Equivalent expressions are expressions that have the same value

The equivalent expression of \frac{10x^6y^{12}}{-5x^{-2}y^{-6}} is -2x^{8}y^{18}

The expression is given as:

\frac{10x^6y^{12}}{-5x^{-2}y^{-6}}

Divide the common terms in the above expression

\frac{10x^6y^{12}}{-5x^{-2}y^{-6}} = -\frac{2x^6y^{12}}{x^{-2}y^{-6}}

Combine expression with the same base, by applying the law of indices

\frac{10x^6y^{12}}{-5x^{-2}y^{-6}} = -2x^{6--2}y^{12--6}

Rewrite the exponents as follows

\frac{10x^6y^{12}}{-5x^{-2}y^{-6}} = -2x^{6+2}y^{12+6}

Evaluate the exponents

\frac{10x^6y^{12}}{-5x^{-2}y^{-6}} = -2x^{8}y^{18}

Hence, the equivalent expression of \frac{10x^6y^{12}}{-5x^{-2}y^{-6}} is -2x^{8}y^{18}

X divided by 8=1.5 divided by 2<br><br> solve for "x"
Travka [436]
1. 1,5 divided by 2 is 0,75 so on the right side its 0,75

2. We make x/8 = 0,75 | *8

so we get: x = 0,75 * 8

which is the same as x = 6

so the answer is x = 6

11) Write the explicit formula
Illusion [34]

Answer:

365

Step-by-step explanation:

tn = t1 + (n - 1)(d)

t(47) = -3 + (47 - 1)(8)

t(47) = -3 + (46)(8)

t(47) = -3 + 368

t(47) = 365

5. Priya mixes 2..5 cups of water with 1/3 cup or orange juice concentrate. Diego mixes 1 2/3 cups of water with 1/4 cup or oran
Snowcat [4.5K]

Priya needs 13⅓ cups of orange juice

Diego 15 cups

Step-by-step explanation:

......................................................................................................................

Priya

......................................................................................................................

Cup of water = 2½

Cup of orange = ⅓

If 2½ cups of water requires ½ cup of orange juice concentrate

Then 100 cups of water would require x cup of orange

Representing the above statement mathematically

2½ : ⅓ = 100 : x

5/2 : 1/3 = 100 : x ------------------Convert ratio sign to division

5/2 ÷⅓ = 100/x

5/2 * 3 = 100/x

15/2 = 100/x ---------------Multiply both sides by x

15/2 * x = 100/x * x

15x/2 = 100 ------------------ Multiply both sides by 2

2 * 15x/2 = 2 * 100

15x = 200 --------------- Divide both sides by 15

x = 200/15

x = 13⅓

So, 13⅓ cups of orange is needed by Priya

......................................................................................................................

Diego

......................................................................................................................

Cup of water = 1⅔

Cup of orange = ¼

If 1⅔ cups of water requires ¼ cup of orange juice concentrate

Then 100 cups of water would require x cup of orange

Representing the above statement mathematically

1⅔:¼ = 100:x

5/3 : ¼ = 100:x

5/3 ÷¼ = 100 ÷ x

5/3 * 4/1 = 100 ÷ x

20/3 =100/x----------------------- Multiply x to both sides

20/3 * x = 100/x * x

20x/3 = 100 ------------------------ Multiply 3 to sides by 3

3 * 20x/3 = 100 * 3

20x = 300 ------------- Divide both sides by 2

20x/20 = 300/20

x = 15

So, 15 cups of orange is needed by Diego
