1/4 = 4/16
six month improvement-> 7/16-4/16 =3/16
after another six months-> 7/16+3/16=10/16
Ans:10/16
The answer is 6y
6 times the number y is 6y
I'd set up a ratio problem
3/4 inch = 1 mile
----------- --------
1 3/4 inch x
3/4 x = 1 3/4
divide each side by 3/4 (also change 1 3/4 to improper)
you end up with
x = 7/4 x 4/3
x = 28/12
x = 7/3 or 2 1/3

Answer:
y = .25x + 50
Step-by-step explanation:
Let's use the slope-intercept equation for this problem:
y = mx + b
where m is the slope and b is the y-intercept
In this problem, m is the amount Chris pays per text and b is the flat rate.
m = price per text = .25
b = flat monthly fee = 50
Let's plug these values into the equation:
y = mx + b
y = .25x + 50
where y is the total cost for a month and x is the number of text messages
Therefore, the function is y = .25x + 50
