18. You can do this in a calculator. 26 - 8 = 18. v = 18.
The answer is 7,500 because 150% is the same as 1.5 x 5000.
Answer:
Option (1)
Step-by-step explanation:
Given equation is,

To determine the solution of the equation we will substitute the values of 'x' given in the options,
Option (1)
For x = -0.75

0.59 = 1 - 0.44
0.59 = 0.56
Since, values on both the sides are approximately same.
Therefore, x = -0.75 will be the answer.
Option (2)
For x = -1.25

0.42 = 1 - 0.25
0.42 = 0.75
Which is not true.
Therefore, x = -1.25 is not the answer.
Option (3)
For x = 0.75

1.68 = 1 - 2.28
1.68 = -1.28
Which is not true.
Therefore, x = 0.75 is not the answer.
Option (4)
For x = 1.25

2.38 = 1 - 3.95
2.38 = -2.95
It's not true.
Therefore, x = 1.25 is not the answer.
Answer:
See below.
Step-by-step explanation:
1)
So we have:

This can be interpreted as:
"There exists a natural number <em>x</em> and an integer <em>y</em> such that x² is equal to y²."
2)
So we want even numbers are in the set of integers.

This is interpreted as:
"The set of even numbers (2n such that n is an integer) is in the set of integers"
