Answer:

x = 19

Step-by-step explanation:

6x+4 + 4x - 14 = 180

10x - 10 = 180

10 X = 190

x = 19

Answer:

x = 2

Step-by-step explanation:

note that 4096 = $8^{4}$ , then

$8^{2x}$ = $8^{4}$

Since bases on both sides are equal, both 8 , then equate the exponents

2x = 4 ( divide both sides by 2 )

x = 2

A robot moving forward at a constant speed takes 2.5 hours to travel 1 kilometer. Moving forward at this same constant speed, it

Answer:

The length of the hallway is 10 m.

Step-by-step explanation:

Given:

Time taken to cover 1 km = 2.5 hours

Distance covered in 2.5 hours = 1 km

Therefore, speed of robot = $\frac{\textrm{Distance}}{\textrm{TIme}}=\frac{1}{2.5}=0.4\ km/h$

Now, speed is constant.

Now, time taken to cover the length of hallway = 90 s

Speed of the robot = 0.4 km/h

Converting 0.4 km/h to m/s, we multiply by the factor $\frac{5}{18}$ . This gives,

$0.4\times \frac{5}{18}=\frac{1}{9}\ m/s$

Now, distance of the hallway is equal to the product of speed and time. So,

Distance of hallway = Speed $\times$ Time

Distance of hallway = $\frac{1}{9}\times 90=\frac{90}{9}=10\ m$

Therefore, the length of the hallway is 10 m.

Jake started biking to the coffee shop traveling 8 mph, after some time the bike got a flat so Jake walked the rest of the way,

melisa1 [442]

Jake travel to the coffee shop by bike with speed of $8mph$ is $56mile$ and when bike got a flat so Jake walked $4mile$

How to find the speed by biking and walking ?

let $b$ = time spent biking

then $8-b$ =time spent walking

Write distance equation

$dist=speed *time$

So bike distance $+$ walk distance $=60mile$

$8b+4(8-b)=60\\8b+32-4b=60\\4b=60-32\\b=28/4\\\\b=7hrs$

Then $8-7=1 hrs$ spent walking.

For cross check the answer find that actual distance for each

$8(7)=56mi\\4(1)=4mi\\-------\\total distance=60mile$
