Answer:
a = 4.762203156
Step-by-step explanation:
Given:
ab^4 = 12 and a^5b^5 = 7776
Making the equations a subject of a;
a = 12/b^4 and a^5 = 7776/b^5
Finding fifth root on both sides of equation two;
a = ![\sqrt[5]{7776}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B7776%7D)
/b
You will get a = 6/b
Equating the two equations;
12/b^4 = 6/b
Multiplying both sides by b^4 gives:
b = ![\sqrt[3]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%7D)
= 1.25992105
We had that a = 12/b^4 so;
a = 12/1.25992105^4 = 12/2.5198421 = 4.762203156
The answer is
x=9
Work: 6/54=9

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.
