The sum is 61 for this equation.
Answer: he bought 12 books.
Step-by-step explanation:
Let x represent the number of books that Greg bought.
Greg ordered some books online for $6 each. This means that x books would cost $6x
He paid a total of $3 for shipping. The total cost of the purchase was $75.00. This means that
6x + 3 = 75
Subtracting 3 from the left hand side and the right hand side of the equation, it becomes
6x + 3 - 3 = 75 - 3
6x = 72
Dividing the left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 72/6
x = 12
Answer:
that could be 1/3
Step-by-step explanation:
i simplified the answer
So first, we multiply out the brackets.
-15x - 18 + 2 = 17 + 16x -1
Then, bring all the terms onto one side so you can solve.
-15x-18+2-17-16x+1=0
Then, we simplify this.
-31x-32=0
Then, isolate x
-31x=32
x=32/-31 or -1.03 (nearest hundredth )
Answer: 6 months
Step-by-ste
462=(10,500)(0.88)t
462=924t
462/924=t
0.5=t
So the loan was 0.5 year's
Since we assume that there are 12 months in a year, the loan was 0.5 .12=6 months
