Answer:
x=4/9
Step-by-step explanation:
27 ^(3x) = 81
Replace 27 with 3^3 and 81 with 3^4
3^3^(3x) = 3^4
We know that a^b^c = a^(b*c)
3^(9x) = 3^4
Since the bases are the same, the exponents are the same
9x =4
Divide each side by 9
9x/9 = 4/9
x = 4/9
Answer:
3/15 or 1/5
Step-by-step explanation:
There are 15 plants total and 3 of those plants are 21m tall, thus divide 3 by 15 to get the probability
To simplify the fraction, convert the decimal to fractional notation, by looking at the place value of the number.
Here 0.5 = 1/2.
And to convert to percentage simply multiply by 100.
Thus it would be 50 percent.
She will earn 50 dollars.
5x - 10y = -40
-10y = -40 - 5x
y = -40 - 5x / -10
