each next element is divided on 2

Answer 2

Answer:

Answer:

Step-by-step explanation:

-164/-84=2

-41//-20.5=2

so the answer is 2

Solving equations

----------------------------------------------------

Let's solve the problem given to us today! The problem is :

$\mapsto\quad\bf{2m-12=6}$

We need to find the value of m by solving this equation.

-----------------------------------

In order to solve for m, begin by adding 12 to both sides:

$\mapsto\quad\bf{2m=18}$

Then, to get your answer, divide both sides by 2 :

$\mapsto\quad\bf{m=9}$

Therefore, m = 9.

Evaluate 2+3y when y=8

Answers

plug 8 into the equation for y and you get 2+24 or 26.

Plug 8 in for y 2+3(8) 2+24 26

Is (4, 5) a solution to 2y – 3x = -7?

Answers

Answer: no

because when (4;5) is a solution to 2y - 3x = -7

=> 2y - 3x = -7 passes through (4;5)

but when x = 4; y = 5 => 2.5 - 3.4 = -2 (unreasonable)

=> (4;5) isnt a solution

A circle has a diameter of 6 cm. What is its area?18.84 cm 2
37.68 cm 2
28.26 cm 2
9.42 cm 2

Answers

C. 28.26 cm 2

How do you calculate the diameter of a circle?

Diameter = 2 * Radius (r) Area of the circle radius. The radius of the circle calculator uses the following area of the circle formula, Area of a circle = π * r 2

What is the area of a circle with diameter 6 centimeters?

Area = π· ( d2) 2 = 3.14· ( 62) 2 = 3.14· (3) 2 = 28.27 square centimeters (*) Area = C2 4π = 18.852 4π = 355.32(4·3.14) = 355.3212.56 = 28.27 square centimeters (*)

The first formula is A=πr², or the second formula is d=2r. Now, we could solve for a,

A=1/4πd²=1/4*π*6²=28.27433cm²,

Therefore, the solution is 28.26 cm 2

Hey there, we are going to use two formula's, the first formula is A=πr², and the second formula is d=2r. Now, we can solve for a, A=1/4πd²=1/4*π*6²=28.27433cm², Therefore, the answer is 28.26 cm 2
