300 messages would have to be sent or received in order for the plan to cost same each month.
Step-by-step explanation:
Given,
Cost per month = $30
Per text sent or received charges = $0.10
Let,
x be the number of texts sent or received.
A(x) = 0.10x+30
A comparable plan costs = $60 per month
Text messages are unlimited.
B(x) = 60
For the two plans to cost equal;
A(x) = B(x)
Dividing both sides by 0.10
300 messages would have to be sent or received in order for the plan to cost same each month.

Answer:
S' (-6, 6)
T' (2, 6)
U' (2, 0)
V' (-6, 0)
Step-by-step explanation:
To reflect the rectangle over the x-axis, think of it as flipping it over the x-axis. On the graph, count the units from V to S, it's 6 units. So, from the x-axis, count 6 units up from V. S would lie on -6, 6. Do the same for W to T. T would lie on (2, 6). The remaining coordinates U and V don't change because it is <em>already </em>on the x-axis. <em> </em>
It is .15 because 1/8 in decimal forma is .125
Answer:
<u>Range = 1 1/4</u>
Step-by-step explanation:
Range = Maximum - Minimum
Arranging the data in ascending order :
- <u>1/2, 5/8, 3/4, 1 1/4, 1 1/2, 1 3/4</u>
<u />
Solving for range :
- Range = 1 3/4 - 1/2
- Range = 1 3/4 - 2/4
- Range = 7/4 - 2/4
- Range = 5/4
- <u>Range = 1 1/4</u>
The equation is:
55 + 10 x = 20 + 15 x, where x is number of the weeks.
55 - 20 = 15 x - 5 x
35 = 5 x
x = 35 : 5
x = 7
Answer:
The same amount of money in both accounts will be after 7 weeks.
