Answer:
3. x=50, y=80, 4. x=6.5, y=5
Step-by-step explanation:
I think, not entirely sure.
For better understanding think of it this way. There are hundred customers, 60 orders coffee 35 orders pie and 30 does not order pie or coffee.
This means that 70 does order coffee or pie or both. Out of those 70 people 10 will not order coffee and 35 will not order pie. Thus 70-10-35=25 will order both coffee and pie.
P=0.25

Answer:
400 times Greater
Step-by-step explanation:
8 x 10^4
10^4 = 10000
10000 x 8 = 80000
2 x 10^2
10^2 = 100
2 x 100 = 200
= 400
Answer:
1-3x+8y
Step-by-step explanation:
Multiply y and 2
Multiply y and 1
The y just gets copied along.
2*y evaluates to 2y
Multiply x and 4
Multiply x and 1
The x just gets copied along.
The answer is x
4*x evaluates to 4x
2*y-4*x evaluates to 2y-4x
The answer is 2y-4x+8
2*y-4*x+8 evaluates to 2y-4x+8
Multiply y and 6
Multiply y and 1
The y just gets copied along.
The answer is y
6*y evaluates to 6y
2y + 6y = 8y
The answer is 8y-4x+8
2*y-4*x+8+6*y evaluates to 8y-4x+8
-4x + x = -3x
The answer is -3x+8y+8
2*y-4*x+8+6*y+x evaluates to -3x+8y+8
8 - 7 = 1
The answer is 1-3x+8y
2*y-4*x+8+6*y+x-7 evaluates to 1-3x+8y
