Subtract 2L from both sides
Subtract 9 then multiply by 4
Multiply by K
Subtract 2L from both sides
Subtract 9 then multiply by 4
if there are 26 students in each third-grade class and 3 third-grade classes in the school, how many students will attend an ass
2 answers:
For this case we have to:
If there are 26 students in each grade level class and we have three classes of this type, we multiply to know the number of students:
Now, if there is an assembly for third grade students, knowing that 4 students were missing, we subtract to know the number of students present:
Thus, 74 students will be present at the assembly.
Answer:
74

Answer:
425.25
Step-by-step explanation:
Since we are given 36th term as 14 and we know common difference is , it means that from the first term, we add
to each and get 14 on the 36th term. To figure out the first term, thus, we have to subtract
35 times from 14. Let's do it to get first term:
The sum of arithmetic sequence formula is:
Where,
is the sum of nth term (we want to figure this out for first 36 terms)
is the first term (we figured this out to be 9.625)
is the term number (36 for our case)
is the common difference (given as
)
Substituting all the values, we get:
First answer choice is right.
