Question

1 .Solve (i) 3+ 7 ( p-1) = 31 (ii) 4 ( 2-x) = 8
2 . A plane is flying at the height of 6000m above the sea level. At a particular point, it is exactly
above a submarine floating 1000 m below the sea level. What is the vertical distance between
them?

Answer 1

Step-by-step explanation:

1) 3+7p-7=31

7p-4=31

7p=35

p=5

(2) 4(2-x)=8

8-4x=8

8-4x-8=0

-4x=0

x=0
