−2(2x + 5) − 3 = −3(x − 1)

Mathematics

ZanzabumX [31]3 years ago

Answer:

x =-16

Step-by-step explanation:

-2(2x + 5) - 3 = -3(x -1)

Expand

\mathrm{Expand\:}-2\left(2x+5\right)-3:\quad -4x-13\\\\\mathrm{Expand\:}-3\left(x-1\right):\quad -3x+3\\\\-4x-13=-3x+3

Collect like terms and simplify

-4x+3x =3+13\\-x =16\\

Divide both side by -1

\frac{-x}{-1}=\frac{16}{-1}\\\\x =-16

Answer:

x=−16

Step-by-step explanation:

-2(2x+5)-3=-3(x-1)

distribute -2 into (2x+5) and -3 into (x-1)

-4x-10-3=-3x+3

combine like terms

-4x-13=-3x+3

add -4x on both sides

-13=-3x+4x+3

combine like terms

-13=x+3

subtract 3 on both sides

-16=x

hope this helps

Work out the area of the shaded region.
Makovka662 [10]

Answer: Area of the shaded region is 6.867 square cm

Step-by-step explanation:

The shaded area corresponds to the difference of the area of the rectangle and the area of the semicircle.

Area of the rectangle = 4 times 8 = 32 cm^2

Area of the semicircle = 0.5 * pi * r^2   (where r is the radius, i.e., half of the diameters, i.e., 4 cm). So Area = 0.5*pi*4^2 = 25.133 cm^2

The difference: 32 - 25.133 = 6.867 cm^2 (area of the shaded region)

Julie and her brother go to Atlanta to ride the SkyView Ferris wheel. It measures 200 feet in diameter.
worty [1.4K]

Answer:

Part A) Circumference

Part B) C=\pi D

Part C) The distance traveled in one rotation is 628.32 feet

Step-by-step explanation:

Part A) we know that

The distance around the circle is equal to the circumference.

The Ferris Wheel have a circular shape

so

To find out the distance around the Ferris Wheel you should use the circumference

Part B) What is the formula needed to solve this problem?

we know that

The circumference is equal to multiply the number π by the diameter of the circle

so

C=\pi D

Part C) What is the distance traveled in one rotation?

we know that

One rotation subtends a central angle of 360 degrees

The distance traveled in one rotation is the same that the circumference of the Ferris wheel

we have

D=200\ ft ----> diameter of the Ferris wheel

substitute in the formula of circumference

C=\pi (200)\\C=200\pi\ ft

assume

\pi=3.1416

C=200(3.1416)=628.32\ ft

therefore

The distance traveled in one rotation is 628.32 feet
