Alight year is defined as the distance light travels in one year. one light year is 9.46 x 10^12 kilometers. a galaxy is about 150.000 light years wide. about how many kilometers wide is the galaxy?

1.419E15

Step-by-step explanation:

first you have to multiply 9.46*10^12=9460000000000

then you have to multiply 9460000000000*150.000= 1.419E15

Hope I helped :)

but which class are u may know that first

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
