Write an equation for the nth term of the arithmetic sequence.
2 answers:
6(n-1)+3
a50= 297
Of course, your formula would work as well..
Answer:
an = 3 + 6 (n-1)
the 50th term is 297
Step-by-step explanation:
We know that the formula used to find the nth term of a sequence is given by:
an = a₁ + d(n - 1)
where an is the nth term, a₁ is the first term and d is the common difference.
In this case a₁ = 3, d = 6 and n =50.
Therefore:
an = 3 + 6(49) = 3 + 294 = 297.

Answer:
6 ways
Step-by-step explanation:
The way to solve for this is to use the formula
Combination C (n-1, r-1)
= n = 5 identical fruits
r = 3 bowls
So, we have: 5 - 1 = 4
3 - 1 = 2
= 4!/2! (4-2)!
= 4 × 3 × 2 × 1/(2 × 1 )(2 × 1)
= 6 ways

Sophie factored it completely while Carlos did not.
Complete factoring is achieved when all factors other than monomial factors are prime factors. Carlos' (4x + 2) can still be factored into 2(x+1).
Answer: There are 40 cars and 5 motorcycles at the end of buying and selling. He started with 9 motorcycles and 36 cars.
Step-by-step explanation:
x=# of motorcycles 4x=# of cars
8(x-4)=4x+4
8x-32=4x+4
4x=36
x=9
---
4(9)+4=36+4=40
9-4=5
