will give medal and fan for best help. I have tried this problem time and time again and i can't get the right answer. please help. (posting equation below)
\[3d+d-7=\frac{ 25 }{ 4 }\]
Ok so first things first, what is 3d + d equal to?
4d
right so now you got 4d - 7 = 25/4 now add 7 across so you get 4d = 25/4 + 7
How can you simplify 25/4 + 7?
it would be \[13\frac{ 1 }{ 4 }\]
Right so now you have 4d = 13 1/4 or thats the same as 53/4 so ill sticl with 53/4 4d = 53/4 so how do you get d by itsself?
divide by 4
yes! so d = 53/4 / 4 which is equal to?
\[53/4 \div 4\] to make it look prettier :P
3 5/16
yes. now you know what d is :)
thanks a ton!
