Question

Jennifer has 7 red marbles and blues marbles. how many marbles does she have?

Answer 1

For this case we must find the number of marbles that Jennifer has.

Let T be the variable that determines the number of total marbles that Jennifer has.

Let x be the variable that represents the number of red marbles that Jennifer has. So, $x = 7$

Let y, the variable that represents the number of marbles blues Jennifer has. So, $y = 7$

To find the value of T, we must add the variables x and y.

So, $T = x + y$

$T = x + y$

$T = 7 + 7\\T = 14$

So, Jennifer has 14 marbles.

Answer:

14 marbles
