Hi there!

Begin by distributing the 5:
5(2x) + 5(-12) = -90
Simplify:
10x - 60 = -90
Add 60 to both sides:
10x = -90 + 60
10x = -30
Divide both sides by 10:
x = -3
Answer:
As the givens set A contains 24 elements.
Therefore,
The Cardinality of the set A = 24
Step-by-step explanation:
Let the given set is A
A = {x: x is a positive counting number less 25}
The set of natural numbers is often termed as the Counting number set.
-
As the counting numbers are less than 25.
Thus,
Set A will be:
<u>The Cardinality of the set</u>
The Cardinality of the set represents the total number of elements in a given set.
As the givens set A contains 24 elements.
Therefore,
The Cardinality of the set A = 24
Answer:
C. x > 5 or x < - 3
Step-by-step explanation:
Step 1:
x - 1 > 4
x > 4 + 1
x > 5
Step 2:
x - 1 < -4
x < -4 + 1
x < -3
HP: {x > 5 or x < -3} (c)
What is NOT true about the solution is that it can have different values
