technically, you need to put in a second variable, x, at the end of the equation.
Assuming that in a parallelogram, angle A = 78 degrees angle B = 3y degrees and that angles A and B are adjacent interior angles of the parallelogram. 78 + 3y = 180 so 3y = 102 and so y = 102/3 = 34 degrees.
75
-10 + 7x + 4x = 78 Collect like terms -10 + 11x = 78 Add '10' to both sides 11x = 88 Divide both sides by '11' 11x/11 = 88/11 x = 8 The answer!!!!!
78
78+78-:(85)/(78)+7,879=1405
78 + 89 + 167 + 897 + 78 = 1309
55 + 82 + 92 + 78 + 100 + 96 + 78 = 581
78 + 78 = 156
The absolute value is just determining how far the number is away from "0". -78 is 78 numbers away from zero, thus the absolute value of -78 is 78.
78
2 + 2 + 78 = 82
84+73+78 = 235.
