Answer:
You need to add more context to the question. I cannot answer it without knowing what "These scales" are.
Answer:
3x=-x-60
Step-by-step explanation:
Let, the salary before raise = s

Answer:
a) 0.900
b) 0.400
Step-by-step explanation:
Let I = households getting internet
T = households getting television
Then I = 60%
and T = 80%
(Households that get both services)
a) Households getting at least one service, ![I\cup T = I + T - I\cap T= 60+80-50 =90\%=0.900](https://tex.z-dn.net/?f=I%5Ccup%20T%20%3D%20I%20%2B%20T%20-%20I%5Ccap%20T%3D%2060%2B80-50%20%3D90%5C%25%3D0.900)
b) Those getting internet only = ![I - I\cap T = 60 - 50 = 10\% = 0.1](https://tex.z-dn.net/?f=I%20-%20I%5Ccap%20T%20%3D%2060%20-%2050%20%3D%2010%5C%25%20%3D%200.1%20)
Those getting television only = ![T - I\cap T = 80- 50=30\%=0.3](https://tex.z-dn.net/?f=T%20-%20I%5Ccap%20T%20%3D%2080-%2050%3D30%5C%25%3D0.3)
Probability of getting exactly one service = 0.1 + 0.3 = 0.400
Answer:
c) 30
Step-by-step explanation:
since the lines are parallel, 75° = 2x + 15°
this is because when two parallels lines are intersected by the same line, all respective angles are equal. Also, opposite angles on a line are equal too.
So now that u have 75 = 2x + 15, just solve for x by simplifying:
75 = 2x + 15
60 = 2x
30 = x
so the answer is c) 30
