Simplify 5x + 20 = 100

You have to remember that what you do to one side you must do the to the other. You want to isolate the x, so to do that you have to move everything to the other side by and by doing this you do the opposite. You want to remove +20 from the left side, so by doing that you do -20. Your equation is then 5x=80. You still want to isolate just the x, so to do this you divide by 5 and you have to do that to the other side as well. Therefore your answer it x=16 :)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
