Answer:
z = 20
Step-by-step explanation:
subtract 19z from 20z, and add 8 to 12. you will be left with 20 = 1z. Divide 1 by 20 and you will have Xz =20.

In the given problem, the
numerical value of 805, which is in the tens place, we can first elaborate and
clearly specify the order of numbers by using the expanded form:
<span><span>1. </span><span> 800 = eight
hundred / hundreds</span></span>
<span><span>2. </span><span> 0 = zero / tens</span></span>
<span><span>3. </span><span> 5 = five / ones
</span></span>
Conclusively the tens value of
the number is zero or none, since zero is not a real number then it can’t be
considered but nevertheless, the value is 0 expressed with respect to the whole
numbers.
        
             
        
        
        
Answer:
g(n) = 2n + 49
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
g(n) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given the recursive formula
g(n) = g(n - 1) + 2 ← with d = 2 and a₁ = 51, then
g(n) = 51 + 2(n - 1) = 51 + 2n - 2 = 2n + 49 ← explicit formula
