x = 3x - 70 as corresponding angles

2x = 70

x = 35

∠LMN = 3x - 70 = 3*35 - 70 =35⁰

My parents recently moved to the Poconos, they got 30 or more inches of snow from this last snow storm. It took my Dad 2 hours t
never [62]

To determine how much will it take to clean a 120ft driveway considering that it took him 2hs to clear 10ft and that the cleaning rate is constant, you can use cross multiplication:

10ft______2hs

120ft_____xhs

If the cleaning rate is the same, then the ratios between both are the same:

\frac{2}{10}=\frac{x}{120}

From this expression, you can determine the time by multiplying both sides of the equal sign by 120

\begin{gathered} 120(\frac{2}{10})=\frac{120x}{120} \\ 24=x \end{gathered}

It will take him 24 hours to clear the 120ft driveway.

en dos líneas paralelas cortadas por una trasversal el valor de un ángulo es 2×-14 y su suplementario mide 3×-18​
ASHA 777 [7]

Responder:

x = 42,4

Explicación paso a paso:

Podemos encontrar el valor de x ya que no se nos dice qué buscar

La suma de dos ángulos suplementarios es 180 grados, por lo tanto;

2x - 14 + 3x - 18 = 180

2x + 3x - 32 = 180

5 veces = 180 + 32

5 veces = 212

x = 212/5

x = 42,4

Por tanto, el valor de x es 42,4
