------------------------------------------------------
Formula
------------------------------------------------------
Circumference = πD

------------------------------------------------------
Find Diameter
------------------------------------------------------
10π = πD
D = 10            ← divide by π on both sides

------------------------------------------------------
Find Radius
------------------------------------------------------
Radius = Diameter ÷ 2
Radius = 10 ÷ 2
Radius = 5 

------------------------------------------------------
Answer: Radius = 5 units

How to solve 37=-3+5(x+6)
zavuch27 [327]
Distribute Property 5(x+6) basically means 5×x + 5×6 = 5x+30

37= -3+5x+30 (subtract 30 on both sides)

7=-3+5x (add three on both sides)

10= 5x (divide 5 on both sides)

x=2

A^2+B^3=c^2
6^2+8^2=c^2
36+16=c^2
52=c^2
Square root both sides

Rearrange y= 2(x-a)/x to make x the subject
Sidana [21]

Answer:

y = 2(x-a)/x

xy = 2x-2a

xy-2x = -2a

x(y-2) = -2a

x = (-2a)/(y-2)

Question 2 of 15. Step 1 of 1
azamat

Answer:

  A = -68.75p +2906.25

Step-by-step explanation:

We can solve for m and b using the given values of A and p.

  1600 = m·19 +b

  2150 = m·11 +b

Subtracting the second equation from the first, we have ...

  -550 = 8m

  m = -550/8 = -68.75

Substituting this into the first equation gives ...

  1600 = 19·(-68.75) +b

  b = 1600 +1306.25 = 2906.25

The desired linear equation is ...

  A = -68.75p +2906.25
