3. Find two consecutive integers whose sum is 143.
(hint: let x-the first integer, X+1-second integer)​

Answer 1

1.
3/4 x 3600= 2700
Answer: P2700
2.
8.7/3=4.9
4.9x2=5.8
Answer: John lives 5.8 km from school
3.
x+x+1=143
2x=142
X=71
Answer: 71,72

Answer 2

1. 3600 x 25 ÷100 =900

there fore the discount price is p900

3. it means if you add to integers you get 143

so x +x+1=143

2x +1=143

2x+1-1=143_1

2x=142

2x/2 =142/2

x=71

x+1=71+1=72
