Answer:

<h2>3.14159</h2>

Step-by-step explanation:

A) Pi value using circumferences

C = circumference

d= diameter

Formula: C = Pi*d⇒Pi = C/d

Circle A)

Pi = 21.98/7 = 3.14

Circle B)

Pi = 18.84/6= 3.14

B) Using areas

A = area

r = radio = diameter/2

Formula: A = Pi*(r^2 )⇒ Pi = A/(r^2)

Circle A

Pi = 38.465/(3.5)^2= 3.14

Circle B

Pi= 28.26/(3^2)= 3.14

6x - 2y = 26<br><br> 2x + 3y = 5<br><br> Solve for X and Y
Softa [21]

Answer:

y is equal to -1

x is equal to 4

Step-by-step explanation:

The first thing you would do is multiply the bottom equation by a negative 3. You will get - 6x - 9y = -15. Keep the top equation the same. Both of the 6x's cancel. You then get -11y = 11 so y is equal to negative 1.

Since you have Y, you can now plug that in to any equation to find the value of x. -6x - 2(-1) = 26. You're left with 4. Plug both of the values into each equation to double check.

Solve1 over 25 = 5^x ^+ 4. <br> x = -7/2<br> x = −6 <br> x = 9/2 <br> x = 2
Basile [38]
The equation seems to be

   1
-------- = 5 ^ (x + 4)
  25

In that case, this is the solution, stept by step:

1) factor 25: 25 = 5^2

          1
=> ----------- = 5^(x + 4)
         5^2

2) invert 5^2

=> 5^(-2) = 5^(x+4)

3) Given that the bases are equal, the exponents also have to be equal:

=> - 2 = x + 4

3) transpose +4:

=> - 2 - 4 = x

=> x = - 6

Answer: - 6
