X ÷ 2 - 13 = 1
Write the division as a fraction

Multiple both sides of the equation by 2

Reduce the number with greatest common divisor 2

Multiply the numbers

Then u will have

Move constant to the right by adding its opposite sides

Eliminate the opposites

Then you have

Add the numbers
The sum total of the angles in a triangle is equal to 180° degrees.
Answer:
Incorrect.
Step-by-step explanation:
Let, the first number is x, and the second number is y. Given, the second number is 125% of the first number. So, the equation will be
y = 1.25 x
Or, y= 5/4x
Now, multiplying it with 4/5, we get, x= 4/5y
Or, x= 0.80 y
But, Brad is saying the first number must be 75% of the second number. But here we see that the first number is 80% of the second number. That's why Brad is incorrect.
The representation of the equation given in the task content; 2/5 v + 3/4 = 2/3x² as a s sentence is; The sum of Two-fifths of a number, v and quarters is equal to two-thirds of the square of the number x.
<h3>What is the representation of the equation as given in the task content?</h3>
It follows from the convention that the following fractions can be named as follows;
- 2/5 means two-fifths.
- 3/4 means three-quarters.
- 2/3 means two-thirds.
Hence, it follows from the iterations above and how they relate to the equation given in the task content that the representation is; The sum of Two-fifths of a number, v and quarters is equal to two-thirds of the square of the number x.
