25/28=375/x. Use equivalent ratios to solve the proportion.

The solution of the given equation xy-7y=49 for y is y = 49/(x-7) for all values of x not equal to 7.

To solve the equation xy-7y=49 for y, first we can factor out y from the left side of the equation which gives us y(x-7)=49.

Then we can isolate y by dividing both sides of the equation by (x-7).

This gives us y = 49/(x-7).

This solution assumes that x is not equal to 7 because division by zero is undefined.

Hence, the solution is y = 49/(x-7) for x ≠ 7.

The value of the unknown number is 36. 2 1/9 of 36 is 76.

Given the parameter:

2 1/9 of what number is 76?

To solve for the unknown value, first, convert the mixed fraction to an improper fraction:

2 1/9 = ( 9×2 + 1 )/9 = 19/9

Now, we set up the equation:

Let 'x' represent the unknown number:

19/9 of x is 76

19/9 × x = 76

Solve for x:

19x/9 = 76

19x = 9 × 76

19x = 684

x = 684/19

x = 36

Therefore, the value of x is 36.

Answer:

$137.5

Step-by-step explanation:

First, you need to divide $162.50 by 6.5

If you divide correctly you should get 25

Since that month she got an increase, which means you have to subtract 25 from $162.50.

Answer: $137.5

The Difference between Rational numbers and Irrational numbers are given as follows

Rational numbers =   A number of the form [tex]\dfrac{p}{q}[/tex]  when [tex]q\neq 0[/tex] is called as a Rational number

Example = Any fraction of the form p/q such as 2/3 , -3/11 and 5/12

Irrational number =  A number that can not be expressed in the form of [tex]\dfrac{p}{q}[/tex]  or nor it can be represented as a recurring  decimal form then it is called as Irrational number

These are of the form [tex]\sqrt[n]{x}[/tex] where we can not simplify positive integer x

Example = [tex]\sqrt{2}[/tex] ,  [tex]\sqrt{3}[/tex] ,[tex]\sqrt[3]{5}[/tex]

These both types of numbers belong to the category of Real numbers as they fall on Real number line.

Rational numbers  with denominators = 1 are called as Integers

Surds are the categories of Irrational numbers  are

Surds  are the values of square root of any positive number that can not be simplified further to a whole number

Some examples of Surds are [tex]\sqrt{2}[/tex] and [tex]\sqrt{3}[/tex]

The equation 6+7+7+6 demonstrates the Commutative Property of addition, which states that the order of addition does not affect the sum.

The property shown by the equation 6+7+7+6 is the Commutative Property of addition. This property states that the order in which two numbers are added does not affect the sum. In other words, A+B = B+ A. Specifically here, the numbers 6 and 7 are added together in an order that can be rearranged without changing the result, indicating the commutative nature of their addition. To visualize:

Both expressions yield the same sum, showing the commutative property.

Answer:

Positive integer

Step-by-step explanation:

An integer is a collection of positive and negative number and zero

Positive Numbers:  Positive number are the numbers which have positive sign. For example 4, 9 or which which represents positivity like gain , increase, profit etc

Negative numbers: Negative number are the numbers which have negative sign. For example -4, -9 or which which represents negativity like loss , decrease etc

Zero is neither a negative number nor a positive number.

13 yard is a positive because there is a gain , which represent positivity.

We can also write + 13 yard.

Hence, the correct answer is it is a positive integer

(C) Base angle theorem

Step-by-step explanation:

Given: JKLM is an isosceles trapezoid, KL ∥ JM  

Prove: KM ≅ JL

Proof:

Statements                                                                 Reasons

1. JKLM is an isosceles trapezoid, KL ∥ JM               Given

2. JK ≅ LM                                                definition of isosceles trapezoid

3.  KL ≅ KL                                                          reflexive property

4. ∠JKL ≅ ∠MLK                                          Base angle theorem (base=LK)

5. △JKL ≅ △MLK                                                       SAS rule

6. KM ≅ JL                                                                  CPCTC  

Hence proved.

therefore, option C is correct.

The missing reason for statement 4, is: C. base angles theorem.

The base angle theorem states that the two base angles in an isosceles triangle that are opposite the congruent sides are equal in measure or congruent.

Thus, ∠JKL and ∠MLK are base angles of the identified isosceles triangle, therefore, the missing reason for statement 4, is: C. base angles theorem.

A. 4r = v

Step-by-step explanation:

the amount of salad Reagan ate is r.

If Olivia ate 4 times as much salad as Reagan, then she ate r amount multiplied by 4:

4r

Thus, the equation than can be used to describe the amount of salad for Olivia is:

4r = v

This is because this equation tells us that 4 times the amount of salad Reagan ate (4r) is equal to what Olivia ate (v)

To divide 3,050 by 10 to the second power, simply move the decimal point two places to the left, resulting in the answer 30.50.

When dividing by powers of 10, you simply need to move the decimal point to the left by the number of zeros in the exponent. In this case, the exponent is 2, so you would move the decimal point two places to the left.

Therefore, 3,050 divided by 10 to the second power is equal to 30.50.
