Answer:

The answer is t=1/9

Step-by-step explanation:

If we substitute sqrt(t) = u, then we can write the equation as 3u^2+5u-2=0.

Using the quadratic formula, we can solve that u = 1/3 and u = -2.

We can go back to our original substitution and say that sqrt(t) = 1/3. The sqrt(t) can not be -2 because a square root can not be negative.

If we solve the equation sqrt(t) = 1/3, we get that t=1/9.

Answer:

−4

s−t+

−4

Step-by-step explanation:

Let's solve for c.

3s+2t−3c−7s−5t=4

Step 1: Add 4s to both sides.

−3c−4s−3t+4s=4+4s

−3c−3t=4s+4

Step 2: Add 3t to both sides.

−3c−3t+3t=4s+4+3t

−3c=4s+3t+4

Step 3: Divide both sides by -3.

−3c

−3
