Answer:
(-1,3)
Step-by-step explanation:
2x-3y=9 multiply by 3 to get 6x-9y = 27
3x+5y=4 multiply by -2 to get -6x-10y= -8
Add together -19y=19, y= -1
Put y into either equation => 2x-3(-1)=9, 2x+3=9, 2x=6, x=3
Answer:
It is 67.5
Step-by-step explanation:
You will need to first turn the mixed fraction to improper fraction and you will get (45/2) divided by 1/3= (45/2)/(1/3)=135/2=67.5. So he travel 67.5
Answer:
Step-by-step explanation:
1) Function: y = 5x - 2
2) Slope: 1/2 Y-Int: 4
3) Function: y = 6
4) Slope: -4 Y-Int: 1
5) Function: y = -2x/3
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let me help out. The value of each shirt will be gotten by subtracting $47.15 from the total amount paid for the shirt and jacket. Let's say the total amount paid is $90.02
Since the jacket cost $47.15, the cost of the shirts will be:
= $90.02 - $47.15
= $42.87
We would now divide the coat if the three shirts by 3. This will be:
= $42.87 ÷ 3
= $14.29
