Joseph and Wendy were catching tadpoles. At first Wendy caught nine times three more than Joseph caught. Joseph was upset and released half of Wendy 's tadpoles, and then six times as many as Joseph caught swam away. After all of this, Wendy only had three tadpoles left. How many tadpoles did Joseph catch?

Answers

Answer 1

Answer:

Joseph caught 7 tadpoles

Step-by-step explanation:

Let the number of tadpoles caught by Joseph be x

The number of tadpoles Wendy caught will be ;

9(x + 3)

After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;

Hence, mathematically;

9(x + 3)/2 - 6x = 3

Multiply through be 2

9(x + 3) - 12x = 6

9x + 27 -12x = 6

9x -12x = 6-27

3x = 21

x = 21/3

x = 7

Answer:

M∪N = {1, 2, 3, 4, 5, 6, 7, 11, 12}M∩N = {2, 3}

Step-by-step explanation:

GivenM = {Prime integers between 1 and 11} and N = { factors of 12}To findM∪N M∩NSolution

Sets in full are

Prime numbers up to 11 ⇒ M = {2, 3, 5, 7, 11}Factors of 12 ⇒ N = {1, 2, 3, 4, 6, 12}

Combined set

M∪N = {1, 2, 3, 4, 5, 6, 7, 11, 12}

Common set

Me up rich goes to the skate park and tents a skateboard for 4.00 per hour they make him rent a helmet for one time 6.00 fee if he only has $30 to spend at the park then select the equation that can be used to calculate h the number of hours he can rent the skateboard

Answers

Let, x be the maximum hours he can rent skate board and helmet.

So, total price :

T = 4x + 6x

Now, it is given that he has only $30.

Therefore,

Total price should be less than or equal to $30.

4x + 6x ≤ 30

10x ≤ 30

x ≤ 3

Therefore, the maximum number of hours he can rent the skateboard is 3 hours.

Hence, this is the required solution.

is 6.1 or 6.18 bigger and how you know which one is larger.

Answers

Answer:

  6.18 is larger

Step-by-step explanation:

Written with an equivalent number of decimal places, we are comparing ...

  6.10

  6.18

__

Use these rules for comparison of positive numbers:

1. If the left-most non-zero digits are in number places with different place values, the one with the digit in the highest place value is larger.

2. If the left-most non-zero digits are in number places with the same place value, the number with the larger digit is larger.

3. If the left-most non-zero digits are in the same number place and have the same value, replace those digits with 0, and repeat the comparison starting with the first test above. If one of the numbers has no more non-zero digits, use zero. If both of the numbers have no more digits, they are equal--neither is larger.

__

Following the above rules, we compare the units digits to find they are the same.

Then we compare the tenths digits, and find they are the same.

Then we compare the hundredths digit of 6.18 to 0 to find that 8 > 0, so 6.18 > 6.1

_____

Alternatively (for numbers of any sign), subtract one number from the other. If the result is positive, the minuend is larger. If the result is negative, the subtrahend is larger. If the result is zero. the numbers are equal.
