Mathematics

A rational number is: A number that can be written as a quotient of 2 integers, where the divisor is not 0.

Example: 2/5 , -6, 

Because you can write any integer as a quotient with a denominator of 1, all integers are rational numbers, 

Example: 5 = 5/1

(4x-y=-15)<br>(3x-2y=-10)<br>​
Andreyy89

Answer:

<h2>x = -4 and y = -1 → (-4, -1)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}4x-y=-15&\text{multiply both sides by (-2)}\\3x-2y=-10\end{array}\right\\\underline{+\left\{\begin{array}{ccc}-8x+2y=30\\3x-2y=-10\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad-5x=20\qquad\text{divide both sides by (-5)}\\.\qquad\qquad\boxed{x=-4}\\\\\\\text{Put the value of x to the first equation.}\\\\4(-4)-y=-15\\-16-y=-15\qquad\text{add 16 to both sides}\\-y=1\qquad\text{change the signs}\\\boxed{y=-1}

Kara partitions 16 dimes into equal groups in 3 different ways.  She puts more than1 dime in each group.  She makes 2 or more gr
qaws [65]
First look at all of the factors of 16:
(1, 16) (Cannot have only one group so this one does not work)
(2, 8) (this one is two equal groups of eight because 2x8 is 16)
(4, 4) (this one is four equal groups of four because 4x4 is 16)
(8, 2) (this one is eight equal groups of two because 8x2 is 16)

You can put it into two equal groups of 8 because 16/2 is 8
You can put it into four equal groups of 4 because 16/4 is 4
You can put it into eight equal groups of 2 because 16/8 is 2

I hope this helps!

Question 132 .. .. .. .. ..
Eddi Din [679]

Answer:

∠LOM is 48°

Step-by-step explanation:

∠MOL+∠MON=180°

6x°+12°+7x°-92°=180°

13x°-80°=180°

<em>Add 80° to both sides</em>

13x°=260°

<em>Divide both sides by 13</em>

x°=20°

Plugging x° into the equation for ∠LOM, we get:

7×20°-92°=

140°-92°=

48°

∠LOM is 48°
