If someone helps me I’ll give brainless

Sunny_sXe [5.5K]

Answer:

128

Step-by-step explanation:

The two angles form a straight line so they add to 180

2m+62 + 3m +143 = 180

Combine like terms

5m+205=180

Subtract 205 from each side

5m+205-205=180-205

5m = -25

Divide by 5

5m/5 = -25/5

m = -5

We want to find the angle so we substitute the value of m into the the formula for the angle.

< RBM =3m +143 = 3(-5) +143 = -15+143 =128

Sistema de ecuaciones.5x+2y=-152x-2y=-6

Zolol [24]

Tnemos el sisema de ecuaciones:

$\begin{gathered} 5x+2y=-15 \\ 2x-2y=-6 \end{gathered}$

Podemos resolverlo por eliminación sumando ambas ecuaciones y eliminando y. Asi podemos resolver para x:

$\begin{gathered} (5x+2y)+(2x-2y)=(-15)+(-6) \\ 7x+0y=-21 \\ x=-\frac{21}{7} \\ x=-3 \end{gathered}$

Ahora podemos resolver para y con cualquiera de las dos ecuaciones:

$\begin{gathered} 2x-2y=-6 \\ 2\cdot(-3)-2y=-6 \\ -6-2y=-6 \\ -2y=-6+6 \\ -2y=0 \\ y=0 \end{gathered}$

Respuesta: x=-3, y=0

The frequency of a radio wave varies inversely with its wavelength. If a 100-meter wave has a frequency of 3,000 kilohertz, what

Tanzania [10]

Let the frequency be 'f' and wavelength be 'w'

$f\alpha \frac{1}{w}$

$f = \frac{k}{w}$ , $k\neq 0$

w= 100 m and f = 3,000 kilohertz

Plug in the above values to find k

3000 = $\frac{k}{100}$

To find k, multiply both side by 100

3000(100) = k

k = 300,000

So equation becomes,

$f = \frac{300,000}{w}$

w= ? f = 500 kilohertz

500 = $\frac{300,000}{w}$

w = $\frac{300,000}{500}$

w = 600 m
