15% of 33 =
= 15% * 33
= 0.15 * 33
= 4.950 students in that class are left-handed
5,040 I think because 7•6•5•4•3•2•1=5040
The answer is B) 4:5
First write the ratio out. To find the simplified expression, divide by the greatest common factor (GCF). In this case, the GCF of 28 and 35 is 7.
28:35

=4:5
4:5 is the simplest form because you cannot simplify it further.

Answer: -5 < x < 2</h3>
Explanation:
The expression -2x means -2 times x. To undo this, we divide all parts of the inequality by -2. Dividing by a negative number will flip the inequality sign. We go from "less than" to "greater than"
-4 < -2x < 10
-4/(-2) > x > 10/(-2) .... inequality signs flip
2 > x > -5
-5 < x < 2
This unknown number x is between -5 and 2. It cannot equal -5. It cannot equal 2.
