Which equation can be used to represent “ three minus the difference of s number and one equals one-half of the difference of three times the same number and four”?

1 - s = s - 4 (s=2.5)

Step-by-step explanation:

If you write the equation down, you get 3-(s-1) = 3(s-4), which (when you divide each side by 3), gives you -s+1=s-4. If you add s to both sides, you get 1 = 2s - 4, and after adding 4, you get 2s = 5, and s = 2.5

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:
