Answer:
x=75º definition of an isosceles triangle or Base angle Theorem
y=60º definition of complementary angles
Step-by-step explanation:
180-75-75=30
90-30=60
Some schools call theorems and deffintions by other names, but I tried to give you the ones that are most commonly used in all schools.
Answer:
y = 90, x= 105
Step-by-step explanation:
Total number of sides = ( n-2)180
n = number of sides
(4-2)180
2× 180=360
y is a right angle triangle = 90°
x=90+90+75+x= 360
255+x=360
x= 360-255
= 105

given the equation y+9=-3(x-4) what point does the line pass through?
Answers
Answer:
(0,-5)
Step-by-step explanation:
First you want to simplify this equation by distributing the 3 into x-4:
y+9 = -3x+4
Next subtract 9 from both sides:
y= -3x -5
Now since I am assuming you want the Y-Intercept because you didn't ask for a specific point then it passes through the Y axis at the point (0,-5)

Answer:
11) x = -1
12) y = 8
13) j = 155
14) g = -4
15) x = 18
Step-by-step explanation:
11) 2(x - 3) = -8
x - 3 = -4
x = -4 + 3 = -1
12) y + 3 = -2y + 27
3y = 24
y = 8
13) 2j - 3 + 3j = 2 (341 + 45)
5j - 3 = 2(386)
j = 155
14) 2(g + 1) = 3(g + 2)
2g + 2 = 3g + 6
-4 = g
15) 25 = 4/3 x + 1
25 - 1 = 4/3 x
24 = 4/3 x
18 = x
x = 18

The difference between Lily's age and twice Kenny's age is 6 years. Lily is older than Kenny. Let x represent Lily's age and y represent Kenny's age.
What is the equation?
Answers
If x represents Lily's age and y represents Kenny's age. The equation representing the given condition is x-2y=6.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
Given that, there are 6 years between Lily and Kenny, who are twice her age. Kenny is younger than Lily. Let x and y stand in for Lily's and Kenny's ages, respectively.
Let x represent Lily's age and y represent Kenny's age.
If the difference between Lily's age and twice Kenny's age is 6 years.
x-2y=6
If Lily is older than Kenny.
x>y
Thus, if x represents Lily's age and y represent Kenny's age. The equation representing the given condition is x-2y=6.

CAN ONE OF YALL HELP PLEASE I NEED THESE RIGHT TO GET THE PLEASE I KNOW YALL CAN HELP!!
Answers
Step-by-step explanation:
(x1,y1) = (-2,5)
(x2,y2) = (5,-2)
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y - 5)/(-2 - 5) = (x + 2)/(5 + 2)
(y - 5)/-7 = (x + 2)/7
(y - 5)/-1 = (x + 2)/1
y - 5 = -(x + 2)
y - 5 = -x - 2
y = -x -2 + 5
y = -x + 3
Ashton had $60 to take shopping with her. She bought a dress for $16.50, a pair of shoes for $12.25, and 3 head bands for $2.25 each. She paid a 6% sales tax on all of the items she bought. How much money did Ashton have left?
Answers
Answer:
$22.37
Step-by-step explanation:
[Total Cost] 16.5 + 12.25 + (3)2.25 = $35.50
[Sales Tax] 6% -> 0.06
35.5 * 0.06 = 2.13
35.5 + 2.13 = $37.63
[Money Left] 60 - 37.63 = $22.37

The carnival fundraiser at Westville Elementary School raised $300 on Friday. On Saturday, the carnival will raise 480 percent of that amount. Which statements are true about the amount of money that the carnival will raise on Saturday? Check all that apply.
The answer will be less than $300 because 100 is less than 480.
The answer will be greater than $300 because 480 is greater than 100.
(100)(3) = 300, so 480(3) is the amount of money that the carnival will raise on Saturday.
480 + 300 is the amount of money that the carnival raised on Saturday.
The carnival raised $780 on Saturday.
