If a gas tank can hold 30 gallons, how many gallons does it contain when it is three-fifths full?

dalvyx [7]

Answer:

3/5 of 30 = (3/5)*30

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/5

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/5

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18So when the tank is 3/5 full, there are 18 gallons in the tank.

Answer:

see below

Step-by-step explanation:

whenever there is negative number being squared, you need to add the brackets so that you inside the - 1 in front of the number

so this step is wrong

$\sqrt{ - 9 { }^{2} - 4(1)(20) }$

the -9 ² , you must include the brackets to include the -1 in front of the 9

so it should be

$\sqrt{( - 9) {}^{2} - 4(1)(20) }$

so you will get = 1

and then you continue with other parts of the formula and you will get real solutions

hope this helps
