<h2><u><em>
x = 2 or -3</em></u></h2>
Step-by-step explanation:
What is x in x^2-x-6=0 pls
x^2 - x - 6 = 0
x + 2 * x - 3 = 0
x + 2 = 0
x - 3 = 0
x = 2 or -3

Answer:
31.6 or 31 6/10 or 31 3/5
39.5/1.25 = 31.6
Jack gets 31.6 miles per gallon.
.25 = 1/4
.5 = 1/2
The answer to this question is the letter "A" which is $20.70. The solution is shown below:
If the guy will solely use the car, his expenses for the gasoline per month is:
Guy alone = $ 2.76/gallon * 15 gallons = $ 41.4
If the guy will let his two officemates ride the car and contribute each quarter of the of a tank:
First officemate = 15/4 * $2.76 = $ 10.35
Second officemate = 15/4 * $2.76 = $10.35
The guy total savings is shown below:
Total savings = $41.4 - $10.35 -$10.35
Total savings = $20.70
The answer is the letter "A".
Answer:
Ground speed is 61.67 km /h.
Step-by-step explanation:
Ground speed of aircraft is obtained b the sum of aircraft speed minus the current speed and direction.
For this the given formula is
81-27 cos (255 - 81 )
53.704 km/h
27 sin ( 225 - 81 ) = 2.822 km /h
so ground speed = ![\sqrt{(53.704 ^2 + 2.822)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%2853.704%20%5E2%20%2B%202.822%29%5E2%7D)
= 61.67 km /h
