Since it is given that the reduction in the amount of waste each week is linear, it is conclusive that these data are also in arithmetic sequence. First, determine the common difference (d)
d = (a10 - a5) / (10 - 5)
Subsituting the known values,
d = (30 - 40) / 5 = -2
To determine any term (at) of the arithmetic sequence,
at = a1 + (n - 1) x d
Solve for a1 by using either the given a5 or a10,
40 = a1 + (5 -1) x -2 ; a1 = 48
The equation becomes,
at = 48 + -2(n -1)
Answer:
Step-by-step explanation:
Find x
- 8/10 = 5/(5 + x) Cross multiply
- 8*(5 + x) = 10*5 Combine on the right
- 8(5 + x) = 50 Remove the brackets on the left.
- 40 + 8x = 50 Subtract 40 from both sides.
- 40-40 +8x = 50-40 Combine
- 8x = 10 Divide by 8
- 8x/8 = 10/8 Divide
- x = 1.25
Find y
- 7/(7 + y) = 8/10 Cross multiply
- 8*(7 + y) = 10 * 7 Combine the right
- 8(7 + y) = 70 Remove the brackets.
- 56 + 8y = 70 Subtract 56 from both sides
- 56 - 56 + 8y = 70 - 56 Combine
- 8y = 14 Divide by 8
- y = 1.75
