2 answers:

8 0

This is an EQUATION, because it has a left side, a right side, and an = sign separating the two.

An EXPRESSION does not has "sides" and no = sign.

This is an equation because it equals 5.

Expressions have no sign. For ex. 12/ (x+2). That would be simplified.

You could solve this equation too.

Given that,

Shelley's pet food store sold one customer 5 peanut butter biscuits for $3. She sold another customer 7 beef treats for $4.20.

For peanut, the cost is ratio is

$\dfrac{5}{3}$

For beef, the ratio is

$\dfrac{7}{4.2}$

If we take cross product of these items,

$\dfrac{5}{3}=\dfrac{7}{4.2}\\\\5\times 4.2=3\times 7\\\\21=21$

It implies, that the sale is in true proportion. From the cross product, we find that it is equal.
