X = large boxes and y = small boxes
x + y = 70.....x = 70 - y
60x + 65y = 4300
60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs
x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
Answer:

Step-by-step explanation:
Given:
'C' represent total cost of lease. 'd' represents cost of sales in dollars.
Cost of 1 square foot of building = $0.75
Total area of the building = 500 square feet.
Sales tax on the total sales = 2.5%
Now, cost of 500 square feet area = Cost of 1 square foot × Total area
Cost of 500 square feet area = 
Now, sales tax is 2.5 of total sales 'd'. This gives,
Sales tax = 
Now, total cost is the sum of least amount and total sales tax.
Total cost = Least amount + Sales tax
⇒ 
Yes it’s true
The answer comes out as 31,311
So 1,878,66 is divisible by 6 Is TRUE

<h2>
The Parallelogram</h2>
Step-by-step explanation:
A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same). NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
Also, we have two pairs of parallel sides: is parallel to , and is parallel to . So it is a parallelogram or a rhombus. Since the length of the sides are not equal, the quadrilateral is a parallelogram.
