Answer:
3

You need to first subtract everything on the numerator by changing the fractions in the numerator. Each fraction should have a similar denominator. You should end up getting 24/10, simplifying it down to 12/5. After that you multiply the fractions in the denominator part, due to the key word “of” indicating that you need to multiply. Once you do that you have your numerator and denominator simplified down from each equation, you then simplify down further.

A bag contains three red marbles, two green ones, one lavender one, four yellows, and five orange marbles. HINT [See Example 7.
lilavasa [31]
<h2>Answer:</h2>

<em><u>Number of possible sets = 4</u></em>

<h2>Step-by-step explanation:</h2>

In the question,

Number of Red marbles in the bag = 3

Number of Green marbles in the bag = 2

Number of Lavender marbles in the bag = 1

Number of Yellow marbles in the bag = 4

Number of Orange marbles in the bag = 5

So,

If we need to form a set having all the red marbles then,

We have 3 Red marbles and only the set of 4 is needed to be made.

For that,

We have <u>4 different options,</u>

1 Green + 3 Red

1 Lavender + 3 Red

1 Yellow + 3 Red

and,

1 Orange + 3 Red.

<em><u>Therefore, there are only 4 such cases which include all the Red marbles in them.</u></em>

Two people started from the same point at the same time and traveled in opposite directions. One traveled at 60 mph and the othe
erma4kov [3.2K]
To find the distance traveled, we multiply the speed by the time. In this case, one person travels 60t miles in one direction, and the other person travels 50t miles in the other direction. So at any time t, the distance between the two people is 60t + 50t = 110t.

Given that the distance between them is 440 miles, we can solve for t with the following equation:

110t = 440

t = 4 hours

HELP NEEDED!
Ilia_Sergeevich [38]

Answer:

x = 12.6

Step-by-step explanation:

Sum of measure of all the arcs of a circle = 360°

m(arc CD) + m(arc CED) = 360°

Since, m(arc CED) = (20x)°

And m(arc CD) = (8x + 6)°

By substituting these measures in teh expression,

(20x)° + (8x + 6)° = 360°

(20x + 8x) + 6 = 360

28x = 360 - 6

28x = 354

x = \frac{354}{28}

x = 12.64

x = 12.6
