Answer:
The first one
Step-by-step explanation:
Counterexample is an example with a negative connotation. Whereas an example may be used to support or illustrate a claim, a counterexample is used to refute an assertion.
<u>Statement:</u> All whole numbers are even.
<u>Counterexample:</u> Consider numbers 3, 5, 7, 9, 11, 13, 15, 17, 19, 21,.... These numbers are whole numbers, but not even numbers.
You give an example of whole numbers that are not necessarily even.
Prime numbers are number that can't be divided except it is it's self and 1. For example, 3,5,7,11,13,17, 19, 23, 29, 31, 37...... All of those numbers can only be divided with itself and 1.
3 = 3x1
7 = 7x1
23= 23 x 1
hope this helps
A pair of fractions that have the same product is 1/2 and 2/4 because they are both half.
Hope I helped! Also I hoped this is what you meant by the finding a pair of fractions with same products. :D
0.50a + .65p = 10
0.50 a + .65(10)=10
0.50a + 6.5=10
Subtract 6.5 from both sides
0.50a=3.5
Divide both sides by0.50
Apples= 7
