How do I solve this equation?

Step-by-step explanation:

This is an inequality, not an equation.  There will be a set of x-values for which the inequality will be true.

First eliminate the fractional coefficient 2/5 by multiplying all terms by 5:

25 < 2x + 15 ≤ 75

Subtracting 15 from each 5, (2/5)x, 3 and 15 yields:

22 < 2x ≤ 60

Dividing all three terms by 2, we get:

11 < x ≤ 30

Thus, any number greater than 11 but equal to or less than 30 is a solution.

-6 is the correct option from the above given options

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
