Answer:
1 is correct
2 is incorrect
3 is incorrect
4 is incorrect
5 is correct
Step-by-step explanation:
1. 2(0.5+3) = 1+6 = 7
2. 1/2(0.5+3) = 1/4+3/2 = 7/4
3. 6(0.5+4) = 27
4. 1/6(0.5+4) = 0.75
5. 6(0.5+4) = 27
Answer: 74
Step-by-step explanation:
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
Answer:
1.8 inches
Step-by-step explanation:
Create a proportion where x is the distance on the map
=
Cross multiply and solve for x
55x = 99
x = 1.8
So, the distance on the map is 1.8 inches
Formula for finding the area of a circle:
We need to radius but we only have the diameter.
Luckily for us, if you have the diameter, you have the radius.
Because the radius is the diameter over 2.
10 / 2 = 5
Plug in the values.
A = (3.14)5^2
A = (3.14)25
A = 78.5
So, the answer is 78.5.
