Someone plz the table shows different geologic time periods: period number of years ago jurassic 2.08 ⋅ 10^8 silurian 4.38 ⋅ 10^8 tertiary 6.64 ⋅ 10^7 triassic 2.45 ⋅ 10^8 order the time periods from oldest to youngest. a. tertiary, jurassic, triassic, silurian b. jurassic, triassic, silurian, tertiary c. silurian, triassic, jurassic, tertiary d. triassic, silurian, jurassic, tertiary

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
