2 answers:

8 0

There are several information's already given in the question. Based on those information's, the answer can be easily deduced.
The equation given in the question is
x = 0.8x + 72
x - 0.8x = 72
0.2x = 72
x = 360
Now
Number of people that became
member of the site = (80/100) * 360
= 288 people
From the above deduction, it can concluded that the correct option among all the options that are given in the question is 288.

Answer:

$\frac{1}{2}$ which agrees with answer B

Step-by-step explanation:

First write the equation that represents this type of variation:

$y=\frac{5}{x}$

then we need to solve for "x" when y = 10 as shown below:

$y=\frac{5}{x} \\10=\frac{5}{x} \\10*x=5\\x=\frac{5}{10} \\x=\frac{1}{2}$

a friend is having trouble with exponents and asks you to review some worked probelems look over the problems and correct any mi

Stella [2.4K]

We have the following expression:

$2x^2y\cdot3x^5y^2$

By combining similar terms, we get

$2\cdot3\cdot x^2\cdot x^5\cdot y\cdot y^2$

now, 2 times 3 is 6 and to add exponents, both the exponents and variables should be alike:

$x^2\cdot x^5=x^{2+5}=x^7$

Similarly,

$y\cdot y^2=y^{1+2}=y^3$

Therefore, the answer is

$6x^7y^3$
