Answer:
n <=6.5
Step-by-step explanation:
Six less than two times a number is no more than 7
2n-6 <=7
Add 6 to each side
2n-6+6 <=7+6
2n <=13
Divide by 2
2n/2 <=13/2
n <=6.5
1,096.79
because
700*(1+.05/12)
Answer:
I use equal signs throughout but they are meant to be less than or equal to signs.
s=sandwiches
4.5s+6 less than or equal to 50
The answer is s is less than or equal to 12
Step-by-step explanation:
Finding Inequality
1. we know everything costs 50 in total so that is on one side of the equal sign.
____=50
2. we know he already spent 6 dollars so the money he can spend is 6 dollars less.
____+6=50
3. Each sandwich costs 4.50 $ so how much money does he have left to spend? we figure that out by multiplying the price by the number of sandwiches.
4.5s+6=50
Solving
1. 4.5s-6=50
First use the addition property of equality and add 6 to both sides.
2. 4.5s=56
Then use the division property of equality and divide each side by 4.5
3. you get a decimal but since you can't buy half a sandwich the answer is
s is less than or equal to 12
Answer: A because it goes from (0,infinity) so all positive real numbers
<span> The exponent is negative so we factor out -1:
