Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65.
Let m represent the number of magazines and b represent the number of books. Which equation models the
situation?
m + b = 47.95
m+ b = 60.55
3.95m +8.950 =47.65
8.95m +3.95b=47.65

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

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
