I'M soo not sure on this one. But if I did the math correctly your answer would be C. 64
Hoped I help!
Also sorry if its wrong.
Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as 
then the equation relating them is
c = k ← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k ×
= 8k ( divide both sides by 8 )
1.75 = k
c = 1.75 ← equation of variation
When d = 324 , then
c = 1.75 × 
= 1.75 × 18 = 31.5
$2=1 hour
$8=4 hours
She paid $6, so the amount save $8-$6=$2
2/8×100=25%
54= 3*18
54= 3*3*6
54= 3*3*3*2
33=11*3
The only shared factor is 3.
Final answer: 3
Question 3:
50-3n=5
therefore,
50-5=3n
45=3n
n=45/3
n=15
The 15th term of the sequence has a value of 5.
sorry i am not sure about the rest, i am new to this topic and have just started learning it.
