Answer:
adults : 0 children: 600
Step-by-step explanation:
x + y = 600
6x＋4y = 2400
4×(x + y = 600) = 4x＋4y = 2400
(6x＋4y = 2400) － (4x＋4y = 2400) = x=0
so y=600
Answer:
Step-by-step explanation:
Given that:
Tip left = $1.30
Tax = 7%
Tip = 10% of after tax cost
The tax percentage is not needed in calculating the bill after tax and tip
Hence,
Let after tax cost = x
10% of x = 1.30
0.1x = 1.30
x = $13
After tax cost = $13
Hence, the Total bill after tax = $13
Answer:
(a) x > 4 (b) y < -2
Step-by-step explanation:
Domain is referring to the x-values while the range is referring to the y-values.
Since the function (the line) has a circle at the point (4, -2), the function will be exclusive at that coordinate.
The line goes to infinity for the x-values from 4, so you write x > 4 or ∞ > x > 4.
Similarly, the line goes to infinity for the y-values from -2, so you write y < -2 or -∞ < y < -2.
Answer:
100 minutes
Step-by-step explanation:
1 hour = 60 minutes.
(2 / 3) * (1 hour) =
40 minutes
So the movie was 1 hour 40 minutes
REMEMBER:
1hr = 60 mins
60 mins + 40 mins = 100 mins
Hence, the answer is 100 mins
