If we let the score of team tackle as x, then the score of team sack x - 7. Their combined scores totaled 83, in equation form, that is:
x + x - 7 = 83
Solving for x
2x = 83 + 7
2x = 90
x = 45
x - 7 = 38
The two scores are 45 and 38.<span />
Answer:
80,543 employees total
Step-by-step explanation:
22.1% of total = 17,800 employees
0.221 of x = 17800
0.221 • x = 17800
x = 17800 / 0.221
x = 80542.98643
x ≈ 80543 employees total
9514 1404 393
Answer:
(b) a[1] = -7, a[n] = a[n-1] + 3
Step-by-step explanation:
Comparing the given formula to the general form for the n-th term of an arithmetic sequence ...
an = a1 +d(n -1)
we see that the first term (a1) is -7, and the common difference (d) is +3.
The recursive version of the sequence definition is ...
a[1] = a1
a[n] = a[n-1] +d
So, the appropriate choice is ...
a[1] = -7, a[n] = a[n-1] +3
