Given: m zorp = 80°
mzorn = (3x + 10),
prove: x = 30
which statement could be used in step 2 when proving x =
30?
statements

80° (3x + 10)
zorp and zorn are a linear pair
zorp and zorn are vertical angles
80 = 3x +10
x = 30

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
