What does the variable 'j' represent in an equation?

Back

The variable 'j' is often used to represent an unknown value that we are trying to find in an equation.

How do you solve the equation j + 26 = 47?

Back

To solve for j, subtract 26 from both sides: j = 47 - 26, so j = 21.

What is the solution of the equation 3w = 30?

Back

To find w, divide both sides by 3: w = 30 / 3, so w = 10.

Front

What does it mean when we say Sam scored four times more than Joe?

Back

It means that Sam's score is equal to 4 times Joe's score, which can be written as s = 4 * j.

How do you solve the equation y + 5 = 10?

Back

To solve for y, subtract 5 from both sides: y = 10 - 5, so y = 5.

If Quentin bought 6 new tennis balls and now has 18, how do you find how many he started with?

Back

You can set up the equation: starting amount + 6 = 18. To find the starting amount, subtract 6 from 18.

Front

What is the solution of the equation x - 4 = 10?

Back

To solve for x, add 4 to both sides: x = 10 + 4, so x = 14.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means to get the variable alone on one side of the equation to find its value.

Front

What is the equation for finding the total score if Joe scored 4 points?

Back

The equation is s = 4 * j, where s is Sam's score and j is Joe's score.
