Let X represent the cost of 1 pear and Y represent the cost of 1 peach.
Use the given information to set up a system of equations:
5X + 6Y = 11.20
3X = 2Y
Use the second equation to solve for Y:
3X = 2Y
Y = 1.5X
Plug the new found value for Y into the first, unused equation:
5X + 6(1.5X) = 11.20
Simplify:
5X + 9X = 11.20
or
14X = 11.20
Solve for X:
X = .8
Now that you have the value for X, you can plug it into either of the first two equations to solve for Y:
3X = 2Y
3(.8) = 2Y
2.4 = 2Y
Y = 1.2
Each pear is $0.80 and each peach is $1.20.

Answer:
the distance i believe between the points are
(1,1) , (3,3)
(7,9) , (0,3)
(1,2) , ( 3,9)
Step-by-step explanation:
Ax+by=c
First you'll find the equation of the graphed line in slope-intercept form, y = mx+b, and then from there we'll convert it into standard form, ax+by = c.
Answer:
solution set={35/3}
<u>Step-by-step explanation:</u>
--3(x+5)=50
- opening brackets to simplify
3x+15=50
- subtracting 15 on both sides to find the value of x
3x+15-15=50-15
3x=35
- dividing 3 on both sides to find the value of x
3x/3=35/3
x=35/3=11.66
solution set={35/3}
hope it will help ^_^
