Solve the equation 6x+7=8x-15

Answer:

X = 11

Step-by-step explanation:

So, in order to solve this equation, we need to isolate x.

So, we are going to subtract 8x from the right side to get the x on one side. The equation should look like this:

-2x + 7 = -15

Now in order to get x all alone on one side, we need to subtract 7 from the left side.

-2x = -22

Now we just have to divide the -2 from x.

X = 11

Answer:

x = 11

Step-by-step explanation:

6x + 7 = 8x - 15

Step 1: Subtract 8x from both sides.

6x+7−8x=8x−15−8x

−2x+7=−15

Step 2: Subtract 7 from both sides.

−2x+7−7=−15−7

−2x=−22

Step 3: Divide both sides by -2.

-2x/-2 = -22/-2

x = 11

blsea [12.9K]

Answer:

1. diameter=8 kilometres

2. area=98.96 inches

3. 37m

Step-by-step explanation:

1. diameter= 2*radius

2. area of sector=θ out of 360*πr^{2} where θ is the angle

3. area of garden=πr^{2}

        706.5=πr^{2}

     r^{2}=706.5/π

        = 225(nearest whole)

     r=\sqrt{225}=15m

we now use Pythagoras theorem to find length of each pathway

40^{2} =15^{2} +x^{2}

1600=225+x^{2}

x^{2}=1600-225=1375

x=\sqrt{1375}=37 m (to nearest whole)
