Question 1 of 10
TEKS ALGEasy

Solve for x:

5x + 19 = 39

A4
B0
C6
D-1
Explanation
Subtract 19 from both sides: 5x = 20. Then divide both sides by 5: x = 4.
Question 2 of 10
TEKS ALGEasy

Solve for x:

3x + 3 = 12

A2
B-2
C3
D7
Explanation
Subtract 3 from both sides: 3x = 9. Then divide both sides by 3: x = 3.
Question 3 of 10
TEKS ALGEasy

Solve for x:

4x + 19 = 67

A17
B9
C13
D12
Explanation
Subtract 19 from both sides: 4x = 48. Then divide both sides by 4: x = 12.
Question 4 of 10
TEKS PSDMedium

A product's price increased from $100 to $115. What is the percent increase?

A15%
B10%
C115%
D20%
Explanation
Percent change = (new − old) / old × 100% = (15) / 100 × 100% = 15%.
Question 5 of 10
TEKS ADVMedium

What are the solutions to the equation x² + 4x − 5 = 0?

Ax = -1 and x = 5
Bx = 2 and x = -4
Cx = 1 and x = -5
Dx = 1 and x = -3
Explanation
Factor: (x − 1)(x − -5) = 0. Setting each factor to zero gives x = 1 or x = -5.
Question 6 of 10
TEKS ADVMedium

What are the solutions to the equation x² − 3x + 2 = 0?

Ax = 3 and x = 2
Bx = 2 and x = 1
Cx = 2 and x = 3
Dx = -2 and x = -1
Explanation
Factor: (x − 2)(x − 1) = 0. Setting each factor to zero gives x = 2 or x = 1.
Question 7 of 10
TEKS ADVMedium

What are the solutions to the equation x² − 6x + 5 = 0?

Ax = 2 and x = 6
Bx = 1 and x = 5
Cx = 1 and x = 7
Dx = -1 and x = -5
Explanation
Factor: (x − 1)(x − 5) = 0. Setting each factor to zero gives x = 1 or x = 5.
Question 8 of 10
TEKS PSDMedium

A product's price increased from $250 to $287. What is the percent increase?

A10%
B15%
C20%
D114%
Explanation
Percent change = (new − old) / old × 100% = (37) / 250 × 100% = 15%.
Question 9 of 10
TEKS GEOHard Diagram

In the right triangle shown, θ is the angle opposite the side of length 9. What is sin(θ)?

40941θ
A9/40
B41/9
C9/41
D40/41
Explanation
sin(θ) = opposite/hypotenuse = 9/41 = 9/41 in simplest form.
Question 10 of 10
TEKS GEOHard Diagram

In the right triangle shown, θ is the angle opposite the side of length 8. What is sin(θ)?

15817θ
A15/17
B8/17
C8/15
D17/8
Explanation
sin(θ) = opposite/hypotenuse = 8/17 = 8/17 in simplest form.
