Answer:

The answer is answer D, x=42.

Step-by-step explanation:

To isolate the variable, you need to divide both sides of the equation by three, using the division property of equality. 126/3=42 , and 3x/3=x , this gives you 42=x, or x=42, meaning the answer is D.

Rewrite -4/15 as an equivalent fraction
timofeeve [1]

(\frac{-4}{5} ) in the form of Equivalent Fraction can be written as \frac{-4x}{15x}, where "x" is any integer.

As per the question statement, we are provided with a fraction, (\frac{-4}{5} ).

We are required to rewrite the above mentioned fraction in the form of a general Equivalent Fraction.

To solve this question, we need to know what an equivalent fraction is.

Equivalent fractions are those fractions that have different numerators and denominators but are equal to the same value, when simplified.

For example, (\frac{1}{2}, \frac{2}{4}, \frac{3}{6}, \frac{4}{8}) all equate to \frac{1}{2} when simplified.

Now, for this case, equivalent fractions of (\frac{-4}{5} ) are (\frac{-8}{30}, \frac{-12}{45}, \frac{-16}{60},...), where

\frac{-8}{30}=\frac{(-4)*2}{15*2}\\\frac{-12}{45}=\frac{(-4)*3}{15*3}\\ \frac{-16}{60}=\frac{(-4)*4}{15*4}

i.e., the equivalent fractions of (\frac{-4}{5} ) are in the form of  \frac{-4x}{15x}, where "x" can be any integer, (...-6, -5, -4, -3, -2, -1, 2, 3, 4, 5, 6...)

Tell whether the given value is a solution of the inequality.<br><br> a/6 &gt; -4; a = -18
balandron [24]

First we simplify the inequality

1. <em>multiply 6 by the other side of the inequality (-4) </em>

Now we have ...

a > -24

Anything that can be a solution to the inequality <u>must be greater than -24</u>

-18 is greater than -24

This means that, YES! a = -18 IS a solution to the inequality

Multiply using the distributive property (X+4)(X^2+6x-3)​
yan [13]

Answer:

x^3 + 10x^2 + 21x - 12

Step-by-step explanation:

(x + 4)(x^2 + 6x - 3)

you can separate to make it easier for u

x(x^2 + 6x - 3) + 4(x^2 + 6x - 3), this is optional u don't have to do this part

x^3 + 6x^2 - 3x + 4x^2 + 24x - 12

add like terms together

x^3 + 10x^2 + 21x - 12
