X=4. divide both sides by -1 to get 8=x+4, then subtract 4 from both sides.
This is an isosceles triangle, therefore we have two sides with the same length.
This sides are JM and MK; therefore:
JM=MK
JM=9x-18
MK=3x
Therefore:
9x-18=3x
9x-3x=18
6x=18
x=18/6
x=3
Part A:
Answer: x=3
Part B:
JM=9x-18=9(3)-18=27-18=9
Answer: JM=9
Create a line of best fit. Position your ruler in the middle of the general trend (plotted dots on a graph most likely). Draw a straight line between the dots. Make sure about half of the dots are on each side of the line. (Ten dots above the line and ten below.)
1) 1 Quarter, 2 Dimes, 2 Nickles, 10 Pennies
2) The ninth floor is 3 times as far from the ground as the third (9/3)
3) That number is 20 (20/2 = 10, 20*2 = 40, 40-10 = 30)
4) 1 Bracelet is $9 (If 2 rings are $12 then 1 ring will be $6. $36 - $18 = $18 2 bracelets = $18)
5) Addie weighs 4oz Missy weighs 14oz Corky weighs 8oz(A + M = 18, M + C = 22, A + C = 12. )
