The expression that can complete the blank is 6y^3

<h3>What are expressions?</h3>

Expressions are mathematical statements that are represented by variables, coefficients and operators

<h3>How to complete the blanks?</h3>

The expression is given as

2/y^2=_/3y^5

Replace the blank with x

So, we have

2/y^2 = x/3y^5

Multiply both sides of the equation by 3y^5

So, we have

x = 3y^5 * 2/y^2

Evaluate the products

x = 6y^3

This means that the blank is 6y^3

Dakota makes a salad dressing by combining 6 1/2 fluid ounces of oil and 2 3/8 fluid ounces of vinegar in a jar. She then pours

$6 \frac{1}{2} + 2 \frac{3}{8} = \\ \frac{13}{2} + \frac{19}{8} = \\ \frac{52}{8} + \frac{19}{8} = \\ \frac{71}{8}$
$\frac{71}{8} - 2 \frac{1}{4} = \\ \frac{71}{8} - \frac{9}{4} = \\ \frac{71}{8} - \frac{18}{8} = \\ \frac{53}{8}$
$\frac{53}{8} = 6 \frac{5}{8}$

Which expression is equivalent to (2^3)^-5

Ostrovityanka [42]

Hi!

You didn't list the options, but I think I know the answer. Let me know if my answer isn't listed! :)

$(x^{3} )^{-5}$
We need to multiply the exponents.
3 · -5 = -15

The answer is $2^{-15}$

Hope this helps! :)

How can I solve this equation 5x^2-2x-6=-2x^2+9x

wel

Add 2x^2 to both sides
7x^2-2x-6=9x

Subtract 9x from both sides
7x^2-11x-6=0

Factor by using slip and slide
x^2-11x-42
(x-14)(x+3)
(x-14/7)(x+3/7)
(x-2)(7x+3)

Then use the Zero Product Property to find roots
x-2=0
x=2

7x+3=0
7x=-3
x=-3/7

Final answer: x=-3/7, x=2
