10 is the initial value, found when x=0. I don't know what you are measuring by "0" and "10" here, so can't be more specific.
I don't know how to get the answer, but i know the answer is 127.50.
It doesnt mean they are false it just means the person giving the study is going to favor something over something else in the study. Hes basically picking favorites.
Answer:
x = 24 , y = 19
Step-by-step explanation:
(2x + 13) and 47 + 3x are same- side interior angles and sum to 180° , so
2x + 13 + 47 + 3x = 180 , that is
5x + 60 = 180 ( subtract 60 from both sides )
5x = 120 ( divide both sides by 5 )
x = 24
Then 3x = 3 × 24 = 72
5y - 23 and 3x are corresponding angles and are congruent , then
5y - 23 = 72 ( add 23 to both sides )
5y = 95 ( divide both sides by 5 )
y = 19
