X=2y
2x+5y=9
substitute the x=2y into the second equation
2(2y)+5y=9
multiple the 2y by 2. 4y+5y=9
combine like terms. 9y=9
divide the 9 out from both sides. y=1
plug the y back into the first equation
x=2(1)
multiply. x=2
your answer is: x=2
y=1
Y=80x+270

Hello!
You first find out how many objects there are in total
4 + 9 + 3 = 16
Then you find the probability of Liliana picking a orange
Since there are 4 oranges and 16 things to pick she has a 4/16 chance of getting an orange
Next you find the probability of Liliana picking a pear
There are 3 pears and 16 items to pick so she has a 3/16 chance
Then you add them together to find the chance of either happening
4/16 + 3/16 = 7/16
So she has a 7 out of 16 chance of getting an orange or a pear
The answer is 7/16
Hope this helps!
Answer:
30 pounds of hard candy and 30 pouonds of soft candy
Step-by-step explanation:
$2 per pound added with $4 per pound would become $3 per pound
x pounds plus 60 - x pounds will add up to 60 pounds
(multiply the top with the bottom)
2x + 4x = 3(60)
6x = 180
x = 30
60 - 30 = 30
