This an Arithmetic Progression question: (odd number: 1,3,5,7,...)
1st term a₁ = 1
the common difference is d=2
a term of rank n in a AP = a₁ + (n-1)d, where n = rank of the term.
Now let's apply the formula
a₈₇ = a₁ + (87-1).2
a₈₇ = 173
I believe they just want you to add here, so for:
a. 12,419,293+100,000
b. 12,419,293+1,000,000
c. 12,419,293- 10,000
the increase is addition and decrease is subtraction. If you're having trouble adding and subtracting them put them over each other and subtract or add them like:
12,419,293
+ 1,000,000
-------------------
The equation is x-6=30 and you got your answer.
Answer:
B)
Step-by-step explanation:
∠4 and ∠2 are vertical angles as well, but since they are already used, all that are left to use are ∠3 and ∠1, which are the other vertical angles.

Answer:
$10.80
Step-by-step explanation:
