\frac{12-n}{7} = - 1
<span>Multiply cross
</span>12-n = 7*(-1)
12-n = -7
Number with incognito are to the left of the equality and numbers without incognito are to the right, remembering that when changing of side changes the signal.
-n = -7-12
-n=-19 simplify by (-1)
\boxed{n = 19}

Confirm that the solution is correct:

\frac{12-n}{7} = - 1
\frac{12-19}{7} = - 1
\frac{-7}{7} = - 1
\boxed{-1=-1}(TRUE)

Answer:
\boxed{n = 19}

[ (12 - n)/7 ] = -1

12- n = -7

-n = -19

n = 19

A countertop is 11 feet long and 4 fee t wide.
zloy xaker [14]

Answer:

4.09m^2

Step-by-step explanation:

A countertop is 11 feet long and 4 fee t wide.

Using the conversion

1foot = 0.305 meter

11fet = 11(0.305)

11feet = 3.355 m

4 feet= 4 * 0.305

4feet = 1.22m

Area of the countertop = Length * Width

Area of the countertop = 3.355 * 1.22

Area of the countertop = 4.0931m^2

Hence the required area is 4.09m^2 to 2 decimal places

Write the equation of the line that passes through the points
sesenic [268]

Answer:

y+5=2(x-3) or y+9=2(x-1)

Step-by-step explanation:

step 1

Find the slope of the line

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the ordered pairs

(3,-5) and (1,-9)

substitute the values

m=\frac{-9+5}{1-3}

m=\frac{-4}{-2}

m=2

step 2

Find the equation in point slope form

y-y1=m(x-x1)

Analyze two cases

<em>First case</em>

we have

m=2

point\ (3,-5)

substitute

y+5=2(x-3)

<em>Second case</em>

we have

m=2

point\ (1,-9)

substitute

y+9=2(x-1)

Note: The equation of the line in point slope form varies according to the point you choose, in contrast to the slope-intercept form
