Cooper will volunteer at a community food bank for two weeks. He will work 3.5 hours every day. Which equation represents the total number of hours, h
, Cooper will volunteer at the community food bank? (1 point)
Responses
h3.5 = 2
Start Fraction h over 3.5 End Fraction equals 2
3.5h = 14
3.5 h equals 14
h2 = 3.5
Start Fraction h over 2 End Fraction equals 3.5
h14 = 3.5

O ja = 13
Since Kendra's age is currently 13 years old, we know that her age is half the age of Justin. This means that Justin's age is twice Kendra's age.
To represent Justin's age using the variable "a", the correct equation would be:
2a = 13
So the answer is:
2a = 13
To find the equation that represents Justin's age, we need to set up the relationship between Kendra's age and Justin's age. Given that Kendra's age is half the age of Justin, and Kendra is 13 years old, we can express this relationship using the equation:
Kendra's age = Justin's age / 2
Substituting the given value for Kendra's age (13) into the equation, we have:
13 = Justin's age / 2
To solve for Justin's age, we can multiply both sides of the equation by 2 to isolate Justin's age:
2 * 13 = Justin's age
This simplifies to:
26 = Justin's age
So, the equation that represents Justin's age is:
ja = 13
