Keep, Change, Flip! 3/14 * 10/7...multiply straight across and 3*10 w/ 14*7
Your answer would be 30/98
Divide those both by 2 and your final answer is 15/49
Let, the number of hour, she can still watch the T.V. = x
Equation would be: x + 1.5 ≥ 5
Solving the equation:
x + 1.5 ≥ 5
Subtract 1.5 from both the sides,
x + 1.5 - 1.5 ≥ 5 - 1.5
x ≥ 3.5
In short, She can watch 3.5 hours more in that week
Hope this helps!
Answer:
The given table is
Quantity(x) Price(y)
1 2.00
2 3.50
3 5.00
4 6.50
5 8.00
6 9.00
It means the points on the graph are (1,2), (2,3.50), (3,5), (4,6.50), (5,8) and (6,9).
The graph 1 represents all the above mentioned point, therefore option 1 is correct.
According to the graph 2, at quantity 6 the price of flower is 12, which is not correct. Therefore option 2 is incorrect.
The quantity of flower is always a whole number. So the graph is defined on the whole numbers only. It means the graph is a scatter plot instead of a curve of a straight line.
Therefore the option 3 and 4 are incorrect.
Step-by-step explanation:
The answer would be (6,0)
1.
Let the number of months be xLet y = cost
y = 125 + 10x
2.
For a full year, x = 12 since there are 12 months in a year.
y = 125 + 10x = 125 + 10 * 12 = 125 + 120 = 245
The cost is $245
3.
Let the number of downloads be x.Let y = cost.
y = 50 + x
4.
50 + x = 245
x = 195
Answer: You can download 195 songs.
5.
Downloading 14 songs per month means downloading 168 songs per year since 12 * 14 = 168
Option 1 cost:
For 12 months: y = 125 + 10x = 125 + 10 * 12 = 125 + 120 = 245Option 1 costs $245
Option 2 cost:
y = 50 + x = 50 + 168 = 218
Option 2 costs $218
Answer: Option 2 is more cost effective.
