Let the number be xy ,
xy = 10x + y. when reversed = yx = 10y + x
x = 2y ........(a)
10x + y + 10y + x = 66.........(b)
10(2y) + y + 10y + 2y = 66
20y + y + 10y + 2y = 66
33y = 66
y = 66/33
y = 2
x = 2y = 2*2 = 4
Recall the original number is xy = 42.
1) 3/40
2) 13/22
3) -1/4
4)5/12
5)-3/16
6)-3/22
7)1/10
8)8/7
9)-7/6
Answer: No. Manolo forgot to include that the opposite of squaring a number is square rooting. If you take the square root of 36, you get 6. When you square a number, you multiply it by itself, which is what Manolo did. He multiplied 6 by itself and got the answer of 36.
Step-by-step explanation: Hope this helps!
Answer:
Area of big rectangle - area of mini rectangle
56in2 - 3in2
B. 53 in2
Given :
If a number is tripled , it give same result as 28 is added to.
To Find :
We need to find that number.
Solution :
Let, the number is x.
Mathematical equation of the given scenario is :
3x = x + 28
3x - x - 28 = 0
2x - 28 = 0
x = 14
Therefore, the which give such result is 14.
