You just need to substitute 20 for x and then solve.
a(20) = -5 +(20-1)3
Simplify: a(20) = -5 + (60-3)
Simplify: a(20) = -5 + 57
Result: a(20) = 52
So, 52 is the 20th term of the arithmetic sequence.

Answer below
Step-by-step explanation:
Large numbers like 100 billion are cumbersome to write out in ordinary form (100,000,000,000) and so scientists use a shorthand notation called powers of ten. ... The exponent tells you how many times ten is to be multiplied by iteslf to equal the number you wish to write. For example, 100 can be written as 10x10 = 102.
Hope this helps!

Answer:
9.33 Hours.
Step-by-step explanation:
The time in hours is given by the distance divided by velocity.
Now we are told that the velocity of the ship will be 25054 miles per hour, and the distance to the Moon is 233815 miles; therefore the time it will take the spacecraft to reach the moon will be:
Average of 93
4 scores
(95+92+89+x)/4<u>></u>93
times 4 both sides
276+x<u>></u>372
minus 276 both sides
x<u>></u>96
