Answer:

the mistake is that to "remove" the 1/2 on the left you would have to multiply by 2 (or divide by 1/2 but no one does that)

the result would be that 2h-4 = 10 should actually be 2h-4 = 20

A street has parallel curbs 40 feet apart. A crosswalk bounded by two parallel stripes crosses the street at an angle. The lengt

andreev551 [17]

Answer:

The distance, in feet, between the strip = 12 feet.

Step-by-step explanation:

From the figure attached in relation with the question, we can deduce that crosswalk is a parallelogram where

CD/AB = CE/AE

CD = 40

CE = 50

AE = 15

Let AB = x

50x = 15 × 40

X = 12

The distance, in feet, between the strip is therefore 12 feet

Solve for x and y: Thanks for the help!

sweet-ann [11.9K]

Answer:

x = 2

y = 15

Step-by-step explanation:

As the triangle is split with a line that is parallel to the base:

$\implies x:6=6:18$

$\implies \dfrac{x}{6}=\dfrac{6}{18}$

$\implies x=\dfrac{6\cdot 6}{18}$

$\implies x=\dfrac{36}{18}$

$\implies x=2$

Similarly:

$\implies y:20=6 : (6+x)$

$\implies y:20=6:8$

$\implies \dfrac{y}{20}=\dfrac68$

$\implies y=\dfrac{6 \cdot 20}{8}$

$\implies y=\dfrac{120}{8}$

$\implies y=15$
