Yuson used her calculator to solve the equation
Tpy6a [65]

Answer:

Rather than just multiplying 5/4 with 8, she has to multiply it with 3 + 8. She could put parentheses around the 3 + 8, according to PEMDAS, this would mean that the parenthesis must be solved before multiplication. The correct answer would be:

4/5x - 8 = 3

4/5x = 3 + 8

x = (3 + 8)5/4

x = 11 x 5/4

x = 55/4 or 13.75

If 2k, 5k-1 and 6k+2 are the first 3 terms of an arithmetic sequence, find k and the 8th term​
Klio2033 [76]

Answer:

see explanation

Step-by-step explanation:

The common difference d of an arithmetic sequence is

d = a_{2} - a_{1} = a_{3} - a_{2}

Substitute in values and solve for k, that is

5k - 1 - 2k = 6k + 2 - (5k - 1)

3k - 1 = 6k + 2 - 5k + 1

3k - 1 = k + 3 ( subtract k from both sides )

2k - 1 = 3 ( add 1 to both sides )

2k = 4 ⇒ k = 2

--------------------------------------------------------

The n th term of an arithmetic sequence is

a_{n} = a_{1} + (n - 1)d

a_{1} = 2k = 2 × 2 = 4 and

d = 5k - 1 - 2k = 3k - 1 = (3 × 2) - 1 = 5

Hence

a_{8} = 4 + (7 × 5) = 4 + 35 = 39
