Evaluate each expression. 7. 8 + t/5 × 10, when t = 20

• 48

• 28

• 40

• 52

Simplify each expression. 2. 20 + a + 6(8 + a)

• 20 + a + 48 + 6a = 68 + 7a

• 20 + a + 48 + 6a = 74 + 5a

• 20 + a + 6(8) + a = 68 + 2a

• 20 + a + 6a + 8 = 28 + 7a

Simplify each expression. 3. (1/8)(a + 80) + 20a

• (1/8)a + 10 + 20a = 20a + (1/8)a + 10

• (1/8)a + 80 + 20a = 20a + (1/8)a + 80

• (1/8)a + 8 + 20a = 20a + (1/8)a + 8

• (1/8)a + 20 + 20a = 20a + (1/8)a + 20

Simplify each expression. 6. 10(5 + a)

• 50 + 10a

• 10 + 5a

• 50a + 10

• 5 + 10a

Simplify each expression. 8. 4(c + 8) + 12c

• 4c + 32 + 12c = 16c + 32

• 4c + 8 + 12c = 16c + 8

• 4c + 8 + 12c = 4c + 20c

• 4c + 32 + 12c = 4c + 44c

Simplify each expression. 12. 17 + (4/5)(v - 2)

• 17 + (4/5)v - 8/5 = (4/5)v + 17 - 1.6 = (4/5)v + 15.4

• 17 + (4/5)v + 8/5 = (4/5)v + 17 + 1.6 = (4/5)v + 18.6

• 17 + (4/5)v - 2 = (4/5)v + 15

• 17 + (4/5)v - 2/5 = (4/5)v + 17 - 0.4 = (4/5)v + 16.6

Simplify each expression. 13. 3 + 15(v - 2)

• 3 + 15v - 30 = 15v - 27

• 3 + 15v - 2 = 15v + 1

• 3 + 15v - 2 = 15v + 5

• 3 + 15v - 30 = 15v - 33

Simplify each expression. 15. (3/8)(8 + t) + 4t

• 3 + (3/8)t + 4t = 3 + (35/8)t

• 3 + (3/8)t + 4t = 3 + (7/8)t

• 3 + (3/8)t + 4t = 3 + (32/8)t

• 3 + (3/8)t + 4t = 3 + (11/8)t
