Pretty sure you do 7.4/360. And then times pi and the radius squared. Should come out to be 10.91354 cm^2

Answer:

x = -27

Step-by-step explanation:

See below

$- 9 = \frac{x}{3}$

Cross Multiply

$- 9 \times 3 = x \times 1 \\ - 27 = x \\ x = - 27$

Answer:

35 cm

Step-by-step explanation:

As shown in the image attached, the A large rectangle is made by joining three identical small rectangles,

The width of one small rectangle is x cm and the length of one small rectangle is 2x cm. Therefore the perimeter of the small rectangle is given as:

2(length + width) = Perimeter

2(2x + x) = 21

2(3x) = 21

6x = 21

x = 21/6 = 3.5 cm

x = 3.5 cm

From the image attached, the width of the large rectangle is 2x (x + x) and the length is 3x (2x + x). Therefore, the perimeter of the large rectangle is:

2(length + width) = Perimeter

2(3x + 2x) = Perimeter

Perimeter = 2(5x)

Perimeter = 10x

Perimeter = 10(3.5)

Perimeter = 35 cm

x/4 - 5 = -8

=> x/4 = -8 + 5

=> x/4 = -3

=> x = -3 × 4

=> x = -12

So, answer is B. –12

Answer:

Step-by-step explanation:

$3)\frac{5x}{2}+125 = 180\\\\\frac{5x}{2}=180-125\\\\\frac{5x}{2}=55\\\\ 5x = 55*2\\\\ x =\frac{55*2}{5}\\\\ x = 11*2 = 22$

4) 3x+ 42 + 90= 180

3x + 132 = 180

3x = 180 -132

3x = 48

x = 48/3

x = 16
