Answer:

The sum of given expression \sqrt[3]{125}x^{10}y^{13}+\sqrt[3]{27}x^{10}y^{13} is  8x^{10}y^{13}

Step-by-step explanation:

 Given : expression \sqrt[3]{125}x^{10}y^{13}+\sqrt[3]{27}x^{10}y^{13}

We have find the sum of given expression \sqrt[3]{125}x^{10}y^{13}+\sqrt[3]{27}x^{10}y^{13}

Consider the given expression \sqrt[3]{125}x^{10}y^{13}+\sqrt[3]{27}x^{10}y^{13}

\sqrt[3]{125}=\sqrt[3]{5\times 5 \times 5}=\sqrt[3]{5^3}

Apply radical rule, \sqrt[n]{a^n}=a

we have, \sqrt[3]{125}=\sqrt[3]{5^3}=5

Also,  \sqrt[3]{27}=\sqrt[3]{3\times 3 \times 3}= \sqrt[3]{3^3}

Apply radical rule, \sqrt[n]{a^n}=a

we have, \sqrt[3]{27}=\sqrt[3]{3^3}=3

Thus, given expression becomes,

\sqrt[3]{125}x^{10}y^{13}+\sqrt[3]{27}x^{10}y^{13}

\Rightarrow 5x^{10}y^{13}+3x^{10}y^{13}

Simplify, we get,

\Rightarrow 8x^{10}y^{13}

Thus, the sum of given expression \sqrt[3]{125}x^{10}y^{13}+\sqrt[3]{27}x^{10}y^{13} is  8x^{10}y^{13}

Tammy bought a nightstand that was marked down 60% from an original price of $50. If she paid 10% sales tax, what was the total
AURORKA [14]

Answer: the total cost of the nightstand is $22

Step-by-step explanation:

The original price of the night stand is $50. If the original price of the night stand was marked down by 60%, it means that the amount of money by which it was reduced would be

60/100 × 50 = 0.6 × 50 = 30

The new selling price would be

50 - 30 = $20

If she paid 10% sales tax,the amount of tax paid would be

10/100 × 20 = 0.1 × 20 = 2

Therefore, the total cost of the nightstand would be

20 + 2 = $22

Graph the line giving one point and the slope. 2x-6y=12
koban [17]
Y = mx + c  

this is the equation of line and here m is the slope

so, 2x-6y =12   can be changed into standard format

y = 2x/6 - 12/6
y=x/3 +(-2)

so, m = 1/3   , so slope will be 1/3

hope it helped :)
