Kasey had 45 tickets for games at the school carnival . She used 1/3 of her tickets to play the spin the wheel game. She used 1/3 of the remaining tickets to play a balloon game ,where she won 8 more tickets . How many things cleats did Kacey have after playing these two games?

Answers

23; 45(1/3) + 45(1/3)=30. 45-30=15. 15+8 (the tickets she won) =23.
45 original tickets then 1/3 goes away. Find that answer mathematically. then subtract your answer from 45 to get the remaining 2/3. Those are the used playing the balloon game. I am not sure what it means by cleats...

Explain why 17 tens. and 1 hundred 7 tens have the same value

Answers

we know that

1\ tens=10 \n1\ hundred=100

so

1) the expression 17\ tens is equal in numbers to

17\ tens=17*10=170

2) the expression 1\ hundred\ 7\ tens is equal in numbers to

1\ hundred\ 7\ tens=1*100+7*10=100+70=170

therefore

17\ tens and 1\ hundred\ 7\ tens have the same value
because 1 hundred and 7 tens equal 170
and 17x10 equals 170

Greatest common factor of 21, 35, 49

Answers

The greatest common factor of 21, 35, and 49 is 49, which is determined by the prime factorization.

To find the greatest common factor (GCF) of 21, 35, and 49, we can start by finding the prime factorization of each number.

Here are the prime factorizations of the given numbers:

  • 21 = 3 x 7
  • 35 = 5 x 7
  • 49 = 7 x 7

To find the GCF, we need to identify the common prime factors and multiply them together.

Here, the only common prime factor is 7, which appears twice in the prime factorization of 49.

Therefore, the GCF of 21, 35, and 49 is 7 x 7 = 49.

So, the greatest common factor of 21, 35, and 49 is 49.

I think it is 7 because 7 x 3 = 21
7 x 5 = 35
7 x 7 = 49

1/5(2x-15) + 3/5x = 4 1/4

x=?

Answers

1/5(2x-15) + (3/5)x = 4 1/4
x*2/5 - 15/5 + x*3/5 = 4 1/4
x*2/5 - 3 + x*3/5 = 4 1/4
x*(2/5+3/5) - 3 = 4 1/4
x*(5/5) - 3 = 4 1/4
1*x - 3 = 4 1/4
x= 4 1/4 + 3
x= 7 1/4
