The answer to day 3 is A :)
You can go through the set and test each one out:
x=0:
2(0)+3 ≥ 7? Or 3≥7? No
x=0.6:
2(0.6)+3≥7? 4.2≥7? No.
x=2:
2(2)+3≥7? 7≥7? Yes.
x=4:
2(4)+3≥7? 11≥7? Yes.
x=6:
2(6)+3≥7? 15≥7? Yes.
The set is {2, 4, 6}.
Answer:
15
Step-by-step explanation:
Multiply: 25x.60=15
The reason why you multiply 25 times .60 is because you need to change the percentage to a decimal. The way you change you from a percentage to a decimal is by moving the decimal twice to the left.
So, 60%=.60
To do a two-column proof, you must know the definitions of the terms that are being used. Also, you must know the postulates and theorems you have learned so far. You look at the given information, and using the definitions, postulates, and theorems, you reason in your mind how to go from the given to the conclusion, step by step. You write each step and the accompanying reason that allows you to conclude each step.
