled a<br> total of 300 kilometers north in 2 hours?
Vlad1618 [11]

Speed = Distance/Time

So, speed

= 300 km/2h

= 150km/h

= (150 × 1000m) / 3600s

= 150000m/3600s

= 41.66m/s [approximately]
