Is it true 4 and -4 have a sum of 0

Mathematics
1 answer:
mafiozo [28]3 years ago
3 0

Answer:

Yes, 4 + -4 = 0.

Think of it like a number line: The number four is 4 units to the right of the center which is 0, and the number negative four is 4 units to the left of the center. When you add them together, those distances cancel out, and you just get 0.

Tom has 2 8-foot long boards he needs to cut pieces that are 15 inches long. How many 15 inch pieces can he cut from the two boa
Ksju [112]

Answer:

Tom can cut 12 (15 inch pieces) from the two boards.

Step-by-step explanation:

We're first given foot measurements and we're asked to find the answer in inches. That means we must convert 8 feet to inches, which is a 1:12 inches conversion. 8 times 12 will give you 96, so now you will multiply that value by 2 because Tom has 2 8-foot long boards. That will give you 192 inches. Since the question is asking for 'how many 15 inch pieces he can cut from the two boards?', you will need to divide 192 inches by 15 to find the answer. This will give you 12.8 boards. Because you can't have parts of an object, the answer will be 12 whole boards.
