Move the constant to the right
5k=7-6
calculate
5k=1
solution: k=1/5 or k=0.2
B, because it says she has gone up 5 times Andre (a).
Easey peasy
oposite angle is equal
other angles are supplementary (supplementary means add to 180, and a straight line=180 so if you look at 2 lines intersecting and think for a little bit, you wiill see why)
oposite angle=30
other angle is adds to 180
30+other=180
subtract 30
other=150
other is oposite other other
other=other other
150=other other
angles are
150,30,150
