Marissa rode her bike to the park and back home. She lives 2 3/10 miles from the park. How many miles did Marissa ride her bike in all?

Answers

Answer 1
Answer:
If she rides twice the amount of 2 3/10 miles, then she rides 2.3 miles × 2, so that is 4.6 miles, which is 4 6/10 miles, which becomes 4 3/5 miles once simplified. The ending answer is that Marissa rode her bike 4 3/5 miles in all.

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 9 row of the same length, he has 3 chairs left over. If he arranges the chairs in 7 rows of that same length, he has 19 left. How many chairs does Liam have?

Answers

Let the number of chairs in a row be x, then the total number of chairs is 9x + 3 = 7x + 19. i.e. 9x + 3 = 7x + 19; 9x - 7x = 19 - 3; 2x = 16 x = 16/2 = 8. Thus there are 8 chairs in each row. Therefore, the total number of chairs is given by 9(8) + 3 = 72 + 3 = 75.I hope that my answer is helpful! Let me know if you need something more :)

(100 - 16)÷2 = 42 is the short one's length and 42 + 16 = 58 is the long one's length
Problema Solution a wooden board 100 centimeters long is cut into two pieces. One piece is 16 inches longer than the other. What are the lengths of the two pieces x = the length of one piece y = the length of the other piece the total length is 100 cm this means x + y = 100 one piece is 16 inches longer than the other first we need to convert inches to cm: 1 in = 2.54 cm 16 in = 2.54*16 = 40.64 now we can write x = y + 40.64 by solving the system of equations x + y = 100 x = y + 40.64 we find x = 70.32 cm y = 29.68 cm the lengths of the two pieces are 70.32 cm and 29.68 cm.

What's a better definition for prime factorization to help me understand it??

Answers

It's really simple, a prime number is simply a number that can only be DIVIDED by 1 or itself. So 5 can't be divided by anything but 5 or 1. Now going from this when doing Prime FACTORIZATION, you have to find 2 numbers that multiply to the number you were given. Let's say your told to find the prime factor of 12. What divides into it? Well 6x3 does but 6 is not a prime number. But 2x2x3 = 12 and it uses only prime numbers. Hope this helps!
