Answer:

70 = 10x + 35 is your equation (10x + 35 is your expression).

3 1/2 hr is the time needed.

Step-by-step explanation:

Let hours = x.

You need 70 bookmarks, you have 35 (constant number), and you make 10 bookmarks an hour (varys).

Set the equation:

70 = 10x + 35

Solve for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First subtract, then divide.

Subtract 35 from both sides:

70 (-35) = 10x + 35 (-35)

70 - 35 = 10x

35 = 10x

Isolate the variable (x). Divide 10 from both sides:

(35)/10 = (10x)/10

x = 35/10

x = 3.5

3 1/2 hours is your answer.

The area of a circular field is 154msqu. What is the perimeter of the field?(pi=22/7) 44 49 88 176
OLga [1]

Answer:

44m

Step-by-step explanation:

A = \pir² = 154

   = 22/7 * r² = 154

   = r²  = 154 * 7/22

   = r²  = 49

   = r = √49

   = r = 7m

Perimeter of circle = 2\pir

                               = 2 * 22/7 * 7

                               = 44/7 * 7

                               = <u>44 m</u>

<u></u>
