Paul is 6 times as old as his brother. Paul is 12 years old. How old is his brother? Show work ​

2

Step-by-step explanation:

12/6

2 years

Step by step explanation:

Let Paul's brother's age be x years.

Paul is 6 times as old as hus brother so, his age will be 6x.

According to question, Paul's age is 12 years so,

6x=12

or, x=12/6

or, x=2

Hence, his brother is 2 years old.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
