Rewrite the expression in the form k\cdot x^nk⋅x n k, dot, x, start superscript, n, end superscript. 2\sqrt x\cdot 4x{^{^{-\scriptsize\dfrac52}}}=2 x ⋅4x − 2 5 =2, square root of, x, end square root, dot, 4, x, start superscript, start superscript, minus, start fraction, 5, divided by, 2, end fraction, end superscript, end superscript, equals

To calculate this you’ll have to subtract and then divide
1500= 500+50t
1.) subtract 500 from 1500 to break down the equation
1500-500 =500+50t -500
1000= 50t
2.) now you want to get t alone... so since t is multiplied by 50, you will do the opposite and divide 50 from 1000 in order to get rid of it- which will again break down the equation
1000 /50= 50t /50
20= t

The answer is 20 minutes
Hope this helps x
