7.00 \cdot 10^{-7} m - 1\cdot 10^{-3} m

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:

1 nm = 10^{-9} m\\1 mm = 10^{-3} m

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

700 nm = 700 \cdot 10^{-9} m = 7.00 \cdot 10^{-7} m (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:

1 mm = 1 \cdot 10^{-3} m

so, the range of wavelength of infrared radiation is:

7.00 \cdot 10^{-7} m - 1\cdot 10^{-3} m

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.

-5 F

Step-by-step explanation:

you subtract 8 out of 3 which turns into a negavtive.

-5

Step-by-step explanation:

3 minus 8 equals -5
