Answer:

B (780 4/5)

Step-by-step explanation:

He’s buying 24 boxes, and each box weighs 3 1/5 pounds. So we need to multiply 24 x 3 1/5, resulting in 780 4/5

So sorry if I’m wrong. Have a good day!

Answer:

The answer is 57.7 x.

Step-by-step explanation:

Answer:

Tracy most likely saw 13 cars, and 13 motorcycles. Other solutions that you can find are: average number of tires in the area, the mode number of tires in the area (see the most often), etc.

Step-by-step explanation:

2x + 4x = 78

2(13) + 4(13) = 78

As 13 and 13 are two prime numbers, the answer will be 13.

Answer:

Simplify the expression.

7x2+14x−3

Step-by-step explanation:

The required simplification can be given as 7x²+ 14x - 3

What is simplification?

The operation in mathematics to process and interpret the relation to make function simple or more simple is called simplify and the phenomenon is called simplification.

We have,
= (5x² + 8x - 3) + (2x² - 7x + 13x)

= 5x²+ 2x²+ 8x - 7x + 13x - 3
= 7x²+ 14x - 3

Thus, the required simplification can be given as 7x²+ 14x - 3

Distributive property

Step-by-step explanation:

when you distribute the left sid dit equals the right

Step-by-step explanation:

Simplifying

4x + -5 = 20x

Reorder the terms:

-5 + 4x = 20x

Solving

-5 + 4x = 20x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-20x' to each side of the equation.

-5 + 4x + -20x = 20x + -20x

Combine like terms: 4x + -20x = -16x

-5 + -16x = 20x + -20x

Combine like terms: 20x + -20x = 0

-5 + -16x = 0

Add '5' to each side of the equation.

-5 + 5 + -16x = 0 + 5

Combine like terms: -5 + 5 = 0

0 + -16x = 0 + 5

-16x = 0 + 5

Combine like terms: 0 + 5 = 5

-16x = 5

Divide each side by '-16'.

x = -0.3125

Simplifying

x = -0.3125

Answer:

31/14

Step-by-step explanation:

We first need to get common denominators, so we multiply the 16 and the 7 by 2, to get 32/12. Now we can subtract since the fractions have common denominators. After subtracting we get 31/14 or 2 3/14. Hope this helps!

Answer:

- 29

Step-by-step explanation:

Step 1:

- 16 - ( - t ) = - 45       Equation

Step 2:

- 16 + t = - 45      Open Parenthises

Step 3:

t = - 45 + 16      Add 16 on both siddes

Answer:

t = - 29

Hope This Helps :)

Answer:

t = -29

Step-by-step explanation:

Step 1: Write equation

-16 - (-t) = -45

Step 2: Solve for t

Step 3: Check

Plug in t to verify it's a solution.

-16 - (-(-29)) = -45

-16 - 29 = -45

-45 = -45

Answer:

1/4 pound(s) of candy in each bag

Step-by-step explanation:

3 1/2 (pounds of candy) ÷ 14 (goodie bags) = ?

To make this easier let's turn 3 1/2 into a improper fraction and flip 14/1 (14/1 to 1/14):

3 1/2 = 7/2       14/1 = 1/14

Now we multiply:

7/2 x 1/14 = 7/28 = 1/4

(When you divide fractions, you can flip the second fraction and multiply and get your answer. Remember to simplify once you get your answer!)

Hope I helped! Sorry if wrong!

Answer:

50 cats would take 6 hours to catch 75 rats.

Step-by-step explanation:

After reading the statement we noticed the existence of two relationships:

1) The amount of cats is directly proportional to the quantity of caught rats.

2) The amount of cats is inversely proportional to time taken to catch rats.

That is to say:

[tex]n \propto \frac{x}{y}[/tex]

[tex]n = k\cdot \frac{x}{y}[/tex] (Eq. 1)

Where:

[tex]n[/tex] - Amount of cats, dimensionless.

[tex]x[/tex] - Amount of caught rats, dimensionless.

[tex]y[/tex] - Time, measured in hours.

[tex]k[/tex] - Proportionality ratio, measured in hours.

Then, we obtain the following relationship by eliminating the proportionality ratio in (Eq. 1):

[tex]\frac{n_{1}\cdot y_{1}}{x_{1}} = \frac{n_{2}\cdot y_{2}}{x_{2}}[/tex] (Eq. 2)

Where:

[tex]n_{1}[/tex], [tex]n_{2}[/tex] - Initial and final amounts of cats, dimensionless.

[tex]x_{1}[/tex], [tex]x_{2}[/tex] - Initial and final amounts of caught rats, dimensionless.

[tex]y_{1}[/tex], [tex]y_{2}[/tex] - Initial and final times, measured in hours.

Now we clear final time in (Eq. 2):

[tex]y_{2} = y_{1}\cdot \left(\frac{n_{1}}{n_{2}} \right)\cdot \left(\frac{x_{2}}{x_{1}} \right)[/tex]

By knowing that [tex]y_{1} = 2\,h[/tex], [tex]n_{1} = 12[/tex], [tex]x_{1} = 6[/tex], [tex]n_{2} = 50[/tex], [tex]x_{2} = 75[/tex], then we get that time taken by 50 cats to catch 75 rats is:

[tex]y_{2} = (2\,h)\cdot \left(\frac{12}{50} \right)\cdot \left(\frac{75}{6}\right)[/tex]

[tex]y_{2} = 6\,h[/tex]

50 cats would take 6 hours to catch 75 rats.
