Answer:
0
Step-by-step explanation:
Zero is a rational number, and we know that the integer 0 can be written in any one of the following forms. ... Thus, 0 can be written as, where a/b = 0, where a = 0 and b is any non-zero integer. Hence, 0 is a rational number and not an integer.
4 times 200=800
4 times 70= 280
4 times 5= 20
add it together and you get 1100
Answer:
5x3=15
15x5=75
75x7=525
Step-by-step explanation:
What you have to do for this is to divide the total worth ($200,000.00) by the number of shares.
So this means that we need to count:
200 000 ÷4 000
here's a trick:
if you divide two numbers with many 0s at the end, you can always erase the SAME mount of 0s at the end (this is equivalent to dividing by 10).
so
200 000 ÷4 000
is equivalent to :
200 ÷4
which is 50! (4*50=200)
so the answer is that each share was worth 50 dollars.
For this case we have the following equations:
revenue: y = 4x
cost: y = 1 / 2x + 280
We must match both equations:
4x = 1 / 2x + 280
From here, we clear the value of x:
4x-1 / 2x = 280
7 / 2x = 280
x = (2/7) * (280)
x = 80
Answer:
jason needs to sell 80 posters so that the cost and revenue are equal
