Translate each sentence into an equation. 1: one half of a number is four.2: six less than a number is nine.3: twice a number is 12 more than five times a number.4: five more than twice x is five less than x.5: eleven more than twice x is five less than x.

1. 1/2x = 4

2. x - 6 = 9

3. 2x = 5x + 12

4. 2x + 5 = x - 5

5. 2x + 11 = x - 5

Hope this helps you!

answer: x

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:
