Answer:

1/3

Step-by-step explanation:

1/3, 2/6, 3/9, 4/12.

are equivalent fractions. Equivalent fraction of a given fraction is got by multiplying or dividing its numerator and denominator by the same whole number.

The given fraction 4/12 is equivalent to 1/3 which means that both fractions represent the same value.

To find a fraction equivalent to 4/12, we need to simplify it by reducing the numerator and denominator to their lowest terms.

In this case, the GCD of 4 and 12 is 4. When we divide both the numerator and denominator by 4, we get:

4/12 = (4 ÷ 4) / (12 ÷ 4)

= 1/3

Therefore, 4/12 is equivalent to 1/3.

This means that both fractions represent the same value, but the fraction 1/3 is in its simplest form, where the numerator and denominator have no common factors other than 1.

The correct question is as follows:

What fraction is equivalent to 4/12?

Answer:

It increases

Step-by-step explanation:

The mean of the given data set of 8 values is 4.75 ([tex]\frac{2+4+5+6+8+2+5+6}{8}[/tex])

Adding 7 into the data set also increase the number of data points to 9, so the mean becomes:[tex]\frac{2+4+5+6+8+2+5+6+7}{9}[/tex], which is equal to 5

Answer: $378.33

Step-by-step explanation:

First we calculate the Simple interest which will be:

= 12000 × 4.5% × 3

= $1620

Since there are 36 monthly installments, the amount of the monthly payments would be:

= $13620 / 36

= $378.33

Answer:

The value of x is 20.

Step-by-step explanation:

Given that

Number of songs Marcus has = 10x+8

Number of songs Lara has = 15x-92

It is also given that they have the same number of songs that means both the expressions should be equal.

Putting both equal

[tex]10x+8 = 15x-92[/tex]

This is a linear equation in one variable which can be solved using properties of equality

Subtracting 10 from both sides

[tex]10x+8-10x = 15x-92-10x\\8 = 5x-92[/tex]

Adding 92 on both sides

[tex]8+92 = 5x-92+92\\100 = 5x[/tex]

Dividing both sides by 5

[tex]\frac{5x}{5} = \frac{100}{5}\\x = 20[/tex]

Hence,

The value of x is 20.

Answer:

B. 36a^2b^2

Step-by-step explanation:

1. Apply exponent rule: (-a)^n = a^n, if n is even

(-6ab)^2 = (6ab)^2

(6ab)^2

2. Apply exponent rule: (a × b)^n = a^nb^n

(6ab)^2 = 6^2a^2b^2

6^2a^2b^2

3. 6^2 = 36

36a^2b^2

In other words, your answer is B.

The answer is Option B)

In Algebra, the like terms are defined as the terms that contain the same variable which is raised to the same power. In algebraic like terms, only the numerical coefficients can vary. We can combine the like terms to simplify the algebraic expressions.

Given here: (-6ab)²=36a²b²
