Answer:
x=18
Step-by-step explanation:
<u>Key skills needed: Arithmetic Sequences, Addition</u>
1) We have a sequence of 8,13,x
2) To find the number being added every time, we do 13-8. This is 5.
3) This means x would be 13+5
4) 13+5 is 18 so x is 18.

Answer C. 2.00 Meters/second
1 kilometer = 1000 meter
1 hour = 3600 seconds
7.2 x 1000 = 7200
so 7200 meters an hour
or 7200 meters every 3600 seconds
7200/3600
we then want the 3600 to become one second to find meters per (1)second.
so 7200/3600 simplified = 2. 2 meters per second
answer C
The answer is 22 minutes:
20x for Tatsu and 10x for Andy
30x = 11
x = 11/30
11/30 * 60 = 22
"<span>5 to the negative 4th power over 5 to the 3rd</span>" translates to
5⁻⁴ / 5³
So you can just combine exponents.
5⁻⁴ / 5³ = 5⁻⁴ ⁻ ³ = 5⁻⁷ = 1/5⁷
Final answer: 1/5⁷
