Answer:
1500
Step-by-step explanation:
The area of the regtangular floor is 360m². The floor is going to be retired with tiles having area of 240cm² . We need to find the number of times . Therefore ,
And , the number of tiles required will be ,
Hence the required answer is 1500 .
Let one of the number be x and the other be y
<span>two times the first number plus the second number is 41
</span>2x + y = 41
<span>the first number plus three times the second number is 73
x + 3y = 73
</span>2x + y = 41 --------- (1)
x + 3y = 73 --------- (2)
From (1):
2x + y = 41
y = 41 - 2x ------- sub into (2)
x + 3(41-2x) = 73
x + 123 - 6x = 73
x -6x = 73 - 123
-5x = -50
x = 10 -------- sub into (1)
2 (10) + y = 41
20 + y = 41
y = 41 - 20
y = 21
Ans: x = 10, y = 21
