x = 6

Step-by-step explanation:

It's based on similarity of triangles

DEF ~ △XYZ

$\implies \mathsf{ \frac{DE }{ XY } = \frac{EF}{YZ} = \frac{ FD}{ZX}}$

The sides should be taken in order, like the triangles start with DE and XY so, we'll proportionate DE and XY and then the next two sides and so on.

I'm using $\mathsf{ \frac{DE }{XY } = \frac{EF}{YZ} }$ to get the value of x.

[You can use any two fractions out of the three given above. ]

$\implies \mathsf{ \frac{10}{x - 1} = \frac{8}{4} }$

$\implies \mathsf{ \frac{10}{x - 1} = 2 }$

$\implies \mathsf{ 10 = 2 (x - 1) }$

$\implies \mathsf{ 10 = 2 x - 2 }$

$\implies \mathsf{ 10 + 2= 2 x }$

$\implies \mathsf{ 1 2= 2 x }$

$\implies \mathsf{ x = 6 }$

Hence, the value of x is 6.

We have 10 gallons of gas in the car. we use 1 5/8 gallons each hour. How many hours of gas do we have?

Andre45 [30]

So you have 10 gallons of gas
You use 1.625 or 1.63 an hour

You can either do 10/1.625 = 6 hours and 15 mins
You can either do 10/1.63 = 6 hours and 13 mins
