Answer:
b
Step-by-step explanation:
$5.28 for 3 corn (divide)
the rate per corn is 1.76 ($1.76 for each corn)
the x value is the amount of corn and the y value represents the price for the amount of corn. If you multiply each x value by 1.76 only one will equal the given y value
13
x+5=3x+2
5=2x+2
3=2x
x=1.5
1.5+5=6.5
6.5 is half of DF, DF=13
your right
65/100
Divide is by 100.
a - 2.5 = 4.5
2.5 = 2.5
a = 7.0 or 7
7.0 - 2.5 = 4.5
4.5 = 4.5
