you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

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!

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula
