Faith and Alyssa go to the movie theater and purchase refreshments for their friends. Faith spends a total of $72.00 on 6 drinks and 9 bags of popcorn. Alyssa spends a total of $37.50 on 4 drinks and 3 bags of popcorn. Write a system of equations that can be used to find the price of one drink and the price of one bag of popcorn. Using these equations, determine and state the price of a bag of popcorn, to the nearest cent.

5x+10 is the correct one

hope this

2 2/3 hours duhh silly

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
