Answer:

\huge\boxed{x=3\dfrac{1}{5}\to x=3.2}

Step-by-step explanation:

\dfrac{8}{15}=\dfrac{x}{6}\quad|\text{cross multiply}\\\\15\cdot x=8\cdot6\\\\15x=48\qquad|\text{divide both sides by 15}\\\\\dfrac{15x}{15}=\dfrac{48}{15}\\\\x=\dfrac{48:3}{15:3}\\\\x=\dfrac{16}{5}\\\\x=3\dfrac{1}{5}\to x=3.2

I need an answer ASAP.........Fifteen of the students in a math course, which was 92% of the students registered in the course,
Marianna [84]
There is a problem with this question.
if 15 students is 92% of the class, the total class size is therefore
N=15*(100/92) = 16.3, or 16 students (to the nearest integer).

So far so good.

However, if we check back, 15 students out of 16 is 15/16*100%=93.75%, nowhere near 92%.  I have no idea where the 92% came from, and hence I doubt if there might not be a typo, by the submitting user, or the teacher.

Which equation demonstrates the distributive property?
Art [367]

The correct option of your question is D

Step-by-step explanation:

To solve the sum we need to understand the distributive property

a×(b+c) = a×b + a×c

Here,

Option D is given as

RHS = 5(3+8) [ a=5, b=3 and c=8]

=15 + 40

= LHS

It satisfies the distributive property.

You can cross check the property with the other options.

D is the correct option.
