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

The pizza shop is running a special: 2 medium pizzas

pizzas?

Answers

Answer:

41.94

Step-by-step explanation:

12 divided by 2 is 6 and six times 6.99 gets you your answer of 41.94

Answer:

$72.00

Step-by-step explanation:

Lets round $6.99 to $7.00. Now we have an easier number to work with.

To find the total price of 12 , we need to multiply $7.00 by 12.

⇒ $7.00 x 12 = $84.00

Since we added 1 cent to $6.99 and multiplied by 12, we need to sutract 1 times 12.

1 x 12 = 12

$84 - $12 = $72.00

Find the x and y intercept of the following equation 4x-10y=20

Answers

For the given linear equation we have:

y-intercept: y = -2x-intercept: x = 5.

How to find the intercepts for the linear equation?

Here we have a linear equation:

4x -10y = 20

First, let's find the y-intercept, this is the point with x = 0, so evaluating in that we get:

4*0 - 10y = 20

-10y = 20

y = 20/-10

y = -2

The x-intercept is what we get by evaluating in y = 0.

4x - 10*0 = 20

x = 20/4

x = 5

New York City is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 3 vans and 14 buses with 509 students. High School B rented and filled 12 vans and 10 buses with 472 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.

Answers

Answer:

Step-by-step explanation:

Let's say :

v = number students in van, b = number of students in bus

From the info provided in the question:

High school A takes 3 vans and 14 buses for 509 students

We can write this as:

3v + 14b = 509

You can re-write this as :

3v = 509 - 14b

We also know High School B takes 12 vans and 10 buses for 472 students:

12v + 10b = 472

Since we already know that 3v = 509 - 14b , substitute this equation into the above formula and you get:

12v + 10b = 472

4(509 - 14b) + 10b = 472

2036 - 56b + 10b = 472

2036 - 46b = 472

2036 - 472 = 46b

1564 = 46b

Divide both sides by 46 to find "b".

b = 1564/ 46 = 34

Therefore the number of students that fit in each bus is 34.

So since we know b = 34, substitute b into the equation at the top:

3v = 509 - 14b

3v = 509 - 14(34)

3v = 509 - 476 = 33

Divide both sides by 3 to find "v".

v = 33/3 = 11.

Therefore the number of students in each van is 11.
