-8x-27=-7\left(1+2x\right)+2x

Darina [25.2K]

Answer:

$x=5$

Step-by-step explanation:

$-8x-27=-7\left(1+2x\right)+2x$

Expand:

$-8x-27=-7\times 1-7\times 2x+2x$

$-8x-27=-7-12x$

Add 27 to both sides:

$-8x-27+27=-7-12x+27$

$-8x=-12x+20$

Add 12x to both sides:

$-8x+12x=-12x+20+12x$

$4x=20$

Divide both sides by 4:

$\frac{4x}{4}=\frac{20}{4}$

$x=5$

In triangle ABC below, sinC=h/a and sinA=h/c. Which of the following combines the two sine ratios into one equation?

LenaWriter [7]

We know:

$sin(C)=\frac{h}{a}$

and

$sin(A)=\frac{h}{c}$

These expressions have an $h$ term in common. We can combine them if we can find forms of the expressions in terms of $h$ :

$h=a(sin(C))$

$h=c(sin(A))$

Now, because $h=h$ (by the reflexive property), we can write:

$a(sin(C))=c(sin(A))$

This is our answer, A.
