Answer:
a. L = 20t
Step-by-step explanation:
The length increases by 20 millimeters per minute
Keywords:
<em>Medium sodas, buy, dollars, divide
</em>
For this case we must find the amount of medium sodas that Natalie's group can buy, taking into account that they have 20 dollars and that each medium soda costs 1.25 dollars. To solve, we must divide:
Let "x" be the number of medium sodas you can buy, then:

So, Natalie's group can buy 16 medium sodas with 20 dollars
Answer:
16 medium sodas
The equation factored would be (x+7)(x-2). As 7-2=5 and (7)(2)=14.
Answer: 4/2
Step-by-step explanation: Rise over run. From point S to R it goes up 4 and over 2.
Check the picture below.
since the vertical distance, namely the y-coordinate, is twice as much as the horizontal, then if the horizontal is "x", the vertical one must be 2x.
let's find the hypotenuse first.
