You will add 2 to both sides and subtract 3x on both sides to get x on one side and a whole number on one side. So after doing that, you should get 12 = 4x and x will equal to 3

If a wall is in a 1/4 in scale drawing is 6 in tall how tall is the actual wall

vekshin1

So 1/4
that measn that the scale wall is 6 inches while the real wall is 4 times 6=24 inches tall (logically, it would be something like 1in/4ft so it woul dbe 24 feet not 24 inches but ok)

so 1/4
6 inches scale drawing is 1/4 of real wall
6=1/4 real
multiply by 4
24=real

asnwer is 24 inches

Answer:

2/3

Step-by-step explanation:

$\frac{3}{4} n = \frac{1}{2} \\ \\ multiply \: both \: sides \: by \: \frac{4}{3} \\ \\ \frac{ \cancel4}{\cancel3} \times \frac{\cancel3}{\cancel4} n = \frac{\cancel4 \: \: \red{ \bold2}}{3} \times \frac{1}{ \cancel2} \\ \\n = \frac{2 \times 1}{3 \times 1} \\ \\ n = \frac{2}{3}$

the length of a rectangle is five times its width. if the area of the rectangle is 245 meters squared, find its perimeter

Vikentia [17]

Your answer is 84 meters.

We can call the width x, and thus the length 5x, and then we can say that 5x × x = 245, which simplifies to 5x² = 245, and then we can solve:

5x² = 245

÷ 5

x² = 49

√

x = 7

Now that we know what x is, we can find the perimeter by using it as the width, and then multiplying it by 5 to find its length. This gives us:

(7 × 2) + (5 × 7 × 2) = 14 + (35 × 2) = 14 + 70 = 84

So your answer is 84 meters.

I hope this helps!

Mauricio divided two identical rectangles into equal parts. He colored one part of each rectangle. What is true about the areas

Ivenika [448]

Answer:

Areas of the colored parts are equal

Step-by-step explanation:

Given Mauricio divided two identical rectangles into equal parts.

Now given Mauricio colored one part of each rectangle. we have to tell about the true statement of colored parts.

Two identical rectangles means the rectangle having equal areas. He divides these two into equal parts and shaded one of each part

Let area of rectangle is x $unit^{2}$

∴ Colored part area = $\frac{1}{2}xunit^{2}$ → (1)

Similarly, other rectangle area identical to above rectangle is x $unit^{2}$

∴ Colored part area = $\frac{1}{2}xunit^{2}$ → (2)

From above eq (1) and (2), we get

Areas of the colored parts are equal which is equals to $\frac{1}{2}xunit^{2}$
