Good Morning

a-3b=16

a=b-2

Solve a=b -2 for a

Substitute b-2 for a in a-3b=16

a-3b=16

b-2-3b=16

Simplify both sides of the equation

-2b-2=16

Add 2 to both sides

-2b-2+2=16+2

-2b=18

Divide both sides by -2

-2b/-2 = 18/-2

b= -9

Substitute -9 for b in a=b -2

a=b -2

a=-9-2

Simplify both sides of the equation

a= -11

Answer: (-11,-9)


I hope that's help !

Which is one one way to check 102 ÷ 6 = <br>17
sleet_krkn [62]

One way to check if 102 ÷ 6 = 17 is by focusing on the left side of the equation.


102 ÷ 6 can be converted into \frac{102}{6}


\frac{102}{6} can be simplified, lets start by dividing the numerator and denominator by 2.

\frac{102/2}{6/2} = \frac{51}{3}

\frac{51/3}{3/3} = \frac{17}{1}

\frac{17}{1} can be rewritten as 17.

Light travels about 180 million kilometers in 10 minutes. How far does it travel in 1 minute ? How far does it travel in 1 secon
daser333 [38]

Answer:18 million and 300000

Step-by-step explanation:

Since light travels 180 million KM in 10 min, it would travel 180 million/10 in one minute. Thus, we get 18 million. As we know, there are 60 seconds in a min. Thus, there are 60*10=600 seconds in 10 minutes. Thus, 180 million/600 gives 300000
