What is the solution to the rational equation x over 2x plus 1 minus 1 over 4 equals 2 over 2x plus 1

aalyn [17]

We want to solve
$\frac{x}{2x+1} - \frac{1}{4} = \frac{2}{2x+1}$

Subtract 2/(2x+1) from each side.
$\frac{x}{2x+1} - \frac{2}{2x+1y} - \frac{1}{4} = 0$

Add 1/4 to each side, and simplify the left side.
$\frac{x-2}{2x+1} = \frac{1}{4}$

Cross multiply.
4(x - 2) = 1(2x + 1)
4x - 8 = 2x + 1

Simplify and solve for x.
4x - 2x = 1 + 8
2x = 9
x = 9/2 or x = 4 1/2.

Answer: $x = \frac{9}{2} \,\, or \,\, x = 4 \frac{1}{2}$

Which of the following sets of lengths could not be the side lengths of a triangle?

docker41 [41]

To find out if the three side lengths can create a triangle, the three smaller lengths must be greater than the longer length.

$\bf~Option~A$

$\sf~3~meters,5~meters,7~meters$

$\sf3+5=8>7$

So this can create a triangle.

$\bf~Option~B$

$\sf1~yard,1.25~yards,1.5~yards$

$\sf1+1.25=2.25>1.5$

So this can create a triangle.

$\bf~Option~C$

$\sf5~inches,10.5~inches,17~inches$

$\boxed{\sf5+10.5=15.5$

So this cannot create a triangle.

$\bf~Option~D$

$\sf15~millimeters,18~millimeters,30~millimeters$

$\sf15+18=33>30$

So this can create a triangle.

Therefore, your answer is Option C.
