Answer: the golfer would need to play golf 10 times per year.
Step-by-step explanation:
Let x represent the number of times per year that the golfer need to play golf for the two options to cost the same.
A social membership costs $1775 in annual dues. In addition, he would pay a $65 greens fee and a $25 golf cart fee every time he played. This means that the total cost of playing golf for x times with the social membership option is
1775 + (65 + 25)x
A golf membership costs $2425 in annual dues. With this membership, the golfer would only pay a $25 golf cart fee when he played. This means that the total cost of playing golf for x times with the golf membership option is
2425 + 25x
For the costs to be the same,
1775 + 65x + 25x = 2425 + 25x
65x + 25x - 25x = 2425 - 1775
65x = 650
x = 10
Answer:
Width of 9cm and length of 17cm.
Step-by-step explanation:
To calculate an area of a rectangle, use the formula A=l*w. We know the length is 8cm longer than the width. So l = 8 + w. So the area is A= (8+w)*w.
We also know the area is 153. Substitute this value for A and solve.
To solve the quadratic, use the quadratic formula:
Here a=1, b=8 and c=-153.
Since w=9 or w=-17, substitute this value for w in l= 8+w to find l.
l = 8+9 = 17
or
l=8+-17 = -9
Since length cannot be positive, it must be l=17 and w=9.
The answer is x = 15
The equation would be x + 2 = 17
Answer:
#3
Step-by-step explanation:
If it is parallel to the x axis it has 0 slope, and that means its y=y value. The y value here is 13 so,
It has a slope of zero and an equation of y=13
