Mr. rifkin had 240 digital and manual cameras. after donating 82 digital cameras and 26 manual cameras, he had 3 times as many digital cameras as manual cameras left. how many digital cameras did he have first?

181 digital cameras

Step-by-step explanation:

240-82-26=132 left cameras after donating

x = number of manual cameras left.

3x= number of digital cameras left.

132/4= 33 cameras.

x=33  3x=99

99 digital cameras plus 82 digital cameras= 181 digital cameras.

I had a problem similar like this but  it said he donated 26 digital cameras and 82 manual cameras, so if your problem was like mine the answer is 125 digital cameras.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

correct answer:

b.(19,-2)
