Answer:

The area of the square is 4 square cm. The area of the square and the length of its side are directional proportional quantities.

Step-by-step explanation:

A square has equal sides. We have to do length times height to get the area. 2*2 is 4. The area is 4 cm. And since this value needs to be multiplied by itself to get the area, it IS proportional.

Riley and Erik have earned a total of 135 tokens to buy items in the school store. The ratio of the number of tokens that Riley
lisabon 2012 [21]

Answer:

<em>Riley has 72 tokens</em>

Step-by-step explanation:

<u>System of Equations </u>

We have two conditions for the tokens Riley and Erik have earned. Let's call x and y to the number of tokens of Riley and Erik respectively. The first condition states that

x+y=135

Solving for y

y=135-x

The second condition is that the ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7. It's written as

\displaystyle \frac{x}{y}=\frac{8}{7}

Or equivalently

7x=8y

Replacing y from the first equation

7x=8(135-x)

Operating

7x=1080-8x

Simplifying

15x=1080

\boxed{x=72}

Riley has 72 tokens
