</u>
Answer:
Step-by-step explanation:
<u>System of equations</u>
Kathy sells candles for $3 and flowers for $5. Let's set the following variables:
x = number of candles Kathy sells
y = number of flowers Kathy sells
She plans to sell 200 items, thus:
x + y = 200
She also likes to earn $2,500. The equation for this condition is:
3x + 5y = 2500
The system of equations is
Answer:
(4,-1)
Step-by-step explanation:
You can solve this system of equations in a couple of different ways, but I'm going to use the elimination method. If you're solving a system of equations using elimination, you want to have one variable cancel out. In this case, we don't have to change anything because -3y and 3y will already cancel out if we add the two equations together. You can both add or subtract, but it's easiest to add in this case. The equation will be set up like this: 2x-3y=11
+ 7x+3y=25
--------------
After you add them together, you should get 9x=36, which you can solve by dividing both sides by 9. Then, you'll get x=4. This is your x-coordinate. Next, you want to get your y-coordinate, so you can substitute 4 into one of the two equations for x and solve for y. This will get you -1 for y. I'd also recommend checking your answer. Hope this was helpful! :)
The first is B, but I dont know the answer of the others questions, sorry
