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.

3 ft<br> 4 ft<br> What is the length of the hypotenuse

elena-s [515]

The length of the hypotenuse is 5ft
a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2
c^2=25
sqrt c^2= sqrt 25
c=5
Therefore, the length of the hypotenuse is 5th
