Algebra Review for Year 11 Science

Solve for x:

3x + 5 = 17

• x = 7

• x = 10

• x = 4

• x = 2

Simplify the algebraic expression:

3(2x - 4) + 2(3x + 5) =

• 12x - 10

• 5x + 3

• 10x - 12

• 6x - 8

Rearrange V=IR to make I the subject

• I = VR

• I = RV

• I = R/V

• I = V/R

• I = V-R

Solve for x:

4x - 7 = 5x + 3

• -3

• -10

• 12

• 0

Simplify the algebraic expression: 2x² + 5x - 3x² + 4

• -x² + 5x - 4

• 3x² + 5x + 4

• 2x² - 5x + 4

• -x² + 5x + 4

Rearrange to find 'v' :

E_k = (1⁄2)mv²

• v = √[2E_k ⁄ m]

• v = (2E_k) ⁄ m

• v = √[E_k ⁄ 2m]

• v = E_k ⁄ (2m)
