Easy,

23y-(7x-2y)+x

There is an imaginary 1 in front of the parentheses, making it,

23y-1(7x-2y)+x

Now, distribute the 1.

-1*7x= -7x
and
-1*-2y= 2y

Leaving your problem looking like...

23y-7x+2y+x

Combine your apples and oranges.....

25y-6x

Thus, your answer.

There are 42 students on a large bus and the rest are on a smaller bus. If 40% of the students are on the smaller bus how many t

Liono4ka [1.6K]

Answer:

There are 70 students on the two buses, 42 on the large and 28 on the smaller.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of students on the large bus = 42

Number of students on the small bus = 40% of the students

2. How many total students are on the two buses?

For answering the question, we will use the Rule of Three Simple, this way:

42 students are 60% of total students, how much students are the 100%?

Total students = 42 * 100/60

Total students = 4,200/60 = 70

There are 70 students on the two buses, 42 on the large and 28 on the smaller.

The given polygons are similar

Step-by-step explanation:

By observing the given diagrams, we can see that the respective angles are congruent.

Two shapes are said to be similar if they have same shapes or one shape is created by uniformly increasing or decreasing the side of other.

For this purpose we find the scale factor of greater to smaller image, if the scale factor is same for each side then the two shapes are similar

So,

The scale factor is:

$\frac{EF}{AB} = \frac{3}{1} = 3\\\\\frac{FG}{BC} = \frac{9}{3} = 3\\\\\frac{GH}{CD} = \frac{15}{5} = 3\\\\\frac{EH}{AD} = \frac{21}{7} = 3$

We can see that the scale factor is same for all sides.

Hence,

The given polygons are similar
