Answer:
3f - 8 = number of pennies
Step-by-step explanation:
p = 3*f - 8
Let f represent the number of five dollar bills and p the number of pennies.
The expression "The number of pennies is" is equivalent to "p =";
"three times the number of five dollar bills" is equivalent to "3*f"
"eight less than three times the number of five dollar bills" is equivalent to "3*f - 8"
Then the expression is p = 3*f - 8

GCF(330, 75, 450, 225) = 15
Steps:
Prime factorization of the numbers:
330 = 2 × 3 × 5 × 11
75 = 3 × 5 × 5
450 = 2 × 3 × 3 × 5 × 5
225 = 3 × 3 × 5 × 5
GCF(330, 75, 450, 225)
= 3 × 5
= 15
