The two numbers are 23 and 28

Step-by-step explanation:

We are given that

[tex]X = Y + 5\\and\\(X+Y) + 9 = 60\\X+Y = 51\\(Y+5) + Y = 51\\2Y + 5 = 51\\2Y = 46\\Y = 23\\\\X = Y + 5\\X = 23 + 5\\X = 28[/tex]

Answer:

7 days

Step-by-step explanation:

If there are 9 pages left, that means you have already read 70 pages.

Since you read 10 pages a day, we can find how many days you have been reading the book by dividing 70 by 10:

70/10

= 7

This means you have been reading the book for 7 days

Answer:

7 days

Step-by-step explanation:

With 9 pages left take 79-9 to get 70 pages.

70 pages at 10 pages a day is 70/10 and you get 7 or 7 days.

Answer:

A: (3x+24):3x = 85:51

Step-by-step explanation:

85 seems to be the total (RT + TP). 51 seems to be just TP alone.

This means that for the side lengths above, it should be in this format:

(length of QP):(length of SP)

The length of QP is 3x+24, as 3x is SP and QS is 24.

The length of SP is just 3x.

I hope this made sense, please leave a comment if it didn't ^^'

Answer:

∆RPQ ~ ∆TPS

now

RP: TP=QP:SP

(34+51);51=(3x+24):3x

(3x+24):3x=85:51 is your answer

Answer:

The solution to the system of equations is x = 4 and y = 2.

Step-by-step explanation:

From statement we know that the first line is [tex]y = 0.5\cdot x[/tex]. The second line is determined by knowing two distinct points and solving the resulting system of equations by definition of the equation of the line:

[tex](x_{1},y_{1}) = (3,1)[/tex] and [tex](x_{2}, y_{2}) =(-5,-7)[/tex]

[tex]3\cdot m + b = 1[/tex] (1)

[tex]-5\cdot m + b = -7[/tex] (2)

The solution of the system of equations is:

[tex]m = 1[/tex], [tex]b = -2[/tex]

The second line is represented by [tex]y = x-2[/tex]. And the resulting system of equations is:

[tex]0.5\cdot x -y = 0[/tex] (3)

[tex]x-y = 2[/tex] (4)

The soltuion to the system of equations is:

[tex]x = 4[/tex], [tex]y = 2[/tex]

The solution to the system of equations is x = 4 and y = 2.

Answer:

d = dependant; t = independant

Step-by-step explanation:

The d value is dependant on the t value, therefore it is the dependant. The t is the only valuable that can be changed in the equation, therefore being the independant.

Answer:

[tex]D[/tex] = dependent; [tex]t[/tex] = independent

Step-by-step explanation:

[tex]D[/tex] is the independent variable since its value relies/depends on the value of [tex]t[/tex].

[tex]t[/tex] is the independent variable since it is the input variable which can be changed.

Answer:

A.) 8.5 miles

Step-by-step explanation:

I think its a because it says "THE SHORTEST possible" distance between the houses. So A.) 8.5 miles is the correct answer because A.)8 .5 miles is the shortest answer in the list of answers.

Hope this helped.

The shortest distance between the two houses is 13 miles.

In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

By observing the diagram we conclude that the shortest distance is the hypotenuse of the right-angled triangle that will form.

Given, The base is 12 miles and the height is 5 miles.

Therefore by Pythagoras' theorem,

Hypotenuse = √(5² + 12²).

Hypotenuse = √(25 + 144).

Hypotenuse = √(169).

Hypotenuse = 13 miles.

So, The shortest distance between the houses is 13 miles.

Sure whats the problem?

The value of the expression 5³ is 125.

We have,

The concept used in calculating the value of 5 raised to the power of 3 is exponentiation.

In mathematics, exponentiation is an operation that involves raising a base number to a certain power.

The base number (in this case, 5) is multiplied by itself repeatedly, where the number of times it is multiplied is determined by the exponent (in this case, 3).

When we raise 5 to the power of 3, we can interpret it as multiplying 5 by itself three times:

5³ = 5 x 5 x 5  = 125

So, the concept of exponentiation allows us to quickly calculate the result of multiplying a number by itself multiple times, where the exponent indicates the number of repetitions.

Thus,

The value of the expression 5³ is 125.

Answer: 3ab   IF a^b does NOT mean a to the power of b!

I believe you mean  9a²b and 30ab³

If you really mean 9aᵇ and 30ab³,  then the GCF is 3a.

Step-by-step explanation:

the factors of  9 are 3*3  The factors of 30 are 2*3*5.

The only common factor of 9 and 30  is 3

a is a common factor of a and a²

b is a common factor of b and b³

Answer:

P

Step-by-step explanation:

P tells us that the Domain: 3,-1,4,2 doesn't repeat

Q does repeat its Domain: 7,5,-1,5

Reminder that in order for a line of ordered pairs to be a function the domain number Shouldn't repeat, That doesn't mean that the range cant repeat.

Example: (5,-3), (5,9) Not a function

                (-1,-6), (7,-6) Function

Out of the two set given, the set of ordered pairs that represents a function is: P = {(3, 5), (−1, 5), (4, −6), (2, 9)}.

A set of ordered pairs that has one exact y-value assigned to each x-value is considered a function.

In set P, all x-values has exactly one y-value, while in set P, the x-value, 5, has two different y-values, 9 and -3.

Therefore, the set of ordered pairs that represents a function is: set P.
