What number is represented by 2.55 x 10-4? 255 2,550 0.255 0.000255

What is 2x + 4x + 4 = 4(x + 4) and step by step and Highlight / circle the error

mario62 [17]

Answer:

x = 6 and the +4x is wrong

Step-by-step explanation:

2x + 4x + 4 = 4(x + 4)

6x + 4 = 4x + 16

+4x +4x <--( This part is wrong )

10x + 4 = 16

-4 -4

10x = 12

10 10

x = 1.2

Correct steps

2x + 4x + 4 = 4(x + 4)

6x + 4 = 4x + 16

-4x -4x

2x + 4 = 16

-4 -4

2x = 12

A basketball team scored 78 points in a game. The players made 6 baskets worth 1 point each and 27 baskets worth 2 points each.

Nady [450]

Answer: They made 6 three point shots.

Step-by-step explanation:

Make your equation

(((6x1)+(27x2)+(3x)=78

Simplify

(6+54+3x=78)

60+3x=78

Subtract from both sides

3x=18

Divide from both sides

x=6

The basketball team scored 6 shots worth 3 points.

I NEED HELP ASAP MISSING ASSIGNMENTS HAVE TO BE TURNED IN TOMORROW \

Part 1: Circumference of circle = $105.20$ inches & Area of circle = $880.97 inches^{2}$

Part 2: Area of circle = $3.14 ft^{2}$

Part 3: Area of square not covered by circle = $29.69inches^{2}$ .

Step-by-step explanation:

Part 1:

We have radius of circle as $16\frac{3}{4} = 16.75 inches$ . Let's find area & circumference of circle:

Circumference of circle = $2\pi r$

⇒ Circumference of circle = $2\pi r$

⇒ Circumference of circle = $2\pi r$ = $2(3.14)(16.75)$

⇒ Circumference of circle = $105.20$ inches

Area of circle = $\pi r^{2}$

⇒ Area of circle= $\pi r^{2}$

⇒Area of circle = $\pi r^{2}$ = $(3.14)(16.75)^{2}$

⇒ Area of circle = $880.97 inches^{2}$

Part 2:

Circumference of circle = $2\pi r$ = $6.28ft$

⇒ $2\pi r = 6.28$

⇒ $r = \frac{6.28}{2\pi } = \frac{6.28}{2(3.14)} = 1 ft$

Area of circle = $\pi r^{2}$

⇒Area of circle = $\pi r^{2}$ = $(3.14)(1)^{2}$

⇒ Area of circle = $3.14 ft^{2}$

Part 3:

Perimeter of square = $4a$ , a is side of square.

⇒ $4a = 47$

⇒ $a = \frac{47}{4}$

⇒ a = $11.75 inch$

Since radius of circle inscribed in square is half of side of square i.e.

$radius = \frac{a}{2}\\ radius = r = \frac{11.75}{2}$

$r = 5.875inch$

Now, Area of square not covered by circle = Area of square - area of circle

⇒ $a^{2} - \pi r^{2}$

⇒ $11.75^{2} - 3.14(5.875)^{2}$

⇒ $29.69inches^{2}$

∴ Area of square not covered by circle = $29.69inches^{2}$ .
