Pencils are sold in packages of 10 and erasers are sold in packages of 6 what is the least number of pencils and erasers you can buy her that there was one pencil for each eracer with none left over

The first time 6 reaches a ten is 30, which is times 5, so 5 erasers, and then easily 3 pencils, so the least amount is 5 erasers and 3 pencils :)

X= 49; x = 4step 1: foilstep 2: equal both to 0step 3: find x individually

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
