Answer:
There are 3 adult tickets and 7 child tickets
Step-by-step explanation:
You are very close.
Let x = the number of adult tickets
Let y = number of child tickets
24.95x+ 15.95y = 186.50
The total number of tickets is 10
x+y =10
Subtract y from each side
x+y-y = 10-y
x =10-y
Substitute this into the first equation
24.95x+ 15.95y = 186.50
24.95(10-y) +15.95y = 186.50
Distribute
249.5 - 24.95y +15.95y =186.5
Combine like terms
249.5 - 9y = 186.50
Subtract 249.5 from each side
249.5-249.5 - 9y = 186.50-249.5
-9y =-63
Divide each side by -9
-9y/-9 = -63/-9
y =7
Now we need to find x
x+y =10
x+7 =10
Subtract 7 from each side
x+7-7 =10-7
x =3

|x-323|<50: answer
Step-by-step explanation :
For water to be a liquid, the temperature must be within 50 Kelvin of 323 K.
So, the range of the temperature of water will lie between 50 kelvin more than 323 kelvin and 50 kelvin less than 323.
The equation that can be used to determine the maximum temperature at which water is a liquid can be given by : x < 323 + 50
The equation that can be used to determine the minimum temperature at which water is a liquid can be given by : x > 323 - 50
So the resultant equation can be written as :
|x-323|<50
Answer: 14
The number to the right of the decimal point is either 5 or greater than that, so the 13 is increased by 1 which results in 14.
4/6, 12/15, 8/12 are some of the expressions
