Samuel has twenty-two fewer dimes than nickels. Samuel has a total of thirty-six nickels and dimes. How much money does he have?

Step-by-step explanation:

let n = nickels

let d = dimes

d = n - 22

n + d = 36

n + (n - 22) = 36

2n = 58

n = 29

d = 29 - 22 = 7

29($0.05) + 7($0.10) = $2.15

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

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
