Answer:

ummm I think u want the answer x= 11 1/4

Answer:

x = 45/4

Step-by-step explanation:

4(x - 5) = 25

4x - 20 = 25

4x - 20 + 20 = 25 + 20

4x = 45

4x/4 = 45/4

x = 45/4

Answer:

S-8=9

or, s= 9+8

or, S= 17

Because 8 is in - so to become it's positive sign we should bring it to right hand side

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.

Answer:

  27

Step-by-step explanation:

Evaluating this expression according to the order of operations is a straightforward calculator problem.

  = (81 ÷ 27)³ = 3³ = 27

__

You can also use the rules of exponents to simplify this before evaluating.

  (a^b)^c = a^(bc)

  (a^b)/(a^c) = a^(b-c)

__

  = ((3²)² ÷ 3³)³ = (3⁴ ÷ 3³)³ = (3¹)³ = 3³ = 27

Solve for x first.

5x - 9 + 2x + 10 = 78

7x + 1 = 78

7x = 78 - 1

7x = 77/7

x = 11

Then substitute the value of x to find DE.

DE = 5x - 9

5(11) - 9

55 - 9

DE = 46

Therefore, the value of DE is 46

DF= 78, DE = 5x -9, EF = 2x + 10, find DE.

First, solve for the value of x.

Then, plug and substitute the value of x to find the DE.

Step-by-step explanation:

Opposite rays make a 180 degree line.

For naming it, always start with the endpoint and then to the arrow.

Dividing the segments and finding the lengths, it is found that the distance between the two cities is of 130 miles.

--------------------------------

[tex]ad = ab + bc + cd[/tex]

--------------------------------

[tex]ab = 5bc[/tex]

In terms of x, [tex]bc = x, ab = 5x[/tex]

--------------------------------

[tex]bc = 2cd[/tex]

In terms of x, [tex]cd = \frac{x}{2}[/tex]

--------------------------------

[tex]\frac{x}{2} = 10[/tex]

[tex]x = 20[/tex]

--------------------------------

[tex]bc = x = 20[/tex]

[tex]ab = 5x = 5(20) = 100[/tex]

--------------------------------

[tex]ad = ab + bc + cd = 100 + 20 + 10 = 130[/tex]

The distance between the two cities is of 130 miles.

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:

1≤x<10, meaning x must be greater than or equal to 1 and less than 10

Step-by-step explanation:

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.
