Answer:
n = -7
Step-by-step explanation:
-6n + 3 = 45
-3 -3
--------------------
-6n = 42
Divide both sides by -6
42/-6 = -7
n = -7
Answer:
r = -4/5
Step-by-step explanation:
Divide both sides by 15 so you have r
-12/15 simplify (both by 3)
-4/5
One way is to factor and group and get every 3
729=3 times 3 times 3 times 3 times 3 times 3
so we group the ones that happen 3 times
729=(3*3*3) times (3*3*3)
we know that we can take the cube root of each group and multiply the result
729=
![( \sqrt[3]{3*3*3})( \sqrt[3]{3*3*3})](https://tex.z-dn.net/?f=%28%20%5Csqrt%5B3%5D%7B3%2A3%2A3%7D%29%28%20%5Csqrt%5B3%5D%7B3%2A3%2A3%7D%29)
=(3)(3)=9
the answer is 9
