Jenny is x years old. Thomas is 3 times as old as her. Jenny is 5 years older than Alexis. A) Find Alexis's age in terms of x
B) Find Thomas's age in terms of x.
C) If x=12, how much older is Thomas than Jenny?..

A) Alexis is x-5 years old

B) Thomas is 3x years old

C) Thomas is 24 years older than Jenny (3×12=36 ; 36-12)

Alexis is 7 years old Thomas is 36 years old Thomas is 24 years older than Jenny

step-by-step explanation:

divided 3/4 and 6

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.
