W=x
L=2x+17

Double everything since we need to lengths and two widths to find the perimeter

2x+17+2x+17+x+x = 76
Combine like terms

6x+34=76
Solve for x
First step is subtract 34 from both sides

6x=42
Next you divide both sides by 6 in order to get x by itself

X=7

Now you plug in 7 into the x’s in length and width

W=7 cm
L=31 cm

THE WIDTH IS 31 CM

Check:

7+7+31+31 = 76 cm
It equals 76 cm just like the problem said so therefore it is right.

A. Find x. The figure is not drawn to scale.
riadik2000 [5.3K]

Step-by-step explanation:

a) The circumference of a circle is 360 degrees. so:

7x+15+8x+6x+30=360

21x+45=315

21x=135

x=<u>15</u>

b) This means 7(15)+15=120, 8(15)=120, and 6(15)+30=120. Thus, by the inscribed angle theorem, all the angles measure 60 degrees, and the triangle is thus <u>equilateral</u> and <u>isosceles</u>.

A bonsai tree is 18 inches wide and stands 2 feet tall. What is the ratio of the width of the bonsai to its height?
Afina-wow [57]

Answer:

3:4

Step-by-step explanation:

Before we start to deal with the ratio, we need all lengths in the same units.

The width is 18 inches.

The height is 2 feet.

Let's convert the height to inches. Then we will have both dimensions in the same units, inches.

2 ft * (12 in.)/ft = 24 in.

Now we have:

width = 18 in.

height = 24 in.

ratio of width to height = 18 in. to 24 in. = 18/24 = 3/4 = 3:4
