Problem Solving with Multiplication and Division Quick Check 1 of 51 of 5 Items Question Kendra’s age is half the age of Justin. Kendra is 13 years old. Which of the following equations represents Justin’s age, a ?(1 point) Responses 2a = 13 2 a equals 13 12a = 13 Start Fraction 1 over 2 End Fraction a equals 13 13a = 2 13 a equals 2 a + 12 = 13
The correct equation that represents Justin's age would be:
2a = 13
To solve this problem, we know that Kendra's age is half the age of Justin. Given that Kendra is 13 years old, we can set up the equation:
Kendra's age = Justin's age/2
13 = Justin's age/2
To find Justin's age, we need to multiply both sides of the equation by 2:
2 * 13 = Justin's age
Therefore, the equation that represents Justin's age is:
Justin's age = 26
So, the correct equation is: 2a = 26 (Justin's age)
To find the equation that represents Justin's age, we need to use the information given in the question. The question tells us that Kendra's age is half the age of Justin, and that Kendra is 13 years old.
Let's denote Justin's age as "a". Since Kendra's age is half of Justin's age, we can write the equation:
Kendra's age = Justin's age / 2
Substituting Kendra's age which is given as 13:
13 = a / 2
To solve for a, we can multiply both sides of the equation by 2 to get rid of the fraction:
2 * 13 = a
26 = a
So, the equation that represents Justin's age is:
a = 26
Therefore, the correct answer is "a = 26".
