When multiplying positive and negative fractions, you have to find a common denominator. true or false for 25 points and brainliest

Answer:

1/81

Step-by-step explanation:

[tex](-1/3) ^4\\\\\mathrm{Apply\:exponent\:rule}:\\\quad \left(-a\right)^n=a^n,\:\quad \mathrm{if\:}n\mathrm{\:is\:even}\\\\\left(-\frac{1}{3}\right)^4=\left(\frac{1}{3}\right)^4\\\\\mathrm{Apply\:exponent\:rule}:\\\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}\\\\\left(\frac{1}{3}\right)^4=\frac{1^4}{3^4}\\\\1^4=1\\3^4=81\\\\=\frac{1}{81}[/tex]

The value of [tex]\((-1/3)^4\)[/tex] using property of exponents is [tex]\(\dfrac{1}{81}\)[/tex].

To simplify the expression [tex]\((-1/3)^4\)[/tex], calculate the power of the numerator and the denominator separately.

[tex]\((-1/3)^4 = \left(\dfrac{-1}{3}\right)^4\)[/tex]

Now, let's simplify each part:

[tex]\(\left(\dfrac{-1}{3}\right)^4 = \dfrac{(-1)^4}{3^4}\)[/tex]

Using the exponent property

[tex](\dfrac{a}{b} )^4 = \dfrac{a^4}{b^4}[/tex]

[tex]\(\dfrac{(-1)^4}{3^4} = \dfrac{1}{3^4}\)[/tex]

The denominator [tex]\(3^4\)[/tex] means 3 raised to the power of 4, which equals 81.

[tex]\(\dfrac{1}{3^4} = \dfrac{1}{81}\)[/tex]

Therefore, [tex]\((-1/3)^4\)[/tex]simplifies to  [tex]\(\dfrac{1}{81}\)[/tex].

I just got that question,  good luck

Answer:

Step-by-step explanation:

Given the subtraction problem;

2.25-(-0.25)

First we will need to open up the parenthesis by multiplying the signs. product of two negative signs will result in a positive. Hence the equation becomes;

= 2.25+0.25

Convert to fraction;

= 225/100 + 25/100

Find the LCM

= (225+25)/100

= 250/100

= 2.50

Hence the difference of both values on the number line is 2.5

Step-by-step explanation:

Hey there!

Given;

= 3(2x-7) + 1/3(7x+2)

Let's simplify them.

[tex] = 3(2x - 7) + \frac{1}{3} (7x + 2)[/tex]

[tex] = 6x - 21 + \frac{7x + 2}{3} [/tex]

[tex] = \frac{3(6x - 21) + 7x + 2}{3} [/tex]

[tex] = \frac{18x - 63 + 7x + 2}{3} [/tex]

[tex] = \frac{25x - 61}{3} [/tex]

Therefore the answer is (25x-61)/3.

Answer:

Elio is correct.

Step-by-step explanation:

Only Elio is correct; he used the Zero Product Property correctly for both factors. For [tex]-3n-8=0[/tex], he correctly got [tex]n=-\frac{8}{3}[/tex]. For [tex]2n+4=0[/tex], he remembered to subtract [tex]4[/tex] from both sides to get [tex]2n=-4[/tex], which yields [tex]n=-2[/tex] as the other solution.

Step-by-step explanation:

Answer:

12 inches

Step-by-step explanation:

10 x 12 = 240

0.5 x 240 = 120

0.10 x 120 = 12

you do 10 x 12 to fid the total miles, you can also find it by doing 240 x 0.10.

then you do 240 x 1/2 because it is 1/2 inch per mile.

then you divide the answer to that by 10 because there are 10 inches per mile.

Step-by-step explanation:

Move 2x to the right side of the equation and it becomes -7y= -2x + 24 and then divide by -7 and then it becomes y = 2/7 x -24/7

Answer:

2x - 7y = 24

2x - 24 = 7y

7y = 2x - 24

y = (2x - 24)/7

= 2/7x - 24/7
