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

What is 180(n-2)=s when solving for N
Answer:
n = s/180 +2
Step-by-step explanation:
180(n-2)=s
Distribute
180n - 360 =s
Add 360 to each side
180n -360+360 = s+360
180n = s+360
Divide each side by 180
180n/180 = s/180 + 360/180
n = s/180 +2

Answer:
[tex]L = 0.83\ in[/tex]
Step-by-step explanation:
Given
Width = 1.2 in when Length = 1 in
Required
Determine the length when width = 1 in
First, we need to determine the ratio:
[tex]Ratio = \frac{Width}{Length}[/tex]
[tex]Ratio = \frac{1.2}{1}[/tex]
[tex]Ratio = 1.2[/tex] --- (1)
Let the required Length be represented with L
So:
[tex]Ratio = \frac{Width}{Length}[/tex]
[tex]Ratio = \frac{1}{L}[/tex] --- (2)
Equate (1) and (2)
[tex]\frac{1}{L} = 1.2[/tex]
Multiply through by L
[tex]L * \frac{1}{L} = 1.2 * L[/tex]
[tex]1 = 1.2 * L[/tex]
Divide through by 1.2
[tex]L = \frac{1}{1.2}[/tex]
[tex]L = 0.83\ in[/tex] (Approximated)

I have to find rs and rt
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]
20
We can also find ST.
4(12)-8 [multiply]
48-8 [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
Answer:
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
Hence the value of z is 9

5. A restaurant orders 132 bags of flour. Each box contains 4 bags of flour. Write an equation that
you can use to solve x the number of boxes they receive. Solve the equation.
132/4 = 33, x = 33 boxes
Answer:
4x=132
you divide by 4 on both side
x should be by it self
x=132/4
x=33
If you want make a harder equations use this
4x+10=142
subtract 10 9n both side
-10+10 +4x= 142-10
4x=132
divide by four on both side
x=132/4
x=33
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
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]

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.
