-3x+13=16
Move +13 to the other side. Sign changes from +13 to -13.
-3x+13-13=16-13
-3x=16-13
-3x=3
Divide by -3 for both sides.
-3/-3x=3/-3
Cross out -3 and -3, divide by -3, then becomes 1*1*x=x
x=-1
Answer: x=-1
Cells through the process of respiration.
It’s 60.
A line has 180 degrees, if one half of the line has 120 degrees, then 180-120 = 60.

<span>y = -x3 + 5x2 - 11x + 55 ||x = 5 one root -125 + 125 - 55 + 55 = 0
using Synthetic Divsion
5 -1 5 -11 55
-5 0 -55
</span><span>-1 0 -11 0
results in:
-x^2 - 11 = 0
x^2 + 11 = 0
x^2 = -11
x = ± i√11
roots are: i√11,-i√11,5</span>
0.75 x 68 = 51
51 + 68 = 119
68 increased by 75% is 119.
