Let the number of pages read on day 1 be = x
Then on day 2 he read twice the pages from day one, it is = 2x
On 3rd day he read 6 pages less than 1st day, it is = x-6
Total pages are = 458
The equation becomes: 
So on the third day, Aiden read 
pages.
Let the youngest sister be n years
Lana will be 2n years, as her youngest sister is half her age
The age of the twins separately will be 2n-2 as they are 2 years younger than Lana
So, the equation looks like this:
n + 2n + 2(2n-2) = 45
Now solve for n:
3n + 4n - 4 = 45
7n - 4 = 45
7n = 49
n = 7
So the youngest sister is 7, Lana is 14 and the twins are 12. 14 + 12 + 12 + 7 =45
<u>Answer:</u>$68.69
<u>Step-by-step explanation:</u>
Calculation of bill value
Cheeseburgers = 26.25
(8.75 x 3)
Fish Sandwich = 6.75
Pizza = 14.99
Sweet Tea
(4 x 2.09) = 8.36
Total of items = 56.35
Sales tax on food = 3.381
(56.35 x 6%)
Total bill value = 59.731
Calculation of tips
Bill value x 15%
=59.731 x 15%
Tips paid=8.95965
Calculation of meals cost
Total meal cost = Bill value + tips
=59.731+8.95965
=$68.69
Total meal cost is $68.69
Answer:
(B) 18.
Step-by-step explanation:
We are asked to find the perimeter of a quadrilateral with vertices at (-1, 4), (7,4), (7,5), and (-1. 5).
First of all, we will draw vertices of quadrilateral on coordinate plane and connect the vertices as shown in the attached photo.
We can see that our quadrilateral is a parallelogram, whose parallel sides are equal.
Therefore, the perimeter of the given quadrilateral is 18 units.
Answer: 60 cm three squared
You can observe in the picture attached that the box is a rectangular prism.
The volume of a rectangular prism can be found with this formula:
Where "l" is the length, "w" is the width and "h" is the height.
You know that the lenght of each side of those cubes is 1 centimeter. Therefore, you can multiply the number of cubes on each side of the box by 1 centimeter in order to find the lenght, the width and the height of the box:
Now you can substitute the lenght, the width and the height of the box into the formula shown at the beginning of the explanation:
Finally, evaluating, you get that the volume of the box is:
223 units
