3x + y = 15
8x - 3y = 6

unless if u could do my questions, if not i wouldn't want to

x = 23.78

step-by-step explanation:

you need to give us more information since we can't answer

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:
