Question

8. Evaluate the following for x = 1, y = 3, z = 10 and p = 8.
(a) x+y
(b) z-3y
(c) y + Z+2p
(d) 3p + 2x + y-z​

Answer 1

Answer:

Evaluate the following for x = 1, y = 3, z = 10 and p = 8.

(a) x+y

(b) z-3y

(c) y + Z+2p

(d) 3p + 2x + y-z

Answer 2

Answer:

a. x + y = 1 + 3 = 4

b. z - 3y = 10 - 3 x 3 = 10 - 9 = 1

c. y + z + 2p = 3 + 10 + 2 x 8 = 3 + 10 + 16 = 29

d. 3p + 2x + y - z = 3 x 8 + 2 x 1 + 3 - 10 = 24 + 2 + 3 - 10 = 29 - 10 = 19

a. 4

b. 1

c. 29

d. 19
