Answer:

Step-by-step explanation:

396/x - 10 = -22

add 10 to each side

396/x = -12

multiply both sides by x

396 = 12x

divide both sides by 12

33 = x

What is 18/12 as a mixed number in simplest form

murzikaleks [220]

Answer: 1 1/2

You can write this as 1 & 1/2

The whole part is 1. The fractional part is 1/2

==========================================================

Explanation:

Let's say we had 18 cookies to hand out to 12 students.

How many cookies does each student get?

Using a calculator shows that 18/12 = 1.5 which means they get one whole cookie each

The leftovers is 18-12 = 6

Then notice how 6/12 = 1/2

So that's how the improper fraction 18/12 becomes the mixed number 1 & 1/2

So each student gets 1 full cookie, plus half a cookie.

------------------

Or we could do the problem like this

18/12 = (12+6)/12

18/12 = (12/12)+(6/12)

18/12 = 1 + (1/2)

18/12 = 1 & 1/2

Find an equation of the line that passes through (-5,-7) and is parallel to 5x+9y+18=0. Give answer in slope intercept form

Kipish [7]

Answer:

y = - $\frac{5}{9}$ x - $\frac{88}{9}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 5x + 9y + 18 = 0 into slope- intercept form

Subtract 5x + 18 from both sides

9y = - 5x - 18 ( divide all terms by 9 )

y = - $\frac{5}{9}$ x - 2 ← in slope- intercept form

with m = - $\frac{5}{9}$

Parallel lines have equal slopes, thus

y = - $\frac{5}{9}$ x + c ← is the partial equation

To find c substitute (- 5, - 7) into the partial equation

- 7 = $\frac{25}{9}$ + c ⇒ c = - 7 - $\frac{25}{9}$ = - $\frac{88}{9}$

y = - $\frac{5}{9}$ x - $\frac{88}{9}$ ← equation of line

Find the solution of ×\2-1/5=×\3+1/4 please help me with this

ale4655 [162]

Answer:

$x=\frac{27}{10}$

Step-by-step explanation:

Assuming that the beginning equation is $\frac{x}{2} -\frac{1}{5} =\frac{x}{3} +\frac{1}{4}$

First, we should find the common denominator of each of fractions. For all of these denominators, 60 is the smallest common denominator

$\frac{x}{2}(\frac{30}{30}) -\frac{1}{5}(\frac{12}{12}) =\frac{x}{3}(\frac{20}{20}) +\frac{1}{4} (\frac{15}{15}) \\\\\frac{30x}{60}-\frac{12}{60} =\frac{20x}{60}+\frac{15}{60}$

Now, we can multiply each side by 60, which will remove the fractions

$30x-12=20x+15$

Now we can add 12 to each side

$30x=20x+27$

Now subtract 20x from each side

$10x=27$

And lastly, divide each side by 10

$x=\frac{27}{10}$
