Answer:

The circumference of a circle with radius 13.8 is 86.71

Step-by-step explanation:

Circumference of a cicle in terms of radius:

Circumference = 2·π·r = 2·3.14·13.8 = 86.71

In terms of diameter:

Circumference = π·d = 3.14·27.6 = 86.66

In terms of area:

Circumference C = √4·π·A = √4·π·598.3 = 86.71

Help me plz 8th grade math need answers quick
mixer [17]

Answer:

25. Not a solution

26. Yes a solution

27. y= 2/3 x

28. y=3x+16

Step-by-step explanation:

25. The solution to a linear equation is the point (x,y). To find if an (x,y) is a solution, substitute it into the equation and see if it works.

y=4x-4 and (8,3)

3=4(8)-4

3=32-4

3=28

False

Not a solution.

26. Repeat 25 to solve 26 with y=5x-5 and (0,-5)

y=5x-5 and (0,-5)

-5=5(0)-5

-5=0-5

-5=-5

True

Yes a solution.

27. This line crosses through the origin is proportional and therefore has the form y=mx. It also has a gentle slant meaning that is less than 1/2 and goes in a positive direction. This means it is y=2/3 x.

28. Use inverse operations to rearrange the equation.

y-3x=16

y=16+3x

y=3x+16
