Answer:
1000%
Step-by-step explanation:
c=10d,
3c will become 3*10d=30d
d is 10 times to c which converts to 1000%
2x + 2x +2 are the integers
4x^2 + 4x^2 +8x +4 =884 (The sum of the integers squared)
8 x^2 +8x -880 = 0
x = 10
Therefore, the integers are:
20 and 22
Answer:
Correct answer is:

Step-by-step explanation:
Given that Number of bracelets with yellow beads is represented by 
Each bracelet with yellow beads is sold for $5.
Total money raised by bracelets with yellow beads = Number of bracelets sold
Money raised by sale of one such bracelet = 
Also Given that Number of bracelets with Orange beads is represented by 
Each bracelet with orange beads is sold for $6.
Total money raised by bracelets with orange beads = Number of bracelets sold
Money raised by sale of one such bracelet = 
Given that total money raised by sale of both type of bracelets is $660.
so, the first equation becomes:

It is also given that "<em>The number of bracelets with yellow beads that Sierra sold is 8 more than twice the number of bracelets with orange beads</em>"

So, by equation (1) and (2), the system of equations is:

Answer:
854
Step-by-step explanation:
