What is 3/4- (-5 1/4) =<br><br> NEED HELP ASAP

Fantom [35]

Answer:

Step-by-step explanation:

$\frac{3}{4} - (-5\frac{1}{4})$

-5 1/4 is a mixed fraction. so we convert it into improper fraction

$-5\frac{1}{4}=-\frac{5*4 +1}{4}=-\frac{21}{4}$

$\frac{3}{4} - (-\frac{21}{4})$

negative and negative becomes positive

$\frac{3}{4} +\frac{21}{4}$

Both fractions have same denominators. so we can combine the numerators

$\frac{3+21}{4}=\frac{24}{4}$

Divide the fraction

$\frac{24}{4}=6$

In an average year, the American chemical industry produces more than 9.5 million metric tons of sodium carbonate. Over half of

Phoenix [80]

Answer:

2.09 × 10¹⁰ pounds

Step-by-step explanation:

The American chemical industry produces more than 9.5 million metric tons of sodium carbonate.

in this problem we have to calculate the amount in pounds of sodium carbonate are produced annually.

so we will convert the amount of 9.5 million metric tons to pounds.

Since in 1 metric ton = 2204.62 pounds

Hence, 9,500,000 metric ton = 2204.62 × 9,500,000

= 20943890000 pounds

= 2.09 × 10¹⁰ pounds

2.09 × 10¹⁰ pounds of sodium carbonate are produced annually.

WILL MARK BRAINLIEST !!! NEED HELP

Flura [38]

Answer:

$y = -\frac{1}{3}x-2$

Step-by-step explanation:

From the table it is clear that the line is passing through the points $(0,\: -2)= (x_1, \:y_1) \: \&\: (-6, \:0)=(x_2,\:y_2)$

(There are many other points in the table and any two of them can chosen as per our convenience)

Equation of line in two point form is given as:

$\frac{y-y_1}{y_1 - y_2} = \frac {x-x_1}{x_1 - x_2} \\\\\therefore \frac{y-(-2)}{-2 - 0} = \frac {x-0}{0 - (-6)} \\\\\therefore \frac{y+2}{-2} = \frac {x}{0+6)} \\\\\therefore \frac{y+2}{-2} = \frac {x}{6)} \\\\\therefore 6(y + 2) = - 2(x)\\\therefore 6y + 12 = - 2x \\\therefore 6y = - 2x - 12\\\\\therefore y = -\frac{2}{6}x-\frac{12}{6}\\\\\huge \red {\boxed {y = -\frac{1}{3}x-2}} \\\\$
