81/4

Step-by-step explanation:

log_{3}(  \frac{4x}{{3}^{2} }   )  = 2

{3}^{2}  =  \frac{4x}{ {3 }^{2} }

9=4x/9

81=4×

x=81/4

adding logs means elements are multiplied, subtracting means divide. number in front of log is raised to power

base of log is raised to power of element after =

element in log is then equal to log base raised to power

solve resulting equation

Breann solved the system of equations below. What mistake did she make in her work?
mihalych1998 [28]
If 2x+y=5, then y=5-2x, so she substituted correctly.
x+4x=5x, so she combined like terms correctly.
She didn't subtract 10 from both sides, she added 10 to both sides.

Check the solution:
2x+y=5 \hbox{ and } x-2y=10 \\
2 \times 4-3=5 \hbox{ and } 4-2 \times (-3)=10 \\
8-3=5 \hbox{ and } 4+6=10 \\
5=5 \hbox{ and } 10=10 \\
\checkmark

The answer is: She made no mistake.

Katarina [22]

Answer:

35 times StartFraction 5 Over 7 EndFraction

Step-by-step explanation:

Alejandro has gone to school (5/7) of the last 35 days.

We need to find the expression that can be used to determine the number of days Alejandro has gone to school.

x=\dfrac{5}{7}\times 35\\\\=5\times 5\\\\=25

So, the correct option is (b) "35 times StartFraction 5 Over 7 EndFraction".
