When you raise a negative integer (in this case -1) to an even integer (30), the end result will be positive (1), but when you raise it to an odd integer (31), the end result will be negative (-1). The sign of the product fluctuates between positive and negative depending on the type of integer it’s raised to.
Answer:
Step-by-step explanation:
2 1/2 + x = 5 1/3 Change the mixed numbers to improper fractions
5/2 + x = 16/3 The lowest common multiple is 6. Multiply by 6
5*3 + 6x = 16*2
15 + 6x = 32 Subtract 15 from both sides.
6x = 32 - 15
6x = 17 Divide by 6
6x/6 = 17/6
x = 2 5/6
Check
5/2 + 17/6 = 16/3
15/6 + 17/6 = 32/6
32/6 = 32/6 The question checks.
1. divide 75 by 15. this equals 5. multiply 5 by 3 to get 15.
the answer is 3 baseballs
2. 3 buses every 10 minutes. 60 minutes in a hour. multiply 3 by 6 to get 18 buses per hour.
We can set the 2nd equation to y that way we have something to solve for
First we solve our first equation by moving the one to the other side
Then we divide by 3 on each side
So now we can plug 4 into the x's of the 2nd equation
