The answer is 7.3 or in other words 7 3/10
Hope I helped
27^(-2/3)=1/((∛27)^2)
=1/3^2
=1/9
We will see that the equation has only one solution, so the correct option is B.
<h3>
How many solutions an equation has?</h3>
For an equation of the form:
p(x) = C
Where p(x) is an expression that depends on x, and C is a constant.
The solutions are all the values of x that make the equality true.
For our case, we have:
x = -5
Notice that there is only one value of x that makes the equality true, if we replace x by -5 we get:
-5 = -5
So that is the only solution for the equation, then we conclude that the equation has only one solution, and the correct option is B.

Answer:
5, 20, 10
Step-by-step explanation:
If you were to multiply the 3 numbers using trial and error up to 5, then you'd get 5, 20, and 10, which have a combined sum of 30. You have multiplied the ratio by 5.
Answer: B
-2/5(15 - 20d + 5c)
Distribute the -2/5.
-6 + 8d - 2c
