Answer:

Step-by-step explanation:
given
45 = 25m + b ( isolate the term in m by subtracting b from both sides )
45 - b = 25m ← divide both sides by 25
= m

Answer:
= 6n - 3
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 9 - 3 = 15 - 9 = 21 - 15 = 6
This indicates 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 = 3 and d = 6, then
= 3 + 6(n - 1) = 3 + 6n - 6 = 6n - 3
Answer:
C. 1/12
Step-by-step explanation:
The scale can be calculated by comparing side lenghts
AC is similar to FD and AB is similar to FE and BC is similar to ED
AB = 2 and FE = 24 so AB/FE is = 2/24 that's simplified is 1/12
