The answer should be 101.
The value of -7² is less than zero which is the correct answer would be an option (D)
<h3>What is the fraction?</h3>
A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
<h3>What are Arithmetic operations?</h3>
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
To determine the value is less than zero
Option A: (-6)² ⇒ 36
So this value is greater than zero
Option B: 1/3 × 2 ⇒ 2/3
So this value is greater than zero
Option C: 0.5² ⇒ 0.25
So this value is greater than zero
Option D: -7² ⇒ -49
So this value is less than zero

Responder:
Número total de bolas = 245/23
Explicación paso a paso:
Dado que:
Bolas blancas = 1/5
Bolas negras = 1/7
Bolas rojas = 7
Sea el número total de bolas = x
Bolas blancas = 1 / 5x
Bolas negras = 1 / 7x
Por tanto, total;
(x / 5 + x / 7 + 7) = x
((7x + 5x) / 35) +7 = x
(12x / 35) + 7 = x
7 = x - 12x / 35
7 = (35x - 12x) / 35
7 = 23 veces / 35
245 = 23x
x = 245/23
