12.6+4m=9.6+8m what does m=

Answer:

8.6

Step-by-step explanation:

To find the distance between two points we use the formula posted below

All we need to do is figure out what the points are on the graph and plug them into the formula... we end up with

the square root of (5-(-2)^2+(2-(-3)^2 and get the answer of 8.602325267

then we round to the nearest tenth and get 8.6

The orders are 1 stay the same. 2 change to 4, 3 change to 2, 4 change to 3, and 5 stays the same.

Multiple: 1/ 8 & 2/ 4  = 1 · 2/ 8 · 4  = 2/ 32  = 1 · 2/ 16 · 2  = 1/ 16   Multiply both numerators and denominators. Result fraction keep to lowest possible denominator (lowest=2). In the next intermediate step , cancel by a common factor of 2 gives 1/ 16 .  In words - one eighth multiplied by two quarters = one sixteenth.

Final result: 1/16

Answer: C

Step-by-step explanation: there are 4 different variables (x, y, a, and b)

Answer:

y = -2x + 12

Step-by-step explanation:

Step 1: find the slope

y = 1/2x + 5

The equation of the line is

y = mx + c

m - slope

m = 1/2

Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other

m = -2

Step 2 : using a point slope form

y - y1 = m( x - x1)

( 2 , 5)

x1 = 2

y1 = 5

y - 2 = -2( x - 5)

y - 2 = -2x + 10

y = -2x + 10 + 2

y = -2x + 12

The equation of the line is

y = -2x + 12

A movie theater has 7 seats in the front row  

12 seats in the middle row

11 seats in the back row

Probability first person who enters the theater will be in the middle row

[tex]P=\frac{\text{No. of middle seats}}{\text{total seats}}[/tex]

Answer:

Option C : 173.8 km² is the correct answer.

Step-by-step explanation:

Given that:

Side length = 6 kilometers

A shape with 8 sides is called an octagon, therefore, the given figure is an octagon.

Area of octagon is given by;

Area = [tex]2(1+\sqrt{2})a^2[/tex]

Putting a=6

Area = [tex]2(1+\sqrt{2})(6)^2[/tex]

Area = [tex](2+2\sqrt{2})(36)[/tex]

Area = 173.82

Rounding off to one decimal place

Area = 173.8 km²

Hence,

Option C : 173.8 km² is the correct answer.

Answer:

12 pieces

Step-by-step explanation:

Total length of the board = 48 in

It must be divided into 4 pieces of equal length

This means, there will be 3 cut to have 4 pieces

Each cut will cause a waste of 3/16 in.

Total waste = 3 cut × 3/16 in

= (3*3)/16

= 9/16 in

Length of board remaining = Total length of the board - Total waste

= 48 - 9/16

= (768-9)/16

= 759/16 in

How long will each piece be after the cuts are made?

Length of each piece after the cut = Length of board remaining / 4

= 759/16 ÷ 4

= 759/16 × 1/4

= 759/64

= 11.859375

Approximately 12 pieces to the nearest whole number

Answer:

87 degrees

Step-by-step explanation:

the three angles of a triangle add up to one hundred eighty degrees.

1. Add the degrees of the known angles together

56 + 37 = 93

2. Since a triangle adds up to one hundred eighty degrees, you would subtract your known degrees from the total

180 - 93 = 87

Answer:

y=1, x=2

Step-by-step explanation:

so first solve for y. plus x=3y-1 into the other equation.  

so 3(3y-1)+4y=10.  

Simplify

9y-3+4y=10           Add 3 to both sides

9y+4y=13               Add

13y=13 .                  Divide 13 from both sides

y=1

Plug 1 into the first equation.  

x=3(1)-1

x=3-1

x=2 and y=1

Answer:

Part A; 15x

Step-by-step explanation:

Part A; 15(67)

= $1005

Part B; ??

The number of tickets to be sold if, The cost of the banquet hall is $500, The cost per ticket is $15, the Total money to be raised is $1000, is 67, and the equation is given by 1000 = 15x.

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.

In other terms, it is a mathematical statement stating that "this is equivalent to that."

Given:

The cost of the banquet hall = $500,

The cost per ticket = $15,

Total money to be raised = $1000

Write the equation of the number of tickets as shown below,

1000 = 15x

Here, x is the number of tickets,

x = 1000 / 15

x = 66.67 or 67

Answer:

10.77

Step-by-step explanation:

by using Pythagoras theorem we can find the distance between the points,

so...

distance between the points, which is the hypotenuse will be xy

difference between the y coordinates will be dy

difference between the x coordinates will be dx

according to pythagoras theorem,

[tex]xy^{2} = dx^{2} + dy^{2} \\xy^{2} = (-6-(-2))^{2} + (-5-5)^{2}\\xy^{2} =(-4)^{2} +(-10)^{2} \\xy^{2} =16+100\\xy^{2} =116\\xy =\sqrt{116} \\xy=10.77[/tex]

Yes. The ratios of towers to customers​ (thousands) are all equivalent to a unit rate of nothing. Therefore, option A is the correct answer.

Proportional relationships are relationships between two variables where their ratios are equivalent.

The given table is

Cell Phone Towers          Customers​ (thousands) Towers

        3.25                                          169

        4.25                                          221

        5.25                                          273

        7.25                                          377

Here, the ratio of Cell Phone Towers : Customers​ (thousands) Towers

3.25 : 169

= 325/16900

= (325÷325)/(16900÷325)

= 1/52

4.25 : 221

= 425/22100

= 1/52

5.25 : 273

= 525/27300

= 1/52

7.25 : 377

= 725/37700

= 1/52

Therefore, the ratio of given cell phone towers to customers​ (thousands) towers are equivalent.
