18 = 10 + 2k

move 10 to the other side

sign changes from +10 to -10

18-10=10-10+2k

18-10= 2k

8= 2k

divide by 2 to get k by itself

8/2= 2k/2

Cross out 2 and 2 , divide by 2 and then becomes 1*1*k= k

k=8/2

Answer: k= 4

Find the length of each side of the polygon for the given perimeter
butalik [34]

Answer:

choice number 2) 10 in, 18.5 in 31.5 in

Step-by-step explanation:

we collect and evaluate the like terms.like terms means the ones that can be evaluated. like 2y and 7y are like terms. they either can be added or subtracted to get an answer . 7y-2y =5y. but you cant subtrac or add 7y  with 5 because they are not like terms.

2y +1 + 7y + 3y + 5 = 60

(2y+7y+3y)+(1+5) = 60

12y + 6 = 60

The 6 crosses the equal sign to the other side because of like terms.And becomes a minus

12y = 60 - 6

12y = 54

y = 4.5

so,

2y +1= 2 x 4.5 + 1 =10

7y = 7 x 4.5 = 31.5

3y + 5= 3 x 4.5 + 5 =18.5

Answer is 10 in, 18.5 in, 31.5 in

2.

  • 250/6 ≈ 42 and more

3.

  • 485 - 319 = 166 more people

4.

  • 14.5x + 80 > 500
  • 14.5x > 420
  • x > 420/14.5
  • x > 29

5.

  • 1.25x + 3 ≤ 28
  • 1.25x ≤ 25
  • x ≤ 25/1.25
  • x ≤ 20 miles

6.  <em>This seems a typo... 460 is likely $60</em>

  • 60x + 145 ≤ 625
  • 60x ≤ 625 - 145
  • 60x ≤ 480
