<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
Answer:
The answer would be 69 lol
Step-by-step explanation:
Answer:
x =11/4
Step-by-step explanation:
32(x−2)−5=19
Add 5 to each side
32(x−2)−5+4=19+5
32 (x-2) = 24
Distribute
32x -64 = 24
Add 64 to each side
32x-64+64 = 24+64
32x = 88
Divide by 32
32x/32 = 88/32
x = 88/32
Divide top and bottom by 8
x =11/4
<span>C.-8+(8+7)=(-8+8)+7.</span>
