Gabe was asked to simplify the expression:`4\left(x-2\right)+\left (2x+5\right)-3x` His work is shown below.

`4\left(x-2\right)+\left(2x+5\right )-3x`

`4x-6+2x+5-3x`

`\left(4x+2x-3x\right)+\left(-6+5\r ight)`

`3x-1`

Every weekday, mr. jones bikes from his home to his job. sometimes he rides along two roads, the long route that is shown by the solid lines. other times, he takes the shortcut shown by the dashed line. how many fewer kilometers does mr. jones bike when he takes the shortcut instead of the long route?

10x − 5y + 14 = 0 whats the answer pls

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
