Answer:
5/4 + -x/3
Step-by-step explanation:
Operations on how to solve this problem:
1. Multiply the numbers.
2. Combine multiplied terms into a single fraction
3. Add the numbers
(To guide you to the answer, look at the file I uploaded)
1. Find the Greatest Common Factor (GCF)
GCF = 2
2. Factor out the GCF (Write the GCF first)
2(14a/2 + 8/2)
3. Simplify each term in parentheses
2(7a + 4)
Answer:
2400 coins
Step-by-step explanation:
What we should do is calculate the Least Common Multiple of 80 and 75, since each of us put together a group with this amount of coins, this way we will know the amount of coins when they are equal.
To obtain the L.C.M
you have to factor both numbers and multiply the numbers whose exponent is the highest, it looks like this:
75 = 5 ^ 3
80 = 2 ^ 4 * 5
We multiply those with the highest exponent,
5 ^ 3 = 75
2 ^ 4 = 16
75 * 16 = 1200.
L.C.M. is 1200.
Since they tell us that they have less than 2000 coins, this is the correct answer, because when assembling these groups in this way, they coincide again in 2400, which is over the limit.
So, each one has 1200 coins, in total it would be:
1200 * 2 = 2400
Between them they have a total of 2400 coins
