Answer 3

solve \[20\sqrt{273+t}=315\] is how i read it

Answer 4

takes 3 steps
a) divide by 20
b) square both sides
c) subtract 273

Answer 5

so how would I start square 273 and t?

Answer 6

divide what by 20

Answer 7

@satellite73

Answer 8

both sides

Answer 9

takes 3 steps
a) divide both sides by 20
b) square both sides
c) subtract 273 from both sides

Answer 10

315/20=15.75

Answer 11

ok so \[\sqrt{273+t}=15.75\] square both sides to get rid of the radical

Answer 12

15.75x15.75=248.0625

Answer 13

so what do i do now?

Answer 14

ok only one more step

Answer 15

\[273+t=248.0625\] subtract \(273\) from both sides to get t

Answer 16

-24.9375

Answer 17

ok

Answer 18

so the answer would be none of these?
