Answer:
102 tickets
Step-by-step explanation:
Let's say the total number of tickets sold is n.
7n = 2142
n = 2142 ÷ 7
n = 306
They sold 306 tickets in total.
We want to know how much they sold per night. We know they sold the same number of tickets each night for three nights.
306 ÷ 3 = 102
Therefore, they sold 102 tickets each night.
I hope this helps :)
Hello.
To find the percentage of how many students went on the field trip, we simply divide 18 by 25.
18/25 = 0.72
Convert decimal into fraction.
0.72 = 72%
Thus, 18 out of 25 students = 72% of students who are going on the field trip.
You're welcome.
Step-by-step explanation:
The x-intercept is at (-3, 0). To find the slope of the perpendicular line, let's rewrite the equation to its slope-intercept form, which is
y = (2/3)x + 2
This means that the perpendicular line has a slope m = -3/2. So the slope-intercept form of this new line is
y = -(3/2)x + k. Since this line passes through (-3, 0), we cal solve for k:
0 = -(3/2)(-3) + k or k = -9/2
So our equation becomes (slope-intercept form)

or in its standard form,

Answer:
z = 70
Step-by-step explanation:
Explanation: To solve this proportion for z, we can use cross products.
When we get the equation 5z = 350, we can get z by itself on the left side of the equation by dividing both sides of the equation by 5. On the left, the 5's cancel each other out and we have z. On the right, 350 divided by 5 simplifies to 70 so we have z = 70.
