Complete Question
Jessica pays a flat rate of $70 for her cell phone and is charged $0.05 for every text she sends. Jessica wants to spend less than $80.00 per month on her cell phone. Write and solve an inequality that shows how many text messages Jessica must limit herself to in order to keep her monthly bill less than $80.00.
Answer:
<em>Inequality: </em>70 + 0.05x < 80
<em>Solution: </em>x < 200
Step-by-step explanation:
Let x represents the minimum number of SMS.
If 1 SMS is charged at $0.05, then x SMS would be charged at $0.05x
Considering that she pays a flat rate of $70.
The inequality to represent the minimum number of SMS she needs to send is:
70 + 0.05x < 80
To solve this inequality, follow the following steps
Collect like terms
0.05x < 80 - 70
0.05x < 10
Divide through by 0.05
0.05x/0.05 < 10/0.05
x < 10/0.05
x < 200
The solution to the inequality that shows how many text messages Jessica must limit herself to in order to keep her monthly bill less than $80.00 is x < 200.
Answer:
4 by 2
Step-by-step explanation:
you can basically guess and check with this question but I knew if it was a rectangle then 2 sides would be larger than the other. So I started off figuring out what times what equals 8 and I got 2 and 4. So I put those in for the side lengths and I got 12.
Answer:
0.5789
Step-by-step explanation:
The successful events would be 34 , 40 41 42 43 44 45 46 47 48 49
The total number of ways 19 when you count from 31 to 49
P(1 four) = 11/19 = 0.5789
