Let
x-------------> <span>the price of each cup
</span>y-------------> the price of each plate
we know that
5x+3y=28.50----------> equation 1
and
x=y-6.30--------------> equation 2
I substitute 2 in 1
5*(y-6.30)+3y=28.50---------> 5y-31.5+3y=28.5-----> 8y=60
y=7.5
x=y-6.3---------> x=7.5-6.3---------> x=1.2
the answer is
the price of each cup is $1.2
the price of each plate is $7.5
Answer:
y = -(2/3)x - 5
Step-by-step explanation:
y-int = -5
m = rise/run
m = (-5-(-3))/(0-(-3))
m = -(2/3)
therefore,
y = -(2/3)x - 5
5 or 6 pounds because there not that heavy

<span>4(r+1.9)-9r=12.2
</span><span>4r + 7.6 -9r = 12.2
-5r = 12.2 - 7.6
-5r = 4.6
r = 4.6/-5
r = - 0.92</span>
