Question

to make an international telephone call, you need the code for the country you are calling. the codes for country a, country b, and c are three consecutive integers whose sum is 102. find the code for each country. countrys a code is , countrys b code is , and countrys c

Explanation:

Step1: Let the first integer be $x$.

The three consecutive integers are $x$, $x + 1$, $x+2$.

Step2: Set up the equation.

The sum of the three consecutive integers is 102, so $x+(x + 1)+(x+2)=102$.

Step3: Simplify the left - hand side of the equation.

Combining like terms, we get $3x+3 = 102$.

Step4: Solve for $x$.

Subtract 3 from both sides: $3x=102 - 3=99$. Then divide both sides by 3, so $x = 33$.

Step5: Find the other two integers.

The second integer is $x + 1=33+1 = 34$, and the third integer is $x+2=33 + 2=35$.

Answer:

Country's A code is 33, country's B code is 34, and country's C code is 35.
