12) This one would be (b) because if you were reading it out loud it would be 2 is less than 3x, and 3x is greater than 5.
13) To make this easier for you I would change everything to a decimal. Peaches: 3.25 pounds Mangos: 4.35 pounds Since the peaches are .89 per pound you times 3.25(.89)=2.8925 (which rounds to 2.89) Since the magpies cost 1.26 per pound you would times 4.375(1.26)=5.5125 (rounds to 5.51) Then 5.51-2.89=2.62 So the answer is A
14)3x is greater than or equal to nine In this case x would have to be three or greater. So the answer would be B
15) The answer is B
16)c — -5=20 2 You first get rid of your constant which in this case is -5, so you add 5 to both sides. C — -5=20 2 +5 +5 Then you would get C — =25 2 Now you want to try to get the variable alone, so you cancel the twos out, what you do to one side you have to do to the other. 2 C — =25(2) 2 C=50 The answer is D
We have 10 pieces of paper. The probability of drawing a 10 is 1/10. Therefore, if we were to draw ten times, the ten should probably be drawn once. If we multiplied our number of drawings by four (10*4=40), our outcome of seeing our slip with the ten should also quadruple and become four times. (1*4=4)
