2x - 1 + 3x + 6 = 90°
5x + 5 = 90
5x = 90 - 5
5x = 85
x = 85/5
x = 17°
If the number is big enough there can be up to an infinite number of decimals
The answer is incorrect. 142 / 3 equals forty-seven with a remainder of one, and the question is saying it equals fifty-two with a remainder of four and asking whether it is true or false. If it’s the R part you’re confused about, R means remainder, or the amount left behind when the division problem is solved. Hope this helped!
