What are the steps to solve this?<br> 9+6(x-5)=10-3(x-7)
Aliun [14]
<h2><u>Solve for x</u></h2>

<h3>what are the steps to solve this?</h3><h3>9+6(x-5)=10-3(x-7)</h3>

<u>Step 1:</u> Apply distributive property.

  • 9 + 6(x - 5) = 10 - 3(x - 7)
  • 9 + 6x - 30 = 10 - 3x + 21
  • -21 + 6x = 31 - 3x

<u>Step 2:</u> Combine all like terms.

  • -21 + 6x = 31 - 3x
  • -21 - 31 = -6x - 3x
  • -52 = -9x

<u>Step 3:</u> Divide both sides of the equation by -9 and simplify.

  • -52/-9 = -9x/-9
  • 52/9 = x

<u>Answer:</u>

  • The value of x is <u>52/9</u>.

Can someone help me with this math homework please!
sladkih [1.3K]

Answer:

1st option.

0 to 100 miles per hour

Step-by-step explanation:

as we can see the question states that a particular car' s gas mileage DEPENDS upon its speed.

Since, the independent variable is the domain of the function the speed of the car will act as the domain of the given function.

out of all the option option 1 gives us values of speed( cause its unit is miles/ hour - unit of speed).

so the domain is

0 to 100 miles per hour.

If triangle ABC is similar to triangle EHG, find the measure of angle EHG.
Ksju [112]

<u>First we need to find all the interior angles.  So we know that the inside of a triangle (all the angles added up) equals 180. So we need to equal all the inside angles to 180. </u>

2x + x + 60 = 180

<u>Now lets start to solve. First let's subtract the 60 from both sides. </u>

2x + x = 120

<u>Now we need to add the x's together. </u>

3x = 120

<u>Now we must divide the 120 by 3 to get x by itself. </u>

x = 40

<u>Now just replace the x with 40 to find each of the sides. I'm guessing the triangles are reflecting each other so </u><em><u><EHG would be equal to 80. </u></em>

<u>ALSO to check if 40 would be correct, add all the angles together in the same triangle and they SHOULD add up to be 180! Which they do! </u>
