Select a number that can complete the equation so that it has no solution. 6(x-7/6)=6x+__

BlackZzzverrR [31]

$6(x - \frac{7}{6} ) = 6 x - 7 \\ 6x - 7 = 6x + ( - 7)$
The answer is the third option, -7.

the train traveled at an average speed of 48 miles per hour for the first 2 hours and at 60 miles an hour for the next hours. Wh

Aleksandr [31]

Answer: 56 mph

Step-by-step explanation:

48 miles x 2 hours = 96 miles

60 miles x 4 hours = 240 miles

240 + 96 = 360 total miles

360 / 6 (hours) = 56 mph

Answer:

Distance from the airport = 894.43 km

Step-by-step explanation:

Displacement and Velocity

The velocity of an object assumed as constant in time can be computed as

$\displaystyle \vec{v}=\frac{\vec{x}}{t}$

Where $\vec x$ is the displacement. Both the velocity and displacement are vectors. The displacement can be computed from the above relation as

$\displaystyle \vec{x}=\vec{v}.t$

The plane goes at 400 Km/h on a course of 120° for 2 hours. We can compute the components of the velocity as

$\displaystyle \vec{v_1}=$

$\displaystyle \vec{v_1}=\ km/h$

The displacement of the plane in 2 hours is

$\displaystyle \vec{x_1}=\vec{v_1}.t_1=.(2)$

$\displaystyle \vec{x_1}=km$

Now the plane keeps the same speed but now its course is 210° for 1 hour. The components of the velocity are

$\displaystyle \vec{v_2}=$

$\displaystyle \vec{v_2}=km/h$

The displacement in 1 hour is

$\displaystyle \vec{x_2}=\vec{v_2}.t_2=.(1)$

$\displaystyle \vec{x_2}=km$

The total displacement is the vector sum of both

$\displaystyle \vec{x_t}=\vec{x_1}+\vec{x_2}=+$

$\displaystyle \vec{x_t}=km$

$\displaystyle \vec{x_t}=$

The distance from the airport is the module of the displacement:

$\displaystyle |\vec{x_t}|=\sqrt{(-746.41)^2+492.82^2}$

$\displaystyle |\vec{x_t}|=894.43\ km$

You have $200 in a savings account. Each week for 8 weeks, you take put $18 for spending money. How much money is on your accoun

IceJOKER [234]

8 * 18 = 144

200 - 144 = 56

so $56 dollars would be left in your bank account
