Four friends are collecting money to buy dog food or animal for the animal shelter this food will cost $150 and each friend will collect the same amount of money

The answer is $37.50. All you do is take $150 and divide it by 4.

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
