Complete the square to solve the equation below

frutty [35]

$x^2+x= \frac{7}{4}$

Take one-half of the coefficient of x and square it, then add it to both sides.

$x^2+x+ (\frac{1}{4}) =\frac{7}{4}+ (\frac{1}{4})$

$x^2+x+(\frac{1}{4})= 2$

$\left(x+\frac{1}{2}\right)^2=2$

$x+\frac{1}{2}=\pm \sqrt{2}$
-----------------------------------------------------------------
$x+\frac{1}{2}=- \sqrt{2}$
$x=-\frac{1}{2}- \sqrt{2}$ <=

AND

$x+\frac{1}{2}= \sqrt{2}$
$x= \sqrt{2}-\frac{1}{2}$ <=

A sidewalk along side a garden at the Conservatory is to be 11 4/9 yards long. Rectangular stone tiles that are each 2 1/18 y

alexandr1967 [171]

Step-by-step explanation:

Convert the fractions in the yards given to decimals, because then you can divide the length of the sidewalk by the length of each tile. So 2/5 is 2 divided by 5 which equals .4. And 1/8 is 1 divided by 8 which is .125.

So, the sidewalk is 14.4 yards long and each tile is 1.125 yards long.

Divide the length of the sidewalk, 14.4 yards, by the length of each tile, 1.125 yards.

Equals 13.8 tiles, rounded off to 14 tiles.

Hope this helps.

14 2/5 = 72/5

1 1/8 = 9/8

72/5 = 576/40 divide by 45/40 = 576/40 x 40/45 = 23040/1800 = 12.8 tiles

A car factory takes 6 hours to produce 60 cars. How many hours does the factory take to produce 300 cars?

Answer:

30 hours

Step-by-step explanation:

Ok, since it can make 60 cars in 6 hours we take the 300 divided by the 60 to get 5. Then, multiply the 5 by the 6 to get 30 hours.
