Answer:
thrid one looks right
Step-by-step explanation:
<span>We will use s for the cost of a small candle and m for the cost of a medium candle.
(a)
The candles and price for Jin can be written as:
3s+1m=$3.85
The candles and price for Trish can be written as:
4s+5m=$10.45
The system of equations that we have is:
</span>3s+1m=$3.85
4s+5m=$10.45
(b)
We will use substitution to solve this problem.
From the first equation we can find out m:
3s+1m=$3.85
1m=$3.85-3s
Now we insert this into second equation and we solve it for s:
4s+5($3.85-3s)=$10.45
4s+$19.25-15s=$10.45
-11s=-8.8
s=$0.8
Now we can find m:
m=$3.85-3*$0.8
m=$3.85-$2.4
m=$1.45
(c)
The candles and price for Jin can be written as:
2s+1m=price
We can insert values for s and m:
2*$0.8+$1.45=price
price=$1.6+$1.45
price=$3.05
X= a+b+c+bx/a(x-b) but I’m not completely sure
1/3 because 4 to 12 can be written as 4/12 which can be simplified to 1/3
And 1/3 of 6 is two and if you reverse the process you would 4 into 12 three times and then find what goes into 6 three times with is 2
i think the answer is B, slope=0, y intercept= 3
