Answer:

[tex]\boxed {\boxed {\sf ( - \frac{9}{2}, -1) \ or \ (-4.5, -1) }}[/tex]

Step-by-step explanation:

We are asked to find the midpoint of a line segment. When you find the midpoint, you essentially find the average of the x-coordinates and the y-coordinates. The midpoint formula is:

[tex](\frac {x_2+x_1)}{2}, \frac{y_2+y_1}{2})[/tex]

In this formula, (x₁, y₁) and (x₂, y₂) are the endpoints of the line segment. we are given the endpoints R (-6, 1) and S (-3, -3). If we match the value and the corresponding variable we see that:

Substitute the values into the formula.

[tex]( \frac{-3 + -6}{2} , \frac{ 1+ -3}{2} )[/tex]

Solve the numerators.

[tex](\frac {-9}{2}, \frac {-2}{2})[/tex]

Divide.

[tex]( - \frac {9}{2}, -1})[/tex]

The fraction can also be written as a decimal.

[tex](-4.5 , -1)[/tex]

The midpoint of the line segment RS is (-9/2, -1) or (-4.5, -1).

Answer:Complementary angles are two angles whose sum is 90 degrees.

Let x represent one of the angles.

The other angle which is 84.2 degrees less would be x - 84.2.

Using this, we can write an equation.

x + (x-84.2) = 90.

Combine like terms:   2x - 84.2 = 90

Add 84.2 to both sides of the equation.

2x = 174.2

Divide by 2:  x = 87.1  

and x - 84.2 would equal 2.9.       to check: does  87.1 + 2.9 = 90?  yes.

Answer:

The second and third boxes. m=-10/4 & -5/2 & the last one

Step-by-step explanation:

We know the answer is negative so we need to add a larger number to get the 3/4 to the negatives. 3-10= -7, so -10/4 and -5/2 is equal to -10/4

Answer:

The second one m= -10/4, the third one m= -5/2, and the last one -5/4+m= -15/4

Step-by-step explanation:

You find m by solving -7/4 - 3/4 = m. Thats the second option -10/4.

When you simplify, you get -5/2, the third option.

Finally, -5/4+m= -15/4 is equal to -15/4 -(-5/4)=m. Subract and you get -10/4. That makes the original equation equal to the last option.

Answer:

B. 63 x 10,000 = 630,000 is the only true equation

Step-by-step explanation:

Trial and error

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The correct option is B.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

From the given equation that is true are,

A. 63 x 103 = 63,000

If we multiply 63 and 103 the product will be 6,489. Since the two sides of the equation are not true, therefore, the given equation is false.

B. 63 x 10,000 = 630,000

If we multiply 63 and 10,000 the product will be 630,000. Since the two sides of the equation are true, therefore, the given equation is true.

C. 63 x 102 = 630

If we multiply 63 and 102 the product will be 6,426. Since the two sides of the equation are not true, therefore, the given equation is false.

D. 63 x 1,000 = 6,300

If we multiply 63 and 1,000 the product will be 63,000. Since the two sides of the equation are not true, therefore, the given equation is false.

E. 63 x 105 = 6,300,000

If we multiply 63 and 105 the product will be 6,615. Since the two sides of the equation are not true, therefore, the given equation is false.

Hence, the correct option is B.

Step-by-step explanation:

The ratio of cats to dogs at a pet store is 4:5. It means that if there are 4 cats in the store then there are 5 dogs, if there are 8 cats(4×2) there then there will be 10 dogs(5×2).

The number of cats is 16 if the ratio of cats to dogs is 4:5 if there are 20 dogs.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The complete question is:

The ratio of cats to dogs is 4;5 if there are 20 dogs. How many cats are there?

It is given that:

The ratio of cats to dogs at a pet store is 4:5

Let 4x be the cats and 5x be the dogs

5x = 20

The above equation is a linear equation in one variable.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

x = 20/5

x = 4

Number of cats = 4x

Plug x = 4 in the above expression:

= 4(4)

= 16

Thus, the number of cats is 16 if the ratio of cats to dogs is 4:5 if there are 20 dogs.
