Answer:
D
Step-by-step explanation:
Note there is a common difference d between consecutive terms in the sequence, that is
d = 2 - 5 = - 1 - 2 = - 4 - (- 1) = - 3
This indicates that the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = - 3, thus
= 5 - 3(39) = 5 - 117 = - 112 → D
Answer:
2d = 2x + 5b = 6p
Step-by-step explanation:
2d = 1x + 5b + 1x = 6p
2d = 2x + 5b = 6p

Add all of them together
Step-by-step explanation:
1200m + 170m + 20m + 120m = 1,510m
Answer:
(100/t) minutes
Step-by-step explanation:
Craig's rate can be written as (5 minutes/t pages). This is a conversion factor. This means we can also invert the factor to (t pages/5 minutes), if desired. A conversion factor tells us the that top value is equal to the bottom value, such as 12 inches/1 foot. This can be inverted to 1 foot/12 inches.
We want to know how many minutes Craig needs to type 20 pages. Assuming no distractions, we can use the conversion factor.
We can write: (20 pages)*(5 minutes/t pages)
(20 pages)*(5 minutes/t pages)
(20 )*(5 minutes/t ) [The pages unit cancels]
(100/t) minutes
====
We don't know the value of t, so the result must include t. If t happens to be 2 pages, for example, it would take Craig (100/2) or 50 minutes, to type 20 pages.
