The cost of each Piano Lesson = $30
If there are x lessons, the total cost of lessons can be expressed as 30x.
Since the number of lessons cannot be negative, the value of x can be 0 or greater than 0, where x=0 shows no lesson.
For 1 lesson, x = 1
So the cost will be = 30(1) = $30
In ordered pair we can write it as (1, 30)
If we consider there is an option to attend half portion of a lecture, then for 1 and half lectures, x = 1.5
So, the cost for 1.5 lectures will be = 30(1.5) = $45
In ordered pair we can write it as (1.5, 45)
For 3 lesson, x = 3
The cost of 3 lessons will be = $90
In ordered pair we can write this as (3, 90)
So, from the given options, only following 2 ordered pairs satisfy the given conditions:
1) (1,30)
2) (3, 90)
Answer:
96
Step-by-step explanation:
Basically you're multiplying how many coins you have that year by eight.
The fist year you had 4 coins. 4 multiplied by 8 equals 32. Mrs Bradford had 32 coins.
The second year you had 6 coins. 6 multiplied by 8 equals 48. Mrs Bradford had 48 coins.
The third year you had 8 coins. 8 multiplied by 8 equals 64. Mrs Bradford had 64 coins
For the fourth and fifth year you have to add 2 for each year.
So for the 4th year you had 10 coins and 10 multiplied by 8 equals 80. Mr.Bradford had 80 coins.
And Finally for year five you had 12 coins. 12 multiplied by 8 equals 96. Mr.Bradford had 96 coins in year five.
According to my calculations it should be 77
Answer:
the total time is 18 hours remaining
Just think of 4/8. Four is half of 8, right? therefore, it is 1/2. 4/8 reduced is 1/2
