Answer:

-4d

Step-by-step explanation:

We can subtract a term from another if they have the same variable. Both 3d and 7d have the variable d, so we can subtract them.

When subtracting these terms, we subtract the coefficients and keep the variable.

So:

3d - 7d = 3-7(d) = -4d

Hope this helped!

Answer: 1. 2rs is 2 . r . s = 2rs                                                                                               2. 18rst is 2 . 3 . 3 r. s. t = 18rst

3.  25ab is 5 . 5 a . b  = 25ab                                                                                   4. 30abc is 2 . 3 . 5 a . b . c= 30abc                                                                                          5. 45abr is 3 . 3 . 5 . a . b . r

Step-by-step explanation: 2. 18rst is 2 . 3 . 3 . r . s . t because 2 x 3 = 6 x 3 = 18rst.    

3. 25ab is 5 . 5 a . b because 5 x 5 = 25ab

4. 30abc is 2 . 3 . 5 a . b because 2 x 3 = 6 x 5 = 30abc.

5. 45abr is 3 . 3 . 5 . a . b . r because 3 x 3 = 9 x 5 = 45abr.

Hope this works! :) If not, I am sorry :(.  If it does, Your Welcome! :)

Element X decays radioactively with a half life of 9 minutes. If there are 890 grams of Element X, how long, to the nearest tent
elena-s [515]

Answer:

13.18651685

13.9

Explain:

890-238=652
652/890=0.7325842697 (Find out the percentage)

We know that 1 gram of Element X will be fully decayed in 18 minutes and half of it in 9 minutes.

0.7325842697x18=13.18651685

As you see 18/13.18651685 will equal to 18 (not exactly since it is rounded)

And of course we need to round it to nearest tenth. So the answer would be 13.9!
