Answer:
Step-by-step explanation:
If you want to find out how many times larger something is than something else, you have to divide. We will set up a problem that looks like this:

Diving 2.1 by 4.2 gives us .5; to divide the exponents, we remember that if we divide like bases we have to subtract the exponents. 10 is our base in both cases, so 8 - 2 gives us 6, resulting in:

However, this isn't in scientific notation. We need to move the decimal one more place to the right, which in trn reduces the exponent by 1:

X=13+4x. 13+4x=22
0=13+3x. 4x=9
3x=-13. x=9/4
x=13/3
Answer:
-1/2

Arithmetic Sequence
The value of the 93th term of this arithmetic series is -925
Step-by-step explanation:
The first term of the arithmetic term is a = -5
And the common difference is d = a2-a1 = -15 - ( - 5) = -10
So the 93th term if this arithmetic progression is given by
an = a + (n-1) × d
where an is the nth term of the arithmetic progression
so in order to calculate the 93rd term (a93), the value of n = 93
so a93 = -5 + (93-1) × (-10)
a93 = -5 + (-920
)
a93 = -925
Hence the value of the 93th term of this arithmetic series is -925
