X=number of plates
y=number of cups

4x+5y=25.25

7x+3y=25.50

Add the two equations together:

11x+8y=50.75
11x=50.75-8y

x= $\frac{50.75-8y}{11}$

Plug x into the first equation:
4x+5y=25.25

4( $\frac{50.75-8y}{11}$ ) = 25.25

$\frac{4(50.75-8y)}{11}$ = 25.25

$\frac{203-32y}{11}$ = 25.25

203-32y = 277.75

-32y=74.75
32y=-74.45
y=2.34 (rounded to nearest hundredth)

The price of a plate is $2.34

What ratio is equivalent to 18/6

sertanlavr [38]

3/1 or just 3. The highest number divisible by the denominator (bottom number) and numerator (top number) is 6, so 18 divided by 6 is 3 and 6 divided by 6 is 1. That gives 3/1, or just write 3.
