\dfrac{x-3}5 = \dfrac{x+5}3 \\\\\implies 3(x-3)  = 5(x+5)\\\\\implies 3x - 9 = 5x +25\\\\\implies 5x -3x +25 +9 =0\\\\\implies 2x +34 =0\\\\\implies 2x = -34 \\\\\implies x = -\dfrac{34}2 =-17

\sf \longmapsto \:  \dfrac{x - 3}{5}  =  \dfrac{ x  + 5}{3}

\sf \longmapsto \: 3(x - 3) = 5(x + 5)

\sf \longmapsto \: 3x - 9 = 5x + 25

\sf \longmapsto3x - 5x = 25 + 9

\sf \longmapsto - 2x = 34

\sf \longmapsto \: x =  \dfrac{34}{ - 2}

\sf \longmapsto \: x =- \cancel  \dfrac{34}{ 2}

\sf \longmapsto \: x = -  17

\boxed{\Rightarrow\:  x = - 17}

How do you subtract an integer from another integer without using a number line or counters? Give an example.
torisob [31]
If they are two positive numbers, do it normally. If there is a negative and a positive, change it to addition and switch the SECOND integer sign. Only works with two integer…s in a subtraction question.

<h3>4 Answers: A, C, E, and F</h3>

================================================

Explanation:

Choice A is true assuming we have a_n = (-1)^n*b_n

In this case, a_n = (-1)^n*\frac{1}{\sqrt{n}} and b_n = \frac{1}{\sqrt{n}}

--------

Choice B is false. See choice A above.

--------

Choice C is true. The sequence \{b_n\} is decreasing. As n gets larger, b_n gets smaller. This is because the denominator is growing larger with the numerator held constant.

--------

Choice D is false. This contradicts choice C.

--------

Choice E is true since the denominator is growing forever

This is similar to  \displaystyle \lim_{n \to \infty} \frac{1}{n} = 0

--------

Choice F is true due to choices C and E being true.  

--------

Choice G is false because it contradicts choice F.

What are the steps to this equation to -2x-4+5x=8
laila [671]

Answer:

x = 4

Explanation:

−2x − 4 + 5x = 8

[ Simplify both sides of the equation ]

−2x − 4 + 5x = 8

−2x + −4 + 5x = 8

(−2x + 5x) + (−4) = 8 (Combine Like Terms)

3x + −4 = 8

3x − 4 = 8

[ Add 4 to both sides ]

3x − 4 + 4 = 8 + 4

3x = 12

[ Divide both sides by 3 ]

3x / 3 = 12 / 3

x = 4
