Answer:
x = 20
Step-by-step explanation:
50 - 38 = 12
a^2 + b^2 = c^2
16^2 + 12^2 = x^2
256 + 144 = x^2
400 = x^2
x = 
x = 20
133 adult tickets were sold.
Step-by-step explanation:
Given,
Total tickets sold for school play = 399
Let,
x represent the number of children tickets sold.
y represent the number of adult tickets sold.
According to given statement;
x+y=399 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 2 in Eqn 1

Dividing both sides by 3

133 adult tickets were sold.

Answer:
The line would be y = 6/5x + 26/5
Step-by-step explanation:
To find the equation, we first need to find the slope. We can do this by using the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (8 - -4)/(4 - -6)
m = 12/10
m = 6/5
Now that we have the slope, we can use that and either point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 8 = 6/5(x - 4)
y - 8 = 6/5x - 24/5
y = 6/5x + 26/5
The equation is -3x/y
Plug in the numbers given for x and y
-3(10)/-3.5
-30/-3.5
divide and that's your answer
Answer:
Maximum number of people is 35
Step-by-step explanation:
With a total of $160 you have to pay for the bus and all the people. The bus cost $90 so you subtract that from the 160 because you bought (or rented) the bus. Then you have $70 left to pay for everyone's tickets. If each ticket is $2 then you can buy 35 tickets in total because 70 divided by 2 = 35.
