Answer:
x = 22
Step-by-step explanation:
Adding all the degrees to a triangle must equal 180
120 + (x+16) + x = 180
2x + 136 = 180
-136. -136
2x = 44

x = 22
Answer:
B.
Step-by-step explanation:
y = 3/4x + 2 slope: 3/4
perpendicular line slope: - 4/3
3(n + 5) ≥ 3n + 8
3n + 15 ≥ 3n + 8
3n - 3n ≥ 8 - 15
0 ≥ -7
Therefore, the solution to the inequality is all real numbers.
Combining like terms:
First do the first part which is 6(u-4)-8, you first distribute 6 to u and -4, 6u-24-8
-24-8=-32, 6u-32
Second part the same thing , distribute -6 to -4u and 6, (negative times a negative equals a positive) 24u-36-2u
24u-2u=22u
Solving:
6u-32=22u-36
Subtract 6u on both sides, -32=16u-36
Add 36 on both sides, 4=16u
Divide 16 on both sides
U=4/16 which is 0.25
