PLS help meeeeeeee!!!!!! will mark as BRAINLIEST

We are asked to find 7 is what percent to 30.

We will use proportions to solve our given problem.

Let us assume that 7 is n% of 30. So we can set a proportion as:

$\frac{n}{100}=\frac{7}{30}$

Let us solve for n.

$\frac{n}{100}\cdot 100=\frac{7}{30}\cdot 100$

$n=\frac{7}{3}\cdot 10$

$n=\frac{70}{3}$

$n=23.333$

Therefore, 7 is $23.333\%$ of 30.

Answer:

${7a^{5}b^{5} c\\$

Step-by-step explanation:

$\frac{28a^{8}b^{6} c^{3} }{4a^{3}bc^{2} }$

→ First look at the first term of each expression and see if they can be simplified, and they can

$\frac{7a^{8}b^{6} c^{3} }{a^{3}bc^{2} }$

→ Now look at the a terms, since a larger one is at the top, you subtract

$\frac{7a^{5}b^{6} c^{3} }{bc^{2} }$

→ Now simplify the b and c terms

${7a^{5}b^{5} c$

If f(x) = (3+x)/ (x-3),what is f(a+ 2)?

balandron [24]

To answer items such as this, we directly substitute the a + 2 to the all the x's in the function such that,
f(a + 2) = (3 + a + 2) / (a + 2 - 3)
Simplifying the function generated above,
f(a + 2) = (5 + a) / (a - 1)
