Answer:

-1 5/28

Step-by-step explanation:

-3/7 + (-3/4)

Get a common denominator of 28

-3/7 *4/4 = -12/28

-3/4 *7/7 = -21/28

-12/28 + -21/28

-33/28

-28/28 - 5/28

-1 5/28

Answer:

a) The value of $n$ is 81.30.

b) The value of $n$ is 81.

Step-by-step explanation:

a) The value of $n$ is the ratio of the mass of the Earth to the mass of the Moon. That is:

$n = \frac{5.972\times 10^{24}\,kg}{7.346\times 10^{22}\,kg}$

$n = 81.30$

The value of $n$ is 81.30.

b) If $n$ is a integer, then the result must have only two significant figures. Given the result, we must approximate to the closest integer. That is:

$n = 81$

The value of $n$ is 81.

Which orders paid is a solution is the equation y= 4x + 9

Verizon [17]

<em>Note: you did not add the answer options, so I am solving this question generally to solve your query, which anyways would clear your concept.</em>

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

$y= 4x + 9$

All we need is to find any random value of 'x' and then solve for 'y'.

For example, putting x=2

$y= 4x + 9$

$y=4(2)+9$

$y=8+9$

$y=17$

Thus, (2, 17) is one of the many ordered pairs solutions of the equation.

Similarly, putting x=3

$y= 4x + 9$

$y=4(3)+9$

$y=12+9$

$y=21$

Thus, (3, 21) is one of the many ordered pairs solutions of the equation.

What is the equation of a line that passes through the point (8, 1) and is perpendicular to the line whose equation is y=−2/3x+5

Anuta_ua [19.1K]

Answer:

$y = \frac{3}{2} x-11$

Step-by-step explanation:

We are to find the equation a line that passes through the point (8, 1) and which is perpendicular to a line whose equation is $y = - \frac{2}{3} x+5$ .

We know that the slope of line which is perpendicular to another line is the negative reciprocal of the slope of the other line so it will be $\frac{3}{2}$ .
