• x < 5

• x > 5

• x = 3

Create an equation from the following statement: "The sum of twice a number and 9 is equal to 25."

• 2x + 9 = 25

• 2x - 9 = 25

• x + 9 = 25

• 2x + 9 = 34

Rearrange the formula to solve for y: 2x + 3y = 12

• y = 3

What are the steps to solve the equation: 5(x - 2) = 3x + 4?

• Distribute, combine like terms, solve for x

• Add 2 to both sides, then divide by 5

• Subtract 4 from both sides, then divide by 3

• Multiply both sides by 5, then add 2

• Yes, because it satisfies both equations

• No, because it does not satisfy y = 2x + 3

Represent the constraints of the following scenario with an inequality: "A company produces at least 100 units daily, but not more than 150 units."

• 100 = x = 150

• 100 < x < 150

What is the solution to the system of equations x + y = 10 and x - y = 2?

• x = 6

  y = 4

• x = 5

  y = 5

• x = 7

  y = 3

• x = 8

  y = 2

Model the scenario with a system of inequalities and interpret the feasible solutions: "To stay healthy, a person should consume at least 5 servings of fruits and vegetables a day, but not exceed 8 servings. If the number of fruit servings is three times the number of vegetable servings, how many servings of each can the person have?"

• Make sure the b is isolated

• Divide both sides by h

• Use the commutative property to swap the terms around the equal sign

• Multiply both sides by 2
