p=2/3

q=-1/3

r=1/6

c.

p=-1/5

q=-3/10

r=2/5

now

p-q+r=-1/5-(-3/10)+2/5

Answer:

  • a) 1 1/6
  • c) 1/2

Step-by-step explanation:

<u>The expression given:</u>

  • p - q + r

<u>Evaluate for each case:</u>

a)

<u>p = 2/3, 1 = -1/3, r = 1/6</u>

  • p - q + r =
  • 2/3 - (-1/3) + 1/6 =
  • 2/3 + 1/3 + 1/6  =
  • 1 + 1/6 =
  • 1 1/6

c)

<u>p = 1/-5, q = -3/10, r = 2/5</u>

  • p - q + r =
  • -1/5 - (-3/10) + 2/5 =
  • -2/10 + 3/10 + 4/10 =
  • 5/10 =
  • 1/2

64 ivy stems

Step-by-step explanation:

To solve this problem we can use rule of three:

Firstly we had 72 ivy stems to use in 18 centerpieces, and know we have 16 centerpieces and want to know how many ivy stems we need to use, so:

18 centerpieces -> 72 ivy stems

16 centerpieces -> X ivy stems

18/16 = 72/X

X = 16*72/18 = 64

He needs to use now 64 ivy stems to maintain the ratio.
