$Given : \frac{\frac{4x}{5 + x}}{\frac{6x}{x + 2}}$

$\implies \frac{4x}{5 + x}\times\frac{x + 2}{6x}$

$\implies \frac{2}{x + 5}\times\frac{x + 2}{3}$

$\implies \frac{2(x + 2)}{3(x + 5)}$

$\implies \frac{2x + 4}{3x + 15}$

$\frac{ \frac{4x}{5 + x} }{ \frac{6x}{x + 2} } \\ = \frac{4x}{5 + x } ( \frac{x + 2}{6x} )$
$= \frac{4x^{2} + 8x}{30x + {6x}^{2} } \\ = \frac{2x(2 {x} + 4) }{2x(3 {x}+ 15)} \\ = \frac{2 {x} + 4 }{3 {x} + 15}$

Solve the equation for y<br> Y minus 5 equals 1/3 (x plus 12)

Vinvika [58]

Answer:

ok so this problem you are basically just rearranging it. you're going to want y by itself.

Step-by-step explanation:

let's start with the original equation: 5-y=1/3x +12

so first you have to move the five over, so you subtract 5 from both sides. -y=1/3x+12-5

then you subtract the 5 from the twelve since they're like terms: -y=1/3x+7

and finally you have to move the negative over. when you move the negative think of it like dividing negative one from both sides, everything on the other side has to get the negative.

so we're left with y=-1/3x-7

Can you please explain and answer this question to me, (don't mind the blue dots, they are the answers of what I think, please l

I started with c, but you could’ve started with any box.

So I took the numbers in the c box (the black box in my picture) and divided to see which were multiples of two. They all were.

Then I went to a. All of a’s numbers were divisible by 7.

Then b. Two of them are divisible by 2, so that’s not the answer. None of them were divisible by 7, so there’s your answer!

Then d. Two are divisible by 7, so your rules is divisible by 2.

I hope this helps!
