a + 12 = 13
a plus Start Fraction 1 over 2 End Fraction equals 13
13a = 2
13 a equals 2
2a = 13
2 a equals 13
12a = 13
12a = 13
The equation that represents Justin's age is:
a = 2(13)
To solve this equation, we need to use the given information that Kendra's age is half the age of Justin. Kendra's age is given as 13 years. So, we need to find the equation that represents Justin's age, a.
The equation that represents Justin's age is "a + 12 = 13". This is because Kendra's age is half the age of Justin, so if we add 12 to Kendra's age, we should get Justin's age. Substituting Kendra's age (13) into the equation, we get: 13 + 12 = 25, which represents Justin's age. So, the correct equation is:
a + 12 = 13
