Justin earned $50 mowing lawns and $34 washing cars. he wants to divide his money into 3 equal accounts. how much will he put in each account? explain.

28

Step-by-step explanation:

Mowing 50

Car washing 34

Total amount 84

Now divide by 3 accounts 84/3=28

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
