Solve the equation 29 - (x+8) = 6x - 7

max2010maxim [7]

First step you should do is simplify both sides of your equation:
29-(x+8)=6x-7
Distribute the Negative Sign:
29+-1(x+8)=6x-7
29+-1x+(-1)(8)=6x-7
29+-x+-8=6x-7
29+-x+-8=6x+-7
Combine Like Terms:
(-x)+(29+-8)=6x-7
-x+21=6x-7
Subtract 6x from both sides:
-x+21-6x=6x-7-6x
-7x+21=-7
Subtract 21 from both sides:
-7x+21-21=-7-21
-7x=-28
Divide both sides by -7:
-7x/-7 = -28/-7
And now your answer should be:
x=4

Find the distance between each pair of points. round your answer to the nearest tenth.

goldenfox [79]

Answer:

5.4

Step-by-step explanation:

To find the distance between each pair of points, we use the distance formula, which is:

d = $\sqrt{(x_{2}-x_{1})^2 + (y_{2} -y_{1})^2 }$

So we have

$x_{1} = 2\\ x_{2} = 4\\y_{1} = 8\\y_{2}=3$

When we plug in the values into the formula we get:

d = $\sqrt{(4-2)^2 + (3-8)^2}$

d = $\sqrt{4 + 25}\\ =\sqrt{29}\\ =5.4$

Which of the following shows the solution to the inequality

otez555 [7]

Answer:

I got x = 1

Step-by-step explanation:

First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:

$1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1$
