With two x's combine the two 15x+(-4x) making a positive 11x-24=-79 then you add 24 to -79 because you switch the sign and add to the other side making it 11x=-55 then with the x you are trying to solve for your going do the opposite of 11 TIMES x and divide both sides giving your answer of x=-5

Combine like terms. Like 15x-4x and move the -24 on the other side and the sign of it will change. So it will be 15x-4x= -79+24
11x= -55
11x/11= -55/11
Cancelation. And the answer will be
X= -5

Find the value of x (really need help with this)

qwelly [4]

Answer:

x=-7

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

40 + x+57 + 90 =180

Combine like terms

187 +x = 180

Subtract 187 from each side

187-187 +x = 180-187

x = -7

Find the area of the triangles round to the tenth. Show steps please!

amm1812

Answer:

$\large\boxed{A=89.6}$

Step-by-step explanation:

It's the right triangle. The formula of an area of a right triangle:

$A=\dfrac{leg\cdit leg}{2}$

We have:

$leg=x\\leg=16\\\text{and the angle}\ \alpha=55^o$

Use tangent:

$tangent=\dfrac{opposite}{adjacent}$

$opposite=16,\ adjacent=x$

$\tan55^o\approx1.4281$

Substitute:

$\dfrac{16}{x}=1.4281$ <em>convert the decimal to the fraction</em>

$\dfrac{16}{x}=\dfrac{14281}{10000}$ <em>cross multiply</em>

$14281x=160000$ <em>divide both sides by 14281</em>

$x=\dfrac{160000}{14281}$

$x\approx11.2$

Calculate the area:

$A=\dfrac{(16)(11.2)}{2}=89.6$
