Answer:

x = $\frac{ab}{a-1}$

Step-by-step explanation:

Given

a(x - b) = x ← distribute parenthesis on left side

ax - ab = x ( subtract x from both sides )

ax - x - ab = 0 ( add ab to both sides )

ax - x = ab ← factor out x from each term on the left side

x(a - 1) = ab ← divide both sides by a - 1

x = $\frac{ab}{a-1}$

For 5 taccos 2 cups cheese is needed.

So 10 taccos is 2*(5 taccos)=2*2 cups cheese =4cups

$\begin{gathered} As\text{ 5 taccos=2cup cheese} \\ 1\text{ tacco=}\frac{2}{5}\text{cup cheese} \\ As\text{5 taccos=2cup cheese} \\ 1\text{ cup cheese=}\frac{5}{2}\text{taccos} \\ So\text{ 10 tacco=10}\ast\frac{2}{5}\text{cup cheese=2}\cdot2=4\text{cups} \\ 10\text{ cup cheese =10}\ast\frac{5}{2}\text{tacco}=5\ast5=25tac\cos \end{gathered}$ $35\text{ taccos}=35\ast\frac{2}{5}=7\cdot2=14\text{ cup cheese}$ $24\text{ cup cheese=}24\ast\frac{5}{2}=12\ast5=60tac\cos$

So to convert taccos to cups of cheese multiply by 2/5 and from cups of cheese to taccos multiply by 5/2.

What is the equation of the line? Please help asap!!!! First Correct answer will get brainestttttt !!

faust18 [17]

Answer:

3y= -2x-6

Step-by-step explanation:

The two points on the line are (-3,0) and (0,-2)

so you first get the gradient;

gradient= change in y

change in x

= -2-0

0-(-3)

= -2

so the answer above is the gradient

then pick one point that you used to get the gradient with, so as for me I'll pick (-3,0) and then a general point which is always (x, y)

since you have the gradient you can easily get the equation by doing this

y-0. = -2

x-(-3). 3

then crossmultiply to get the equation of the line

3y= -2(x+3)

3y= -2x-6
