in one baseball season, Peter hit twice the difference of the number of home runs Alice hit and 6. Altogether, they hit 18 home runs. how many home runs did each player hit that season?
Answers
Answer 1
Answer:
Let Peter's hit be x and Alice's runs be y. x = 2(y - 6) . . . (1) x + y = 18 . . . (2)
Putting (1) into (2) gives, 2y - 12 + y = 18 3y = 18 + 12 = 30 y = 30/3 = 10 x = 2(10 - 6) = 2(4) = 8
Therefore, Peter hit 8 home runs and Alice hit 10 home runs.
Remember order of operations. Please (Parenthesis and brackets) Excuse (exponents) My (multiplication) Dear (Division) Aunt (Add) Sally (Subtract). Also remember that multiplication and division as well as addition and subtraction should go from left to right. So if you were to do this problem first I'd convert the fraction 1/10 to a decimal. That's like saying 1 in 10 or 10%. So it should convert to .10 x 6 = 0.60 and don't forget to multiple 7 x1000 next. (Left to right). 7,000. So it becomes 5+10+0.60+7,000 then add. 7,015.60 is your answer.
