Complete question
<em>18. GOLF Luis and three friends went golfing. Two of the friends rented clubs for $6 each. The total cost of the rented
</em>
<em>clubs and the green fees for each person was $76. What was the cost of the green fees for each person? Define a
</em>
<em>variable, write an equation, and solve the problem.</em>
The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16
Let the cost of green fees per person be y
If Luis and three friends went golfing, this means that 4 people went golfing. The total cost of green fees for all of them will be $4y
If two of the friends rented clubs for $6 each, total amount spent will be $2(6)
The equation that models the statement will then be expressed as;

Solve for y

The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16.

use the order of operations for this equation.
multiplication comes first.
11(11) - 6(17) + 4
121 - 102 + 4
for addition and subtraction, order doesn’t matter.
121 - 102 = 19
19 + 4 = 23
answer = 23
Answer:
Step-by-step explanation:

Product of a number and its multiplicative inverse should be equal to 1.
So,

Assuming the sequence goes on like this 11,-33,99,-297,891,...,
its general formula is

So, the 9th term is
