Answer:
1 roll of ribbon, 1 package of buttons, and 3 packages of beads
Step-by-step explanation:
Use the information you found about how much each makes to answer the question.
Lynette will make 6 decorations.
Since 1 roll makes 6, she needs 1 roll.
Since 1 package of buttons makes 6, she needs 1 package.
Since 1 package of beads makes 2, she needs 3 packages.
Answer:
x=8
Step-by-step explanation:
first you need to find the unknown corner so you do 180-71= 109
then find the interior angle degree (n-2)*180 (n=number of sides) so (4-2)*180=2(180)=360
then set everything equal to 360:
10x+6+13x-2+8x-1+109=360
(combine like terms)
31x+112=360
(subtract 112 form both sides)
31x=248
(divide both sides by 31)
x=8
