Your answer is 9.042÷2.1=4.305
Answer:
6
Step-by-step explanation:
[x-2]=[4.7-2]=[2.7]=2
f(4.7)=3*2=6
Answer:
20
Step-by-step explanation:
Let Bonnie's age = b.
Clyde's age is 8 year more than Bonnie's age, so Clyde's age is
3b + 8
The product of the ages is 80, so
b(3b + 8) = 80
3b^2 + 8b = 80
3b^2 + 8b - 80 = 0
(3b + 20)(b - 4) = 0
3b + 20 = 0 or b - 4 = 0
3b = -20 or b = 4
b = -20/3 or b = 4
Discard the negative answer since an age is not a negative number.
Bonnie's age is 4.
Clyde's age is 3 * 4 + 8 = 12 + 8 = 20.
Answer: Clyde's age is 20.
