A graphing calculator shows it has 3 real solutions, near x ∈ {-3.033, 1.241, 2.964}.
A unit rate is a comparison where the second value is 1. This could be miles driven per hour (one hour), the cost of one apple, the words you can type in a minute. Unit rates are helpful when trying to compare two quantities.
For this case we are going to assume that Nina wrote:
3/4 (1440) + 295.25 + (-33.50).
The expression is correct since we have:
ticket sales were three-fourths as much as yesterday. That means
3/4 (1440)
food sales were down by $ 33.50, that means:
295.25 + (-33.50)
Therefore, today's sales were:
3/4 (1440) + 295.25 + (-33.50).
answer
Nina's expression is correct
Answer:
A 24
Step-by-step explanation:
Answer:
2 kilogram bag.
Step-by-step explanation:
To figure this out, we need to divide the price by the amount of kilograms. Lets start with the 3 kilo bag. Divide 42 by 3, let y equal the price per kilo
42/3=y
Divide
14=y
Now lets do the same with the 2 kilo bag. Divide 26 by 2. Let x be this number.
26/2=x
divide
13=x
The 2 kilo bag is better as its 13 pesos per kilo compared to the 3 kilo bag's 14 pesos per kilogram.
