39×5=n×15

or,39×5/15=n

or,195/15=n

or,n=13

Jesse bought 10 more pencils than erasers. A pencil costs $0.15 and an eraser costs $0.22. He paid a total of $4.46. How many er
VARVARA [1.3K]

“Jesse bought 10 more pencils than erasers”       means    P = 10 + E

 “A pencil costs $0.15”   means that     $0.15*P was spent on pencils

 “an eraser costs $.22”    means that    $0.22*E was spent on erasers

 “He paid a total of $4.46”    means that   $0.15*P + $0.22*E = $4.46

15*(10+E)   +   22*E    =   446

                       150 + 37E = 446

                          37E = 296

                              E = 8   Jesse bought 8 erasers

(y-5)/2=(y+6)/3 solve
MA_775_DIABLO [31]

The solution of the given equation represented in the task content can be determined by first evaluating the LCM and hence is; y= 27.

<h3>What is the solution of the equation as given in the task?</h3>

The given equation is; (y-5)/2=(y+6)/3.

Hence, by multiplying the equation by 6, we have;

3(y-5) = 2(y+6)

3y -15 = 2y +12

y = 27.

Hence, it follows that the value of y which is a solution to the equation is; y = 27.
