bob has three times as many baseball cards as bill together they have 68 cards how many cards does bob have
Write the equations representing what you know, then solve: Bob = 3 * Bill Bob + Bill = 68
Bob = 68 - Bill but Bob also = 3 * Bill so 68 - Bill = 3 * Bill Add Bill to both sides and divide both sides by the right number to get Bill = ? Then plug that value into Bob + Bill = 68 to find out how many Bob has.
i dont no how to solve it im so cionfused with math
68 - Bill = 3 * Bill Add Bill to both sides (doing the same thing to both sides of the equation doesn't change the truth) 68 - Bill + Bill = Bill + 3*Bill 68 = 4*Bill Now divide both sides by 4 to find out the value of Bill 68/4 = Bill = ?
new question raul is 5 years older than twice carlos age the sum of their age is 101 what is carlos age
What did you get for your answers in the previous one? You should really post separate questions in separate posts. Again, write equations for what we know. Raul = Carlos * 2 + 5 Raul + Carlos = 101 Here we could substitute Carlos * 2 + 5 wherever we see Raul in the second equation: Carlos * 2 + 5 + Carlos = 101 Carlos * 3 + 5 = 101 Carlos * 3 + 5 - 5 = 101 - 5 Carlos * 3 = 96 Carlos = ?
