Answer:
Dial it up : ring ring
=8:9
Step-by-step explanation:
From Dial it up= $16 per 2 gb.
ratio of gb : price
2:16
can be reduced to 1:8
this means that per each Gigabyte, you pay $8.
Ring Ring has plans of $9 per 1gb
ratio of gb to price is 1:9
And the ratio between the prices
of the companies is
Dial it up:ring ring
8:9
which means that in one company you get one gb for $8, while in the other company you get the same one gb for $9.
Answer:
![k=\frac{5}{4}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B5%7D%7B4%7D)
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have that
The line pass through the points
<em>Find the value of the constant of proportionality k</em>
For x=2/5, y=1/2
substitute
![k=\frac{y}{x}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7By%7D%7Bx%7D)
![k=\frac{1}{2}:\frac{2}{5}=\frac{5}{4}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B1%7D%7B2%7D%3A%5Cfrac%7B2%7D%7B5%7D%3D%5Cfrac%7B5%7D%7B4%7D)

Answer:
x = 13
Step-by-step explanation:
5x + 25 must equal 7x - 1, because all of the angles in the figure are right angles.
Then 5x + 25 = 7x - 1, and
25 = 2x - 1, and so 2x = 26 and x = 13
