Complete question

18. GOLF Luis and three friends went golfing. Two of the friends rented clubs for $6 each. The total cost of the rented

clubs and the green fees for each person was $76. What was the cost of the green fees for each person? Define a

variable, write an equation, and solve the problem.

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;

$4y + 2(6) = 76\\$

Solve for y

$4y + 2(6) = 76\\4y+12 = 76\\4y = 76 - 12\\4y = 64\\y =\frac{64}{4}\\y = 16$

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

$(2x-8)(7x+5)=0\iff2x-8=0\ \vee\ 7x+5=0\\\\2x-8=0\qquad\text{add 8 to both sides}\\2x=8\qquad\text{divide both sides by 2}\\\boxed{x=4}\\\\7x+5=0\qquad\text{subtract 5 from both sides}\\7x=-5\qquad\text{divide both sides by 7}\\\boxed{x=-\dfrac{5}{7}}$
