Google the fist question
hint --- hex means 6 and pent means five
13 + y = -3
-13 = -13 add
-----------------
13-13 + y = -16
y = -16
=============================
3y + 8=3
-8 = -8 add
---------------
3 y + 0 = -5
y = -5/3
=============================
y over 3= -9
3 (y/3) = 3 (-9)
y = -18
how many side and angles does a trapezoid angle, hexagon, and pentagon have?
solve each equation:
13 + y = -3, 3y + 8=3, y over 3= -9
need help with + & - rules for adding whole numbers, decimals, fractions and integers ( do not understand) and rule for multiplying + & -
