4b+1 equivalent to -2(b+4)+3
I believe it is 25 x^2. So your answer would be 25.
8 is 53.8
Cuz 66.93-6.57x2= 53.78 rounded to the nearest tenth 53.8
3,4,7 just plug the x into the equation
Hi there!

First we rearrange the sum in order to add both of the fractions first. We can rearrange because the only thing we need to do is adding.

Add the fractions.
** If you don't get this, think of this story: you lack 1/3 of an apple pie and someone gives you 2/3 of pie. How much pie do you have left?
- 1 / 3 + 2 / 3 = 1 / 3 **

Finally add 4 to our found fraction.

Therefore, the answer is 4 1/3.
