To create algebraic expressions that represent quantities, translate the verbal description into mathematical terms following the sentence’s structure. For example, “one minus a number equals zero” becomes
1. 1 – n = 0.
Another example: John bought 25 apples and Julia bought 15. If Niccole bought twice as many as Julia, how many apples did Niccole buy?<span><span>
Steps:</span>First, restate the situation clearly so you can identify the relationship and how to form the expression.</span>
<span><span>
Solution:</span>Julia = 15 apples
Niccole = 2Julia
</span>Thus, 2Julia = 2(15) = 30 apples.
The formula for distance is d=rt. If Eddie covers 72 meters in 12 seconds, his rate is 6 meters per second.
d=rt
72=r·12
r=6
d=6t
The answer is c.
I'm sorry, I don't know the answer but wish I did.
