Define the variables for the situation. Then enter an equation. Jana's age plus 8 equals her sister's age.
j = Jana's age B
s = sister's age e
Enter an equation:
+

Definitions of the variables in the situation:

J = Jana's age

S = Sister's age

The Equation:

J + 8 = S

Step-by-step explanation:

Explanation:

In the equation we will use the variable J for Jana and S for Janna's sister. Since we know Jana's age plus 8 equals her sister's age, the equation will be J + 8 = S

you should at least use a calculater

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
