Based on what we established about the classification of x and using the closure of integers, what does the equation tell you about the type of number x must be for the sum to be rational? What conclusion can you now make about the result of adding a rational and an irrational number?

Answer:

SSS

Step-by-step explanation:

it means side side side and the lines represent their congruecny with the other triangle, meaning that the two line dash is equal to the other two line dash and the one line dash is equal to the other one line dash and you know the last side is the same with eachother because they are sharing that side of the triange

Answer: x = 5.625

Step-by-step explanation:  The triangles are similar; the side lengths of the large triangle are proportional to the lengths of the small triangle. The corresponding parts are proportional.

Use proportion. The total length of side FV is 16.

6:16 = x:15 . or 6/16=x/15

cross multiply 15 × 6 = 90, then divide 90/16

90/16 = x

5.625 = x

Answer: b=112 degrees and c=68

Step-by-step explanation:

Answer:

b = 112, c = 68

Step-by-step explanation:

The angle of a line is 180 degrees.

If an angle is 112, 180-112=68 so that blank space will be 68 degrees.

180-68=112, so b=112.

Since b is 112, we now that c is 68.

The quadrant of P' is (-3 , 2).

Here,

Point P is located at (–3, –2).

Point P is reflected across the x-axis to create P'.

We have to find the quadrant of P'.

What is Reflection across x-axis?

A point after reflection across the x-axis, the x- coordinate remains the same but y - coordinate is taken to be the additive inverse.

Now,

Point P is located at (–3, –2).

Point P is lie on third coordinates.

And, P is reflected across the x-axis to create P'.

Hence, Point P' is lie on second coordinates.

Since, The rule of the reflection across x- axis is,

(x, y) → (x, -y)

Hence, Quadrant of P' = (-3, -(-2)) = (-3, 2)

Therefore, The quadrant of P' is (-3 , 2).

Answer:

There were 35 children and 38 adults at the pool that day.

Step-by-step explanation:

You can use substitution to solve this answer. When solving equations with substitution, ask yourself "how many?" and "how much?" to create two equations:

1.25c+2.25a=126.25  (this equation tells us the dollar value)

c+a=73.   (this equation tells us quantity, or how many)

1. Solve for 1 variable and plug it into the other equation.

a=73-c   -----> 1.25c+2.25(73-c)=126.25

2. Simplify the equation above.

1.25c+164.25-2.25c=126.25

3. Simplify even more:

-1c+164.25=126.25

4. Subtract 164.25 from both sides to get:

-1c=-38

5. Divide both sides by -1.

c=38 (this means that there are 38 children)

6. Plug the new value for c back into the equation c+a=73.

38+a=73

7. Subtract 38 from both sides to solve for a:

a=35 (this means that there are 35 adults)

The option that negates the given statement is; F: Two segments do not have the same measurement.

In Mathematics, the negation of a statement simply means the opposite of the given mathematical statement. Thus, “X” is a statement, then the negation of statement X is represented by ~X.

Now, we are given the statement;

"Two segments are the same measurement."

Now, for two segments to be the same measurement it means that they are equal and congruent and could possibly measure the same degree, However, it can never mean that they do not have the same measurement.

Thus, the option that negates the given statement is; F: Two segments do not have the same measurement.

Answer:

x = 10

y = 5

Step-by-step explanation:

Let the two numbers be x and y

Difference between the two is 10

x-y = 10

Sum;

x+ y is four times the smallest number

Let the smaller number be y

x+ y = 4y

Subtracting equation ii from i

-2y = 10 -4y

4y-2y = 10

2y = 10

y = 10/2

y = 5

Recall;

x-y = 10

x = 10 + y

x = 10 + 5 = 15

Answer:

we conclude that:

If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.

Step-by-step explanation:

We know that the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p".

In other words, it is symbolically represented as:

' ~q ~p is the contrapositive of p q '

For example, the contrapositive of "If it is a rainy day, then they suspend the match" is "If they do not suspend the match, then it won't be a rainy day."

Given

p: 2x -5=5

q: 4x-6=14

As the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p

Thus, we conclude that:

If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.

Step-by-step explanation:

the answer is that you add all of them

The factors of the model x^2-9x+14 is (x-2) and (x-7)

The model is x^2-9x+14

Factoring the expression, we get

x^2-7x-2x+14=0

x(x-7)-2(x-7)=0

(x-2)(x-7)=0

The factors of the given model is (x-2)(x-7)

To check if it is a factor or not substitute x=2

2^2-9(2)+14=4-18+14=4-4=0

So x-2 is a factor of the model

7^2-9(7)+14=49-63+14=49-49=0

So x-7 is also a factor of the given model

Answer:

25 meals

Step-by-step explanation:

If Rita feeds her dog 2/5 pounds of dog food for each meal, this means;

2/5 pounds = 1 meal

To get the number of meals she will feed if she buys 10 pounds, we will say;

10 pounds = x meals

Divide both equations to get x;

(2/5)/10 = 1/x

Cross multiply;

2/5 x = 10 * 1

2x/5 = 10

2x = 50

x = 50/2

x = 25

Hence the 10pounds food will last 25 meals
