Answer:

On edmentum it's 360

Step-by-step explanation:

because you take 20 times 18 then that equals 360 but if you proceed, yes it's 1080 because 360 times 3 equals 1080 square centimeters.

The area of the scale drawing would be 1080 square centimeters or (1080 cm^2). I got this answer through first finding the area of the classroom in feet (which is A= lw = [18][20] = 360 ft^2) and then I proceeded to converting it to centimeters via given scale factor (3 cm = 1 foot) and had the answer of 1080 centimeters squared.

Which expression is equivalent to −1/ 12x−1 /3?
alexandr402 [8]

Answer:

\frac{1}{12} (-x-4)

Step-by-step explanation:

the expression we have is:

-\frac{1}{12} x-\frac{1}{3}

To find an equivalent expression, it would be helpful to express 1/3 so that it has a 12 in the denominator:

\frac{1}{3}=\frac{4}{12}

so we substitute this:

-\frac{1}{12} x-\frac{4}{12}

and now we have 1/12 in both terms :

-\frac{1}{12}x-\frac{1*4}{12}

so we can factor it (we take it out of each term: in the first we are left with -x and in the second with -4):

\frac{1}{12} (-x-4)

the equivalent expression is: \frac{1}{12} (-x-4)

4(2x+8)=10x+2-2x+30 what is x?
Anastaziya [24]

Let's solve your equation step-by-step.

4(2x+8)=10x+2−2x+30

Step 1: Simplify both sides of the equation.

4(2x+8)=10x+2−2x+30

(4)(2x)+(4)(8)=10x+2+−2x+30(Distribute)

8x+32=10x+2+−2x+30

8x+32=(10x+−2x)+(2+30)(Combine Like Terms)

8x+32=8x+32

8x+32=8x+32

Step 2: Subtract 8x from both sides.

8x+32−8x=8x+32−8x

32=32

Step 3: Subtract 32 from both sides.

32−32=32−32

0=0

Answer:

All real numbers are solutions.

Please Help! Thanks to whoever can answer this!
Illusion [34]
Here, we are missing the slope and the y intercept. 

Lets look for the y intercept first. 

Where does it cross the y axis?  At 3!!

3 is the y intercept. 

Now, find the slope by using the slope formula. 

m =  \frac{y2 - y1}{x2 - x1}
(0,3) and (2,1)

m = 1-3/2-0 = -2/2 = -2/2 = -1
m = -1

Okay, so we found our slope, now just write the equation. 

Answer: y = -1x + 3
