the property of a rectangle two opposite sides are the same. meaning the length that is X must have the same length on the other side right. Same thing as the side 2 4/5. so there are 2 of that same number. you're basically multiplying it by 2
expression
2x + 2(2 4/5) = P
if you don't understand that it's basically like this
x + x + 2 4/5 + 2 4/5 = P (it's the same as the above expression)
P = perimeter of rectangle
Answer:
384 and a half.
Step-by-step explanation:
Took me a while, but just add 48 for every 2 minutes.
Let the number of units of the first type be x and the number of units of the second type be y.
A. You expect to sell at least 100 printers this month. This means that:
A + B >= 100
For simplicity, we will work on the equal sign (A + B = 100) which is the minimum number of units to be sold.
This can be rewritten as: A = 100 - B .................> equation I
B. You expect to make a minimum profit of 4400. This means that:
50A + 40B >= 4400
Again for simplicity, we will work on the equal sign (50A + 40B = 4400) which is the minimum profit to be made
50A + 40B = 4400 ..................> equation II
Substitute with equation I in II:
50 (100-B) + 40B = 4400
5000 - 50B + 40B = 4400
5000 - 4400 = 50B - 40B
600 = 10B
B = 60
Substitute in equation I:
A = 100 - B = 100-60 = 40
Therefore, to minimize your cost and achieve your goals in number of selling units and profits:
you should buy at least 40 units from the first type and 60 units from the second type
Answer:
2 hours
Step-by-step explanation:
30×1=30
30×2=60
That is true. It is the Pythagorean Theorem.
