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
You keep adding 2 and 1/3 to get your answer
<span>It is calculated as follows:
1.446x10^9/6.025x10^4=0.24x10^5=2.4x10^4. Therefore, the answer is 5.) 10^5</span>
Let's start by solving this equation using distribution method:
4(x - 3) = 2x + 7
4x - 12 = 2x + 7.
Move like terms on one side:
4x - 2x = 7 + 12
2x = 19
x = 9.5
Let's plug in x for 4x-3:
4x - 3
4 * 9.5 - 3
38 - 3
35
4x - 3 = 35
