2x + 3 = 4x - 3<br><br> Please help & explain how to get to the answer

krok68 [10]

I assume we are solving for x?

You need to isolate x on one side of the equation.
subtract 4x from both sides. This leaves -2x+3=-3. Because we need to isolate x we subtract 3 from both sides, leaving -2x=-6. Again we isolate x, divide both sides by -2. x=3

2x+3=4x-3
-2x+3= -3
-2x= -6
x=3

Helen's house is located on a rectangular lot that is1 1-8 miles by 9/10 mile.Estimate the distance around the lot

klemol [59]

Answer: The distance around the lot is given by

$4\frac{1}{20}\ miles$

Step-by-step explanation:

Since we have given that

Length of rectangular lot is given by

$1\frac{1}{8}\\\\=\frac{9}{8}\ miles$

Width of rectangular lot is given by

$\frac{9}{10}\ mile$

We need to find the distance around the lot.

As we know the formula for "Perimeter of rectangle":

$Perimeter=2(Length+Width)\\\\Perimeter=2(\frac{9}{8}+\frac{9}{10})\\\\Perimeter=2(\frac{45+36}{40})\\\\Perimeter=2\times \frac{81}{40}\\\\Perimeter=\frac{81}{20}\\\\Perimeter=4\frac{1}{20}\ miles$

Hence, the distance around the lot is given by

$4\frac{1}{20}\ miles$
