Someone please help me?

EB * AE = DE *EF

x+3 *3 = 6*x-2

simplify:

3x+9 = 6x-12
subtract 3x from each side

9 = 3x -12

add 12 to each side

21 = 3x
divide both sides by 3

x = 21/3
x = 7

replace x with 7 to find EB

EB = 7+3 = 10 cm

Mike is mixing paint for his walls.He mixes 1/6 gallon blue paint and 5/8 gallon green paint in a large container.What fraction

Kaylis [27]

Answer:

$Total\ amount\ of\ paint\ mike\ mixes\ is\ \frac{19}{24}\ gallons$

Step-by-step explanation:

As given

$Mike\ is\ mixing\ paint\ for\ his\ walls.$

$He\ mixes\ \frac{1}{6}\ gallon\ blue\ paint\ and\ \frac{5}{8} \ gallon\ green\ paint\ in\ a\ large\ container.$

Thus

$Total\ amount\ of\ paint\ mike\ mixes = \frac{1}{6} + \frac{5}{8}$

L.C.M of (6,8) = 24

Than

$Total\ amount\ of\ paint\ mike\ mixes = \frac{1\times 4 + 5\times 3}{24}$

$Total\ amount\ of\ paint\ mike\ mixes = \frac{4+ 15}{24}$

$Total\ amount\ of\ paint\ mike\ mixes = \frac{19}{24}\ gallons$
