Answer:
Step-by-step explanation:
I can only do the first one, and then only by brute force. If both numbers can be the same, then David would write 143143
143 * 143 = 20449
7 * 20449 = 143*143. It is the only answer that came up from 100 to 999.
If I get the second one, I'll put it in the comments. But I can only do it by brute force as well, if I can do it at all.
Answer:
the answer is true

Last Question
Because this may not be the question you want, I'll omit the first step which should be done with latex. The key to all of these except C is to invert the second fraction (turn the second fraction upside down) and multiply.
A
=(6*-2) / (5*3) = - 12/15 = -4/5
B
= (7*5) / (4*3) = 35 / 12 = 2 11/12
C
Impossible to do 4/0 cannot be done.
D
= (-2*-4)/(3*5) =
8/15
Answer:
0.333333+
Step-by-step explanation:
Hello there!
You expect to sell 100% - 20% = 80% of many coffee sales.
0.80 * 1500 = 1200
Your answer is 1200 cups of coffee.
Hope I helped!
