Step-by-step explanation:
100/5= 20*.0075
.15 kilograms for 100 pennies
1 kilogram is 2.2 pounds
<h3>I'll teach you how to solve (81x^-20 y^-16)^-3/4</h3>
---------------------------------------------------------------
(81x^-20 y^-16)^-3/4
Apply exponents rule:
(81x^-20 y^-16)^-3/4=
1 / (81x^-20 y^-16)^-3/4
Simplify (81x^-20 y^-16)^-3/4:
1/27/x^15 y^12
Apply the fraction rule:
x^15 y^12 / 27
Your Answer Is x^15 y^12 / 27
plz mark me as brainliest if this helped :)
The first one is -4 and the second one is 6.
3(x + 8) = 2x - 9
<em><u>Distributive property.</u></em>
3x + 24 = 2x - 9
<em><u>Subtract 24 from both sides.</u></em>
3x = 2x - 33
<em><u>Subtract 2x from both sides.</u></em>
x = -33 (this is your answer)
We can plug this value into the original equation to verify if it's correct.
3(x + 8) = 2x - 9
3(-33 + 8) = 2 * -33 - 9
-75 = -75 √ this is correct
Depends on your grade in elementary, and when you decide to attend college after you graduate.
