Answer:
(a) The ones that are equivalent to the given fraction are: 
and 
(b) The one that is equivalent to the given fraction is: 
Answer:
x=6
y=9
z=10
Step-by-step explanation: The long 20 on the left has 4, 6 and _10_ to make 20. The blank which is 10 is the same length as z. The proportion of 10/15 translates throughout the whole shape. That means it is 6/9 and 4/6.
The simplified proportion is 2/3 by the way.
Answer:
x = 6 , z = 79
Step-by-step explanation:
(8x + 53) and (6x + 43) are adjacent angles and sum to 180° , that is
8x + 53 + 6x + 43 = 180 , that is
14x + 96 = 180 ( subtract 96 from both sides )
14x = 84 (divide both sides by 14 )
x = 6
Then
6x + 43 = 6(6) + 43 = 36 + 43 = 79
z and 79 are vertical angles and congruent , then
z = 79
