Your uncle is 2 years older than 3 times your age. when x = 2.- a. you are x years old. write an expression to describe your uncles age. - b. you are 12 years old. how old is your uncle? there is two problems you should answer a and b

A. The equation is y = 2 + 3x  

B.  38 years

Step-by-step explanation:

A)

From the question it says; you are x years old.

Let y be your uncles age

Then since your uncle is 2 years older than 3 times your age, the mathematical interpretation of this statement is;

y  =   2  +   3x

B)

The B part of the question states:  'you are 12 years old, how old is your uncle'?

To solve this problem, we will simply the equation in question A to solve

y = 2 +  3x

From the 'A' part of the question, your uncle' age is y and your age is x, since your age is now 12, this implies x= 12 so we substitute x= 12 in the above equation

y = 2 + 3(12)

y = 2 + 36

y = 38

Therefore your uncle's age is 38 years when you are 12 years old.

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
