Answer:
The lemonade costs 1.4.
Step-by-step explanation:
This question is solved using a system of equations.
I am going to say that:
x is the cost of a cookie.
y is the cost of a lemonade.
Total cost for cookie and lemonade is 1.80.
This means that
.
As we want y, we have that ![x = 1.8 - y](https://tex.z-dn.net/?f=x%20%3D%201.8%20-%20y)
Lemonade costs 1.00 more than the cookie?
This means that:
![y = x + 1](https://tex.z-dn.net/?f=y%20%3D%20x%20%2B%201)
So
![y = 1.8 - y + 1](https://tex.z-dn.net/?f=y%20%3D%201.8%20-%20y%20%2B%201)
![2y = 2.8](https://tex.z-dn.net/?f=2y%20%3D%202.8)
![y = \frac{2.8}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2.8%7D%7B2%7D)
![y = 1.4](https://tex.z-dn.net/?f=y%20%3D%201.4)
The lemonade costs 1.4.
1.3 times 10 is 13 and 13 to the 15th power is 51185893014090760
Answer:
length is 20 and the width is 5
Step-by-step explanation:
so Area is 100
Area = width * length
legth = 4 * width
This means:
Area = width * 4 width => Area = 5 * width
We know that area is 100 so:
100 = 5 * width
that means width = 20, but wait didn't I say that the length is 20? Yes, remember we said length = 4 * width at the beginning, so <u>length = 20</u>.
Now we can easily calculate width as width is 4 times smaller than length, so:
<u>width = 20/4 => 5</u>
We can also test if this is correct by simply using the formula to calculate rectangle. So 5 * 20 = 100, correct!
