Answer: Solution: (12, 3)

Step-by-step explanation:

2x - 4y = 12

3x + 4y = 48

Add both equations

5x = 60

Divide both sides by 5

x = 12

We can use the value of x to find y

3x + 4y = 48

3 (12) + 4y = 48

36 + 4y = 48

Subtract 36 from both sides

4y = 12

Divide both sides by 4

y = 3

Solution: (12, 3)

The sum of the digit of a certain two-digit number is 12. Reversing its digit increases the number by 36.find the number
Llana [10]
Hello!

You can put down all the single digits that add to 12

3 + 9 = 12
4 + 8 = 12
5 + 7 = 12
6 + 6 = 12

The possible numbers are 39, 48, 57, or 66

You flip all the numbers and find out if it goes up by 36

93 - 39 = 54

It is not 39

84 - 48 = 36

Since it went up by 36 the answer is 48

The answer is 48

Hope this helps!

When this exponent is applied to a nonzero base, the result is always 1
aleksandrvk [35]
<span>Question :Why is it that any number raised to the power zero is equal to 1 and not zero ?
<span>
Answer :</span><span>When a number is raise to the power 0, we are not actually multiplying the particular number by 0. For example, let us take 20. In this case we are not actually multiplying the number 2 by 0.

We define 20 = 1, so that each power of 2 is one factor of 2 larger than the last, e.g., 1,2,4,8,16,32...</span><span>This involves the rules of exponents particularly division. 

If a is a number and x and y are also numbers, then according to the rule of division for powers with the same base, 

a^x/a^y = a^(x - y).

It says the quotient of two powers with the same base is equal to the common base raise to the exponent equal to the difference between x and y. 

So, if x = y, then a^x/a^y = a^(x -y) = a^0 

But a^x is equal to a^y, since x = y; hence a^x/a^y = 1 

Therefore, by Transitive property of Equality, 

a^0 = 1 

Thus, this result says that number raised to the power zero is equal to 1.</span></span>
