Answer:

$x = - \frac{11}{7}$

Step-by-step explanation:

1) Break down the problem into these 2 equations.

$x - 1 = 6x + 12$

$- (x - 1) = 6x + 12$

2) Solve the first equation. x - 1 = 6x + 12

$x = - \frac{13}{5}$

3) Solve the second equation: -( x - 1 ) = 6x + 12.

$x = - \frac{11}{7}$

4) Collect all solution.

$x = - \frac{13}{5}. - \frac{11}{7}$

5) Check solution.

When x=-\frac{13}{5}x=−513, the original equation |x-1|=6x+12∣x−1∣=6x+12 does not hold true.

When x=-\frac{13}{5}x=−513, the original equation |x-1|=6x+12∣x−1∣=6x+12 does not hold true.We will drop x=-\frac{13}{5}x=−513 from the solution set.

6) Simplify.

$x = - \frac{11}{7}$

Therefor, the answer is x = - 11/7.

A plane flying horizontally at an altitude of 3 mi and a speed of 440 mi/h passes directly over a radar station. find the rate a

Licemer1 [7]

The distance is increasing at a rate that is the speed of the plane multiplied by the cosine of the angle between its flight path and the direct line to the radar station. That cosine is 4/√(3²+4²) = 4/5, so the distance is increasing at
440 mi/h × 4/5 = 352 mi/h

Amir is sorting his stamp collection. He has made a chart of what countries the stamps are from

natulia [17]

Answer:

Step-by-step explanation:

Given that Amir is sorting his stamp collection. He has made a chart of what countries the stamps are from

He got results as

France 1/3

Morocco 5/12

Spain 1/6

To find out what fraction of Amir's stamps are from France, Morocco, or Spain, we have to simply add the three as there is common element between any two pairs

Hence answer is

$\frac{1}{3} +\frac{5}{12} +\frac{1}{6}\\ =\frac{11}{12}$
