Solve the equation 3x + 4y = 16 for x.

3x + 4y = 16  The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 4y.

3x = -4y + 16  Divide by 3.

x = -4y/3 + 16/3  Answer B.

Explanation

3x + 4y = 16

3x = 16 - 4y

3x = 4 ( 4 - y)

x = 4(4 - y)/3

X= 16 /3 - 4y/3

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:
