Can you rearrange it so T is the subject

OverLord2011 [107]

The formula after making t subject of the formula is:

$t = \frac{2-3q}{q+4}$

Step-by-step explanation:

Given formula is:

$q = \frac{2-4t}{t+3}$

To make t the subject of the formula we have to isolate t

So,

Cross-multiplying

$q(t+3) = 2-4t\\qt+3q = 2-4t$

Adding 4t on both sides

$qt+3q+4t = 2-4t+4t\\qt+3q+4t = 2$

Subtracting 3q from both sides

$qt+3q+4t-3q = 2-3q\\qt+4t = 2-3q$

Taking t common on left hand side

$t(q+4)=2-3q$

Dividing both sides by q+4

$\frac{t(q+4)}{q+4}=\frac{2-3q}{q+4}\\t = \frac{2-3q}{q+4}$

The formula after making t subject of the formula is:

$t = \frac{2-3q}{q+4}$

The city council is planning to construct a park on North Street that has a triangular perimeter. They want to place a fountain

Nadya [2.5K]

In this case they would want to put the fountain exactly in the middle of the triangle, since "equidistant" in this case means "equally distant", and this occurs at the exact center of the triangle.
