Question:

Steve uses 14 blue beads and 6 green beads to make a bracei. Which ratio compares the number of blue beads to the total number of beads in one bracelet?

A. 14:6

B. 6:14

C. 6:20

D. 14:20

Answer:

D. 14:20

Step-by-step explanation:

So basically we are provided with 14 blue beads and 6 green beads. So, we can say that total number of beads is 20 which is the sum of blue beads and green beads. And we are asked to compare the ratio of number of blue beads to the total number of beads in one bracelet.

From above we can say that total number of beads in one bracelet is 20 (14 + 6 = 20 or Sum of blue beads + Sum of green beads). Therefore,

→ Blue beads : Total number of beads in one bracelet = 14 : 20

<u>Correct option is option D. 14:20.</u>

A movie streaming website charges an initial fee of $80, plus $4 for each movie that is streamed. How many movies must be stream
pochemuha

Answer:

80 movies must be streamed.

Step-by-step explanation:

To find the average cost, you must divide the total cost by the number of movies watched.

When you watch 1 movie, you pay the initial fee of $80 plus a $4 purchase of the film.

The equation is shown as such:

average cost = (total cost)/(number of movies)

Your total cost can be represented as 4x + 80, while the number of movies is represented as x.

You want the average to equal 5, so your equation is shown as follows:

5 = (4x+80)/x

simplifying this, we get

5 = 4 + \frac{80}{x}

which can then be simplified to

1 = \frac{80}{x}

X = 80 movies.

Writing and Solving an Equation to Find Negative Integers Two negative integers are 5 units apart on the number line, and their
Shtirlitz [24]

Answer:

-23

Step-by-step explanation:

Let first negative integer = x

The second = x +5

Their product = 126, hence,

x * (x +5) = 126

x^2 + 5x = 126

x^2 + 5x - 126 = 0

Two numbers whose product gives - 126 and sun gives 5

x(x + 14) - 9(x+14) =0

(x - 9) = 0 or (x + 14) = 0

x = 9 or x = - 14

Since x is said to be a negative integer,, the our x = - 14

First integer = - 14

Second integer = (x + 5) = (-14 + 5) = - 9

Sum of both integers :

-14 + - 9 = - 23
