2n/3
the difference means divide 2 times(multiply)a number
180-50=130
x-y=130
x+y=50
2x=180
x=90
90+y=50
y=50-90
y=-40
The first answer is ''Linear pair postulate''
The second answer is ''Definition of suplementary''
The third answer is ''m∡ACB+45=180''
The fourth answer is ''Subtraction Property of Equality''
The fifth answer is ''∡ACB is obtuse''
The sixth answer is ''Definition of obtuse triangle''
Good luck!!!
Given:
3n + 5
n = 1 ; 3(1) + 5 = 3 + 5 = 8
n = 2 ; 3(2) + 5 = 6 + 5 = 11
n = 3 ; 3(3) + 5 = 9 + 5 = 14
n = 4 ; 3(4) + 5 = 12 + 5 = 17
The first four terms of the sequence are: 8, 11, 14, 17. Second option.
Area = length x width
21 = length x 5
length = 21/5 = 4.2
The length is inversely proportional to the width because as the length increases the width reduces and vice-versa
