X/4 is the same as 1/4x, so you have the equation 1/4x + 7 = 5. subtract 7 to both sides to get the equation 1/4x = -2. then you multiply by four (which is the same as dividing by 1/4) to get x = -8

To all people who are good at math<br> please help me answer this question, I will give 30 points

sesenic [268]

Answer:

=》n = 10

Step-by-step explanation:

here's the solution :-

=》

$2(n - 9) - 1 = 1$

=》

$2(n - 9) = 1 + 1$

=》

$2(n - 9) = 2$

=》

$n - 9 = \frac{2}{2}$

=》

$n - 9 = 1$

=》

$n = 1 + 9$

=》

$n = 10$

hence, the value of n = 10

Simplify radical using the exponent rule. Show work

katen-ka-za [31]

Answer:

$\frac{1}{x^{4} }$

Step-by-step explanation:

( $\sqrt[3]{x^{2} }$ × $\sqrt[6]{x^{4}}$ )⁻³

$\sqrt[3]{x^{2} }$ is the same thing as $x^{\frac{2}{3} }$

you can think of the numerator as the power and the denominator as the root

rewrite both terms:

( $x^{\frac{2}{3} }$ × $x^{\frac{4}{6} }$ )⁻³

simplify the 4/6:

( $x^{\frac{2}{3} }$ × $x^{\frac{2}{3} }$ )⁻³

bases are the same, add the exponents:

( $x^{\frac{4}{3} }$ )⁻³

multiply the exponents:

$x^{\frac{-12}{3} }$

simplify:

x⁻⁴

negative power rule:

$\frac{1}{x^{4} }$

P is the centroid of triangle MNO. MP=14x+8y. write expressions to represent PR and MR number 22 on sheet

gavmur [86]

Answer:

PR = 7x +4y
MR = 21x +12y

Step-by-step explanation:

The centroid is 1/3 the distance from the side to the opposite vertex. Hence ...

... PR = (1/3)(MP + PR)

... 3PR = MP + PR . . . . . . multiply by 3

.. 2PR = MP . . . . . . . . . . . subtract PR

... PR = MP/2 = (14x +8y)/2 . . . . . divide by 2, substitute for MP

... PR = 7x +4y

Of course, MR = MP + PR, so ...

... MR = (14x +8y) + (7x +4y)

... MR = 21x +12y
