p = 7 + 0.46x is the monthly cost for x text messages
<u>Solution:</u>
Given that, A text message plan costs $7 per month plus $0.46 per text
To find: Monthly cost for "x" text messages'
Let "x" be the number of text messages in a month
From given information,
text message plan cost per month = $ 7
Cost for 1 text = $ 0.46
Let "p" be the Monthly cost for "x" text messages
Then, we get,
p = text message plan cost per month + (Cost for 1 text)(number of text messages in a month)
Thus the monthly cost for x text messages is found

Step-by-step explanation:
The lateral surface area is given by pi*r*l, we can use trigonometry to find l. 8*sqrt(3)/l=sin(60), l=16 and r is given by tan(60)=8*sqrt(3)/r, r=8. The lateral surface area is 16*8*pi=128*pi
Answer:
1. c 2. a 3. b
Step-by-step explanation:
The best way to prove these results are the right ones is by multiplying diagonally :
1. 1/3 = 4/12 -----> 1 . 12 = 12 ; 3 . 4 =12
2. 1/2 = 3/6 ------> 1 . 6 = 6 ; 2 . 3 = 6
3. 2/5 = 6/15 -----> 2 . 15 = 30 ; 5 . 6 = 30
The results of the multiplications must be the same if the fractions are equivalent.
