Answer & Explanation
// This program is written in Coral Programming Language
// Comments are used for explanatory purpose
//The next 4 lines declares 4 variables. x,y,z and temp. temp is used as a temporary variable
float x
float y
float z
float temp
x = Get next input
y = Get next input
z = Get next input
temp = x // Assign the value of x to a temporary variable. The temporary variable will be used later
// The next line prints x raise to power y
Put RaiseToPower(x,y) to output
Put "\n" to output
//The next two lines calculate and print x raise to power y raise to power z
x = RaiseToPower (x,y)
Put RaiseToPower (x,z) to output
Put "\n" to output
x = temp
//The next two lines calculate and print the absolute value of x
Put AbsoluteValue(x) to output
The next 3 lines calculate and print the square root of xy raise to power of z
x = x * y
x = SquareRoot(x)
Put RaiseToPower (x,z) to output.
// End of Program
Answer:
D 36
Step-by-step explanation:
<em>Write the information algebraically</em>
c = 3a
c + a = 48
c = children, a = adults
<em>In the second sentence (in bold), we can replace c with 3a</em>
c + a = 48 → 3a + a = 48
<em>Simplify</em>
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
<em>We can then substitute or plug in a = 12 into the original equation:</em>
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)
<h3>There are 36 children</h3>
