Can someone help me with this question! 13-3/2 x =37

kaheart [24]

Answer:

13-3/2x=37

taking LCM,

13×2x/1×2x - 3/2x=37

26x-3 /2x=37

cross multiply

2x × 37=26x-3

74x=26x-3

74x-26x=-3

48x=-3

x=-3/48

x=-1/16

hope it helps you!

Explain how the Quotient of Powers Property was used to simplify this expression.

Strike441 [17]

Answer:

$\frac{5^{4}}{25} = 25$

Step-by-step explanation:

I'm not sure if you had a typographical error with this statement, "5 to the fourth power, over 25 = 52."

According to the Quotient Rule of Exponents:

$\frac{a^{m}}{a^{n}} = a^{(m-n)}$

Method 1:

In order for you apply the Quotient Rule, the base must be the same. Since 5 is a factor of 25, then you could rewrite 25 as 5². Doing so will give you the following exponential expression:

$\frac{5^{4}}{5^{2}} = 5^{(4 - 2)} = 5^{2} = 25$

Method 2:

Even if you solve the given problem manually, you'd still get the same answer:

$\frac{5^{4}}{25} = \frac{5*5*5*5}{25} = \frac{625}{25} = 25$

Both methods produced the same result, proving that the correct answer is 25.

The sum of a number times 3 and 6 equals 4

victus00 [196]

Let a number = x
therefore the sum of a number times 3 = 3x
and 6 means 3x+6 equals 4
so the equation is 3x+6=4
