the answers as follows

a) 16 b) 13 c) 16 d) 46 e) -630 f) 18 g) -32 h) 50 i) -6 j)38 l)61

Step-by-step explanation:

a) p + 9 = 7 + 9 = 16

b) p - s = 7 - (-4) = 7 + 4 = 13

c) r - q = 10 - (-6) = 16

d)q + 52 = -6 + 52 = 46

e) pqr = 7 X (-6) X 10 = -630

f) r + 8 = 10 + 8 = 18

g) pq + r = 7 X (-6) + 10 = -42 + 10 = -32

h) r - qs = 10 - (10 X (-4))= 10 + 40 = 50

i) 3r + 6q = 3 X 10 + 6 X (-6) = 30 - 36 = -6

j) 59 - 3p = 59 - 3 X 7 = 59 - 21 = 38

k) check your question

l) 4q + 85 = 4 x (-6) + 85 = -24 + 85 = 61

Answer:

(a) 16

(b) 11

(c) 16

(d) 46

(e) 17

(f) 18

(g) -32

(h) -14

(i) -6

(j) 38

(k)34

(l) 61

Step-by-step explanation:

(a) p+9= 7+9=16

(b) p-s = 7-(-4)=7+4=11

(c) r-q = 10-(-6) =10+6 =16

(d) q+52 = -6+52 =46

(e) p+r = 7+10 = 17

(f) r+8 = 10+8 =18

(g) pq+r =7(-6)+10 = -42+10 = -32

(h) r-qs = 10-[(-6)(-4)] = 10-(+24) = 10-24 = -14

(i) 3r+6q = 3(10) +6(-6) = 30-36 = -6

(j) 59 - 3p = 59 - 3(7) = 59-21 =38

(k) 35-1 = 34

(l) 4q+85 = 4(-6)+85 = -24+85 = 61
