34 square inches I think you just divide the number in half.
Add the numbers: 57 + 39 + 76 + 87 + 91 = 350;
Divide by how many numbers (i.e. we added 5 numbers): 350 ÷ 5 = 70;
<span>So the average is 70;</span>
Answer:
The quart bottle of cola for $1.50 is the better buy.
Step-by-step explanation:
In order to compare the amount of cola per cost, you need to first use the same measurements. Since one bottle is a quart and one bottle is a liter, we need to convert one to the other. There are approximately 1.06 quarts per liter. So, for the quart bottle, we can also say it has 1.06 liters of cola. To find the price per volume, we take the cost divided by the volume: 1.50 ÷ 1.06 = $1.42. The liter bottle costs $1.57. So, the quart bottle would be cheaper overall by approximately $0.15.
<span>m/5 + 3(m - 1) = 2(m - 3)
m + 15(m - 1) = 10(m - 3)
m + 15m - 15 = 10m - 30
6m = -15
m = -15/6</span>
