10 Tom found out that the temperature on Friday was 13.6˚ warmer than the temperature on Wednesday, if W represents the temperature on Wednesday, write an algebraic expression, using W, that shows the temperature on Friday.

11 W + 13.6

12 Evaluate this expression if a = 36 a - 19

13 Evaluate this expression if a = 36 a – 19 36 – 19 =17

14 Evaluate this expression if b = -36 49 - b

15 Evaluate this expression if b = 36 49 – b 49 – (-36) = 85

16 Evaluate the expression if n = 18 5 +

17

18 Evaluate the expression 5m + 9 if k is equal to 5

19 Evaluate the expression 5 x 5 + 9 25 + 9 = 34

20 Evaluate the expression if m = 3 3m – 7 5

21 Evaluate the expression if m = 3 3m – 7 5 (3 x 3 – 7) ÷ 5 (9 – 7) ÷ 5

22 Mr L. rides his bike up and down hills for 50 miles. His average speed is 10 mph. How long did it take him to ride the distance? Use the formula and find the value of T D = R x T

23 Mr L. rides his bike up and down hills for 50 miles. His average speed is 10 mph. How long did it Take him to ride the distance Use the formula and find the value of T D = R x T if D = 50 and R = 10 50 = T x 10 50 ÷ 10 = T 5 = T

24 David drives his motorcycle for 240 miles. His average speed is 30 mph. How long did it Take him to ride the distance? Use the formula and find the value of T D = R x T

25 David drives his motorcycle for 240 miles. His average speed is 30 mph. How long did it Take him to ride the distance Use the formula and find the value of T D = R x T 240 = 30 x T It will take him 8 hours

26 Kaheria and D’ana get in their car and for 360 miles. If they drive for 8 hours, what is their rate? Use the formula and find the value of T D = R x T

27 Kaheria and D’ana get in their car and for 360 miles. If they drive for 8 hours, what is their rate? Use the formula and find the value of T D = R x T 360 = R x 8 45 = R Their rate is 45 mph

28 Mr. Lebatique was riding his bike for 8 hours at 15 miles per hour. How far did he ride his bike? Use the formula R x T = D,

29 Mr. Lebatique was riding his bike for 8 hours at 15 miles per hour. How far did he ride his bike? Use the formula R x T = D 15 x 8 = 120 Mr. L rode 120 miles

30 Mr. T collected whale and dolphin cards. For every 7 whale cards she has 4 dolphin cards. If Josh has a total of 44 cards, how many dolphin cards does she have? Whale Cards Dolphin Cards Total Cards 7411

32 Find the value of p p + 25 = 40

33 Find the value of p p + 25 = 40 p + 25 - 25 = 40 - 25 p = 15

34 Find the value of h -13 = 9 + 2m

35 Find the value of h -13 = 9 + 2m - 9 -9 -13 – 9 = 2m -13 + - 9 = 2m -22 = 2m -11 = m

36 Find the value of g -5g - 14 = 36

37 Find the value of g -5g - 14 = 36 +14 +14 -5g = 50 g = -10

38 Find the value of m - m + 2.5 = 12.6

39 Find the value of m m + 2.5 = 12.6 - m + 2.5 – 2.5 = 12.6 – 2.5 - m = 10.1 m = -10.1

40 Evaluate the following expression for n 27 = -6n

41 Evaluate the following expression for n 27 = -6n 27 ÷ -6 = -6n -6 3.75 = n

42 Use the formula: R x T = D If R (rate) = 10 D (distance) = 150 Find the value of T (time)

43 Use the formula: R x T = D If R (rate) = 10 D (distance) = 150 Find the value of T (time) 10 x T = 150 T = 150 ÷ 10 T = 15

44 Solve the following expression 72 = 9m

45 Solve the following expression 72 = 9m 72 ÷ 9 = m 8 = m m = 8

46 Solve for d -8 + d = -22

47 Solve for d -8 + d = -22 +8 +8 d = -14

48 Mr. Lebatique bought a certain number of biking shirts. If Mr. Lebatique paid \$15 for each shirt. If b represents the number of biking shirts, write an expression that shows the total amount of money he spent?
