Answer:

12x = 14

simplify x=7/6

Step-by-step explanation:

(-2x+6)1/5 ║ (-8+10x)1/5

Then you'll times 1/5 to every number in the (bracts) on both sides

1/5 · (-2x) = -2/5x ║ 1/5 ·(-8) = -8/5

1/5 · (6) = 6/5 ║ 1/5 · (10x) = 10/5→ 2/1 = 2

Now you have -2/5x + 6/5 = -8/5 + 2x

Next you will subtract 6/5 from both sides and it would be

-2/5x + 2x -14/5

then you will subtract 2x from both sides and it would be

-12/5x = -14/5

Then you will multiply both sides by 5

which is 12x = 14

simplify x= 7/6

decimal x= 1.16667...

True or false

valina [46]

False because a number is rational if we can write it as a fraction where the top number of and bottom number are both whole numbers but irrational numbers is any number that is not rational. It is a number that cannot be written as a ratio of two integers(or cannot be expressed as a fraction)

What is the area of the sector with a central angle of 49° and a radius of 11 cm? Use 3.14 for pi and round your final answer to

olga_2 [115]

Answer:

$\boxed{\text{51.71 cm}^{2}}$

Step-by-step explanation:

If the angle θ is in radians, the formula for the area (A) of a sector of a circle is

A = ½r²θ

If θ is in degrees

$A = \dfrac{1}{2}r^{2}\theta \times \dfrac{\pi \text{ rad}}{180^{\circ}}= \pi r^{2}\times\dfrac{\theta }{360}$

Data:

θ = 49°

r = 11 cm

Calculation:

$\begin{array}{rcl}A& = &3.14\times 11^{2}\times\dfrac{49}{360}\\\\ & = &3.14 \times 121 \times 0.1361\\ & = & \mathbf{51.71}\\\end{array}\\\text{The area of the sector is }\boxed{\textbf{51.71 cm}^{2}}$

What is the x? please answer!

zzz [600]

Answer:

x = 2

Step-by-step explanation:

1. distribute 9 in 9(x+1)

9x + 9 = 25 + x

2. subtract x from the right side to isolate x onto one side

8x + 9 = 25

3. subtract 9 from the left side

8x = 16

4. divide both sides by 8 to get x alone

x = 2
