 Your equation is 1/5 + 1/3 =1/x To solve you have to find the common denominator which is 15 So (1/5)3 and (1/3)5

                                          = 3/15+5/15=8/15

                                                  8/15=1/x now cross multiply

                                                   =15/8

This is the answer I got.

Solve by factoring:<br> 5t=t ^2
elena-14-01-66 [18.8K]

Answer:

t=0 and t=5

Step-by-step explanation:

5t = t^2

Subtract 5t from each side

5t-5t = t^2 -5t

0= t^2 -5t

Factor out a t

0= t(t-5)

Using the zero product property

t=0  and t-5 =0

t=0  and  t-5+5=0+5

t=0 and t=5
