3x - y = 9
y = -2x + 11
3x - (-2x + 11) = 9
3x + 2x - 11 = 9
3x + 2x = 9 + 11
5x = 20
x = 20/5
x = 4
y = -2x + 11
y = -2(4) + 11
y = -8 + 11
y = 3
solution (where the lines intersect) is (4,3)
Answer:
If he spins a spinner with 5 equal sections they have equally likely probability of 20%
If he rolls a fair die in the shape of pyramid with 4 sides each side has probability of 25%
If he rolls a fair die in the shape of cube with 6 sides each side has probability of 16.7
Total number of outcomes = 5 * 6 * 4 = 120
Answer:
staurant has an all-you-can-eat buffet. They charge $13.95 per person. what is the constant of proportionality?
Step-by-step explanation:
You have to work this out step-by-step.
Population started at 1000.
It went up 10%: 1000 + 10%(1000) = 1000+100 = 1100
Now it's 1100
It then went down 20%: 1100 - 20%(1100) = 1100 - 220 = 880
Now it's 880.
It then went back up 10%... I'll let you try the last calculation.
Can you take it from there?
