If one half of a number is 5 more than 6, what is the value when the number is tripled

Answer:

66

Step-by-step explanation:

let's use x to represent the unknown number

1/2x=5+6

solve to find x

1/2x=11

x=22

next, it asks us what is the value of the number when the number is tripled

since we already found what x is equal to, we can multiply that by 3 to figure out its value when it's tripled

3(22)=66
