Assuming that the apples are not tossed back into the bag after drawing them.
Total of 9 apples.
1st draw yell, 4/9
2nd draw yell, 3/8
3rd draw red, 5/7
4th draw red, 4/6
For this question, you would want to set up a system of equations.
Let x = Dog Food
Let y = Cat Food
5x+2y=20
x+4y=13
The next step is to eliminate a variable or do substitution. I personally find elimination easier. To eliminate the y, multiply the top equation by -2.
-10x-4y=-40
x+4y=13
The y's will cancel and you are left with:
-9x=-27
Divide by -9 on both sides and you get x=3. Now you want to take 3 and substitute it back into one of the original equations.
3+4y=13
Solve for y
4y=10
y=2.5
Plug both values into the top equation to check the values.
5(3)+2(2.5)=20
15+5=20
20=20
The answers are correct. Dog food is 3 dollars or euros and cat food is 2.50 euros.
Please mark brainiest and good luck :D
Answer:
Hey there :) The answer is 0.25 minutes.
Step-by-step explanation:
1 minute = 60 seconds
So, 15 ÷ 60 = 0.25 minutes
None of the above is the correct answer.
4(-52+2)= -208+8, which equals -200.
-200+-6=-206
