Laura goes to the carnival and receives 60 tokens to play games.
•each game required 4 tokens.
•At the end of the evening she used all of her tokens,how many games did laura play?
A.10
B.15
C.16
D.24​

Answers

Answer: (B) 15

Step-by-step explanation:

Laura had 60 tokens to use and each game required 4 of them. By the end of the evening all of her tokens had been spent.

Let x represent the number of games Laura has played. Since Laura used up all of her tokens we can determine that for some integer x, 60 - 4x = 0

Solve for x

60 - 4x = 0

- 4x = - 60

x = [tex]\frac{60}{4}[/tex]

x = 15

Therefore, Laura played 15 games by the end of the evening

Answers

Answer:

x = 14

Step-by-step explanation:

Given that,

2:7 is expressed in the form for 4:x.

We need to find the value of x.

2:7 must be equated to 4:x.

So,

[tex]2:7=4:x\\\\or\\\\\dfrac{2}{7}=\dfrac{4}{x}\\\\x=\dfrac{7\times 4}{2}\\\\x=14[/tex]

When you translate, you add or subtract the value you are moving to each coordinate

(6,7) left 5 would be -5 to the x coordinate and 3 up would be +3 to the y coordinate.

6-5=1

7+3=10

new point is (1,10)

moving left 5 units is subtracting 5 from the x value:

6-5 = 1

Moving up 3 units is adding 3 to the y value:

7 + 3 = 10

The answer is (1,10)

A factory produces blue pens and black pens. Each week, 2/3 of the pens produced at the factory are black.

Write and solve an equation that can be used to determine the number of blue pens (x) produced at the factory in a week when 45,000 pens are produced.

Answers

Answer:

15,000

Step-by-step explanation:

1/3 times 45,000 = 15,00

The number of blue pens produced at the factory in a week when 45,000 pens are produced is 15,000.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

A factory produces blue pens and black pens.

2/3 of the pens produced at the factory are black.

If T is the total pens produced at the factory, then the number of black pens produced is 2/3 T.

Number of blue pens = T - 2/3 T = 1/3 T

Given that,

Total pens produced = 45,000

Equation to find the number of blue pens is,

x = 1/3 × 45,000

Solving,

x = 15,000

Hence the number of blue pens produced is 15,000.

Step-by-step explanation:

The diagonal of the square is they hypotenuse of an isosceles right triangle with sides of 16 inches. The Pythagorean theorem tells you its length (d) is ...

  d^2 = 16^2 +16^2 = (16^2)(2)

Taking the square root, we have ...

Marco is turning the expression (x-4)^2 into a trinomial. He writes down what is shown below. What is his error?

=x^2-4x-4x+16
=x^2-8x+16
it’s +16, not negative. he forgot that when you add two negatives together, it becomes positive.

Answer:

Step-by-step explanation:

first, let's solve the equation ourselves.

(x-4)^2= (x-4)(x-4)= x^2−8x+16

now, we can see what's different about the two.

we can say that Marco's answer had the number 16 as a negative, when it was supposed to be positive. Marco wrote the incorrect sign.


The function P(x) = 0.75x - 96 models the relationship between the number of pretzels x that a certain vendor sells and the profit the vendor
makes. Find P(500), the profit the vendor makes from selling 500 pretzels.

Answers

Answer:

279

Step-by-step explanation:

First, you plug in 500 for " x " because it says P( 500 ).

P( 500 ) = 0.75 (500) -96

Then, you multiply / simplify

P ( 500 ) = (375) - 96

P ( 500 ) = 279

Finally, it gives you your answer for selling 500 pretzels

C) $326.85
D) $359.00


PLEASE HELP

Answers

Answer:

$314.15 (A)

Step-by-step explanation:

We start by subtracting the 15% discount. 15% can be represented by 0.15, and 100% can be represented by 1. So therefore, the new price of the TV will be 1-0.15 = 0.85 of the original price using just the 15% discount. Therefore, 0.85 x 399 = $339.15. We then take this number and subtract another $25 to get $314.15
