Answer:

(2n -3) + n = 102

2n - 3 + n = 102

3n - 3 = 102

3n = 105

n = 35 (the first number)

SO...

The other number is (2 x 35) - 3 =

                                           70 - 3 = 67 (the second number)

The numbers are 35 and 67.

35 + 67 = 102 CHECK!

The simplified form of the expression; (3/4)-¹ as given in the task content is; 4/3.

<h3>What is the simplified form of the expression as given in the task content?</h3>

It follows from the task content that the expression in discuss can be simplified as follows by the laws of indices;

(3/4)-¹

Hence, due to negative exponent, the result is;

= 1 ÷ (3/4)¹

= 1 × (4/3)

= 4/3.

Given the functions f(n) = 11 and g(n) = -2(n - 1), combine them to create an arithmetic sequence, an, and solve for the 31st te
FromTheMoon [43]

Answer:

Option A is correct

a_n = 11-2(n-1) and  a_{31} = -49

Step-by-step explanation:

Given the functions:

f(n) = 11

g(n) = -2(n-1)

then;

combine them to create an arithmetic sequence i.e,

a_n = f(n)+g(n)

⇒a_n = 11-2(n-1) where n is the number of terms

To find the 31st term.

Substitute n =31 we have;

a_n = 11-2(31-1)

⇒a_{31}=11-60 = -49

Therefore, we have an arithmetic sequence,

a_n = 11-2(n-1) and  a_{31} = -49
