It takes how many steps to solve an equation or inequality that has more than one operation?
Correct Answer
A. Two
Explanation
To solve an equation or inequality that has more than one operation, it typically takes two steps. The first step is to simplify the equation or inequality by applying the order of operations and combining like terms. This step involves performing any necessary addition, subtraction, multiplication, or division. The second step is to isolate the variable by undoing the operations in reverse order. This may involve performing addition or subtraction to move constant terms to the other side of the equation, or performing multiplication or division to cancel out coefficients. Therefore, it takes two steps to solve an equation or inequality with multiple operations.

6.
In two-step equation, simplify using the inverse of addition or .....
Correct Answer
A. Subtraction
Explanation
In a two-step equation, the goal is to isolate the variable by performing inverse operations. In this case, the correct answer is subtraction because by subtracting a number from both sides of the equation, we can eliminate it from one side and simplify the equation. This helps in isolating the variable and solving for its value.
7.
Then simplify further by using the inverse of multiplication or ....
Correct Answer
B. Division
Explanation
To simplify further by using the inverse of multiplication, we would need to divide. Division is the inverse operation of multiplication, where we divide one number by another to find the quotient. Therefore, the correct answer is division.
8.
One goal in solving an equation is to have only variables on .... side of the equal sign.
Correct Answer
A. One
Explanation
In solving an equation, the goal is to isolate the variable on one side of the equal sign. This allows us to determine the value of the variable by performing operations on the other side of the equation. Having only variables on one side simplifies the equation and makes it easier to solve.
9.
One goal in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the ....
Correct Answer
A. Equal sign
Explanation
In solving an equation, the goal is to isolate the variable on one side of the equal sign and have the numbers on the other side. The equal sign acts as the balance point, indicating that the expressions on both sides are equal. Therefore, the correct answer is "equal sign."
10.
The other goal is to have the number in front of the .... equal to one.
Correct Answer
B. Variables
Explanation
In order for the number in front of the proportion to equal one, it means that the variables in the proportion need to be balanced. Variables are quantities that can change, so having them in the equation allows for flexibility in finding the solution. On the other hand, a constant is a fixed value that does not change, and a coefficient is a number multiplied by a variable. Therefore, the presence of variables in the equation is necessary to achieve the goal of having the number in front of the proportion equal to one.
