What is the value of x that makes the given equation true? 2(x−8)=x+5x

Answers

Answer 1

Answer:

First simplify the right side by combining like terms.

Since both terms contain an x, you can add them together.

So x + 5x simplifies to 6x.

So our equation now reads 2(x - 8) = 6x.

Solving from here, distribute the 2 through the

parentheses on the left side of the equation.

2(x) is 2x and 2(-8) is -16.

So we have 2x - 16 = 6x.

Now move the 2x to the right side by subtracting 2x from both sides.

This gives us -16 = 4x.

Now just divide both sides by 4 to get -4 = x.

Answer 2

Answer:

Answer:

x = -4

Step-by-step explanation:

To find the value of x that makes a certain equation true means to solve the equation. You do this by rearranging the equation to make x the subject.

So,

2(x-8) = x+5x

2x - 16 = 6x

-16 = 6x-2x

4x = -16

x = -4

Answers

Answer:

the answer is 25

Step-by-step explanation:

cause -5 times -5 is 25 cause negative times negative is positive, and 5 times 5 is 25.

Well, -2 times -2 is 4 and 4 times -2 is -8 times -2 is 16 and 16 times -2 is -32 and -32 times -2 is 64 and -64 times -2 is 128

So 128

Ashley needs to ride her bike to her friends house 96 miles away. She is riding at an average rate of 15 miles per hour. She has 6 hours to get there. Will she make it?

Answers

The relationship between Speed, Distance and Time can be expressed as:

$\rm Distance = Speed * Time$

The total distance to be covered is 96 kilometres. Ashley couldn't cover it with existing speed and in available time.

Given:

$\rm{Average\; speed \;of\; Ashley} =(15\;mile)/(hour)$

$\rm{Time\; available} = 6\;hours$

Now, calculate the maximum distance that is possible to cover.

$\begin{aligned}\rm Distance &= \rm{Speed * Time}\n&=15 * 6\n&=90\end{aligned}$

The total distance to be covered by her is 96 kilometres. Ashley could cover only 90 kilometres.

Average speed of Ashley = 15 miles per hour

Time she has = 6 hours

Distance can be covered = speed × time = 15×6 = 90 miles

But the distance of her friend's house is 96 miles.

So she will not be able to make it.
