The sum of and 7x2 is 10x2

Tems11 [23]

Answer:

The missing term is 3x²

Explanation:

Addition and subtraction can only take place between like terms.

For two terms to be like, both the variable and its degree must be the same in both terms

Now, consider the given terms:

First term is 7x² has the variable x with degree 2

The resulting term is 10x² has the variable x with degree 2

This means that the missing term is ax²

We need to get the value of "a"

This is done as follows:

ax² + 7x² = 10x²

x²(a+7) = 10x²

a+7 = 10

a = 10-7

a = 3

Therefore, the missing term is 3x²

Hope this helps :)

You are thinking about the things that can go wrong on your trip home over the Thanksgiving break. You have booked a flight with

shtirl [24]

Answer:

The probability that the person reaches home for the holidays is 0.94.

Step-by-step explanation:

A person wants to go home for Thanksgiving and he has booked a flight with US-Scareways.

It is provided that in 30 percent of the cases the company has canceled the flight you were on.

SO there is 70% chance of reaching home without any difficulties.

In case the flight is cancelled, then as a backup the person's friend Walter offers a ride home.

Walter also has a 80% chance of giving the ride. So there is 20% chance the person will not be able to reach hone if his flight gets cancelled.

Consider the tree diagram below.

The events are:

FC = flight is cancelled

FT = Flight is on time

H = reaches home

Compute the probability that the person reaches home as follows:

P (Reaching Home) = P (H|FC) × P (FC) + P (FT)

$=(0.80\times 0.30) +0.70\\=0.24+0.70\\=0.94$

Thus, the probability that the person reaches home for the holidays is 0.94.

The larger of two supplementary angles is 6 less than 5 times the smaller. Find the measure of the two angles.

zimovet [89]

Answer:

Step-by-step explanation:

Let the two angles be x and y

Then: y = 5x - 6

And x + y = 180° (the of supplementary angle is 180°)

Putting y = 5x - 6

x + 5x - 6 = 180

6x = 180 + 6

6x = 186

x = 186/6

x = 31°

And y = 5x - 6

y = 5(31) - 6

y = 155 - 6

y = 149°

The angles are 31° and 149°
