Isolate the y

add 7 to both sides

y - 7 = 21

y - 7 (+7) = 21 (+7)

y = 21 + 7

y = 28

28 is your answer

hope this helps

Determine the value of pie for a circle with a diameter of 9 inches and a circumference of 28.26 inches

jarptica [38.1K]

Hello from MrBillDoesMath!

Answer:

3.14

Discussion:

C = circumference, r = radius, d = diameter = 2 r

For a circle, C = 2 Pi r = d Pi

Substituting the values in the question gives

C = d Pi

28.26 = 9 Pi => divide both sides by 9

Pi = 28.26/9 = 3.14

Thank you,

the width of a piece of rectangular land is 5m shorter rhan 1/3 of its length .find the width of the land if the length is 60m,1

aniked [119]

Answer:

If width = 60 m, length = 195 m.

If width = 150 m, length = 465 m.

Step-by-step explanation:

The area of a rectangle is l * w or length times width.

So we can set an equation (letting w = width and x = length)

w = $1/3x - 5$

Part 1: width = 60m:

60 = $1/3x - 5$

65 = $1/3x$

x = 195 m

Part 2: width = 150 m:

150 = $1/3x - 5$

155 = $1/3x$

x = 465 m
