Answer:

Step-by-step explanation:

hello :

100^m / 1000^n

look : 100 = 10² and 1000 = 10^3

so : 100^m = (10²)^m= 10^2m and 1000^n = ( 10^3)^n = 10^3n

100^m / 1000^n = 10^2m / 10^3n

conclusion : 100^m / 1000^n = (10^(2m-3n)) when : z = 2m-3n

Total cost for cookie and lemonade is 1.80. If lemonade costs 1.00 more than the cookie, how much was the lemonade?

Ray Of Light [21]

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 $x + y = 1.8$ .

As we want y, we have that $x = 1.8 - y$

Lemonade costs 1.00 more than the cookie?

This means that:

$y = x + 1$

$y = 1.8 - y + 1$

$2y = 2.8$

$y = \frac{2.8}{2}$

$y = 1.4$

The lemonade costs 1.4.
