Answer to Ques No 1
Perimeter of the square is 4 times the side = 4*(4x-1)
Perimeter of Rectangle = 2 times length + 2 times width = 2*(2x+2) + 2*2x
Therefore,
4*(4x-1) = 2*(2x+2) +4x
16x-4= 4x+4+4x
16x-4 = 8x+4
16x-8x = 4+4
8x = 8
x = 8/8
x=1
Answer to Ques No 2
Let the number of movies be x
Total Cost at Club 1 = 25 + 7x
Total Cost at Club 2 = 12 x
Therefore,
25+7x = 12x
12x-7x=25
5x=25
x=25/5
x=5
a member must watch 4 movies for the total cost of the two clubs to be equal
Answer to Ques No 3
Let x pounds of cashews that cost $14 per pound must be mixed with 5 pounds of peanuts that cost $6.50 per pound to make mixed nuts that cost $10.25 per pound
Therefore,
14x + 5*6.50 = 10.25 (5+x)
14x + 32.50 = 52.50 + 10.25x
14x-10.25x = 52.50-32.50
3.75x = 20
x = 20/3.75
x = 5.33
5.33 pounds of cashews that cost $14 per pound must be mixed with 5 pounds of peanuts that cost $6.50 per pound to make mixed nuts that cost $10.25 per pound
