I NEED HeLp THESE QUESTIONS MEAN ALOT THEY DECIDE ID iF I FAIL OR paSS

1. The hiker's elevation after 6 minutes was 30 feet!

E- Each minute for 6 minutes, 10*60 is 60, -30+60 is equal to 30!

2. Taylor answered 9 questions incorrectly.

E-If you do, 0.8*45, the answer is 36, which means Taylor answered 36 questions CORRECTLY. 45-36 is 9.

3. Lauren will bike 20 miles in one hour.

E- 1 hour=8/8 hours. 2*8 is 16. 1/2 times 8 is 4. 16+4=20!  You can also do 2 1/2= 2.5. 2.5*8 which is 20.

4. 13 full rows

E- 2/3 of 20, or 2/3*20 is 13 1/3. Since it asks for full rows, they filled 13 rows.

5. 1 1/4.

E- Just add it.

6. Selling price is $20.4

E- 12*0.7 is 8.4. So since they mark UP, add 8.4 to 12, and you get 20.4.

7. 5x-1

E- Look at screenshot.

8. Option 4/D or 0.63 (repetition bar over the 3)

E-Just divide and you get the answer 0.63 (etc)

9.  12 equal pieces are created.c

E- Divide 3/4 by 1/16 and you get 12.

10. 6x+2 is the perimeter

E- I don't know how to explain, just solve!

11. 76.62 was the original price.

E- 0.3*58.94 is 17.68. Since the sneakers WERE marked down that much, add that to the new amount. 58.94+17.68 is 76.62.

Brainliest please!

12. -0.7

E- Let's convert both to fractions, 105% in terms of 20s is 21/20. 21/20-35/20 is -14/20. Convert that to a decimal and you get -0.7
