Helen [10]3 years ago

The picture is a bit blurry but what I saw was 8a^3+27=0

8a^3+27=0 first you move 27 to the right side of the equation

8a^3=-27 then you divide both sides by 8

a^3 = -27/8 then take the cubed root of both sides

a= -3/2

Hope that helps ;)

please help all you gotta do is match it thank you so much also if you could please explain it too thank you i would appreciate

Answer:

1/2 = 3/6

1/3 = 4/12

1/5 = 2/10

1/4 = 5/20

Step-by-step explanation:

To make equivalent fractions, you need multiply by 1. A number divided by itself is 1.

1/1 * x/x = x/x = 1

1/2 = 3/6

\frac{1}{2} * \frac{3}{3} = \frac{3}{6}

1/3 = 4/12

\frac{1}{3} * \frac{4}{4}  = \frac{4}{12}

1/5 = 2/10

\frac{1}{5} * \frac{2}{2} = \frac{2}{10}

1/4 = 5/20

\frac{1}{4}*\frac{5}{5}=\frac{5}{20}

Hope this helps :)

Have a great day!
