show that the angles of an equalateral triangle are 60°each​

Answers

Answer:

For an equilateral triangle, we know that all 3 sides of the triangle are equal. Accordingly, all the 3 sides of the equilateral triangle hold equal angles.

Since, we know, that the sum of all angles of any triangle be 180° .

Let each angle be a.

Thus,

Hence, we can show that all the 3 angles of an equilateral triangle hold equal angles; i.e. 60°.

Liliana buys some softballs at $3 each and gloves at $20 each for her PE
class. She buys twice as many balls as gloves. She spends $138 in total,
which includes $8 tax: Which equation would you use to find the number of
gloves she buys?
Let x represent the number of gloves she buys.
A. 2 + 2x + 8 = 138
B. 20 (2x) + 3 (x) + 8 = 138
C. 20 (2) + 3 (2x) + 8 = 138
D. 20 (x) + 3(2x) = 138

Answers

Answer:

d. 20(x)+3(2x)=138

ap3x

The number of gloves she buys is B. 20 (2x) + 3 (x) + 8 = 138, where x = 3.

What are linear equation?

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

Now it is given that,

Cost of each softball , $3.

Cost of each gloves, $20 .

Total money spend , $138 .

Tax , $8 .

She buys twice as many softballs as gloves.

To Find the number of gloves she buys .

Let , x represent the number of gloves she buys.

So , number of softballs she buys is 2x .

20 (2x) + 3 (x) + 8 = 138

or, 40x + 3x + 8 = 138

or, 43x + 8 = 138

Subtract 8 both the side we get,

43x = 130

or, x = 3.02

0r, x = 3

Hence,the number of gloves she buys is B. 20 (2x) + 3 (x) + 8 = 138, where x = 3

Find the slope of the line passing through the points (-18, -5) and (-19, -13)​

Answers

Answer:

Let (-18, -5) be (x1,y1)

(-19, -13) be (x2,y2)

slope = (y2-y1)/(x2-x1)= (-13+5)/(-19 +18) = 8

Answer: The slope is 8.

Step-by-step explanation: To get the slope you have to do y2 - y1 over x2 - x1. so you take the -5 and subtract -13 from it, which equals 8. Then subtract -19 from -18 which is 1. So you have 8/1 which is 8.

Steve can do are; A.Create a pair of equations same slope and different y-intercepts. D. Create a pair of lines that will always stay the same distance apart.

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have given that Steve wants to create a system of equations so that the system has no solution.

We know that when both the lines(represented by both the equations) are parallel and not coincident, then that system of linear equations have no solutions as there is no common point on both line.

So the correct option that steve can do are;

A.Create a pair of equations same slope and different y-intercepts.

D. Create a pair of lines that will always stay the same distance apart.

I NEED TO KNOW NOW IT'S DUE!!

Last summer, Fred earned 16 dollars per day, and Maria earned 18 dollars per day together, they earned 1780 dollars. If Fred worked 5 more days than Maria, how many days did Maria work?​

Answers

x = # of days Maria worked

x + 5 = # of days Fred worded

$16(x + 5) + $18x = $1780

Let's distribute the $16

$16x + $80 + $18x = $1780

Combine like terms

$34x + $80 = $1780

Subtract $80 from both sides.

$34x = $1700

Divide both sides by $34

x = 50 days

Maria worked 50 days

I have to find rs and rt ​

Answers

Answer:

RS= 20

ST= 40

RT=60

Step-by-step explanation:

If you notice, RS and ST make up RT. Therefore, we add RS and ST, and set that equal to RT.

3x-16+4x-8=60               [combine like terms]

7x-24=60                        [add both sides by 24]

7x=84                              [divide both sides by 7]

x=12

Now that we know x, we can plug them into RS.

3(12)-16                          [multiply]

36-16                              [subtract]

Suppose S is between R and T. Use the Segment Addition Postulate to solve for z.. RS=2z+6, ST=4z−3, RT=5z+12

Answers

9

Step-by-step explanation:

If S is between R and T, then RS+ST = RT

Given the following parameters

RS=2z+6,

ST=4z−3,

RT=5z+12

On substituting

2z+6+4z-3 = 5z+12

Collect like terms

2z+4z-5z = 12+3-6

6z-5z = 15-6

z = 9

Maya painted 3/4 of her art project in the morning and 1/8 of her project in the evening which equation can Maya use c to find how much of the project she painted

Answers

The equation to find the proportion painted is: [tex]\mathbf{c = \frac{7}{8}x}[/tex]

Let the size of the art be x.

In the morning, she paints 3/4 of x.

So, we have:

[tex]\mathbf{Morning = \frac 34 x}[/tex]

In the evening, she paints 1/8 of x.

So, we have:

[tex]\mathbf{Evening = \frac 18 x}[/tex]

So, the amount of project painted is:

[tex]\mathbf{c = Morning + Evening}[/tex]

This gives

[tex]\mathbf{c = \frac 34x + \frac 18x}[/tex]

Take LCM

[tex]\mathbf{c = \frac{6x + x}8}[/tex]

Add the numerator

[tex]\mathbf{c = \frac{7x}8}[/tex]

So, we have:

[tex]\mathbf{c = \frac{7}{8}x}[/tex]

Hence, the equation to find the proportion painted is: [tex]\mathbf{c = \frac{7}{8}x}[/tex]
