(Ignore Lol) hdhdjdhdh D. 27/4! (:
Step-by-step explanation:
given :
A=5x - 10
B = 3x
C= 2x - 10
solution:
A+B+C = 180°
5x - 10 + 3x+ 2x - 10 = 180
10x -20 = 180
10x = 200
x = 20
A = 5(20)-10 = 100-10 = 90°
B = 3x = 3(20) = 60°
C = 2x-10 =2(20)-10 =40-10 = 30°
this is the right triangle and scalene triangle
Answer:
27is answer
Step-by-step explanation:
x+ x - 14 = 40
or, 2x = 40+ 14
or, 2x = 54
or, x = <u>5</u><u>4</u>
2
or, x= 27
Answer:
B) y=12x
Step-by-step explanation:
We are given with the coordinates 
Where 
represents the number of days.
represents the number of likes she got.
To model the equation using Kyle's data we find the slope using the given coordinate.
Let us say 
and 
Slope 
formula , 
Plug in the above points now, we get
Now we use the point-slope formula, 
Plugging the corresponding values.
Thus option is B is the correct answer.
Answer: See below
Explanation:
3x - 4y = 13 (1)
2x + y = 5 (2)
——————
3x - 4y = 13
4(2x + y = 5) (2) times 4
——————-
3x - 4y = 13
8x + 4y = 20
——————-
11x = 33
x = 33/11
x = 3
Plug x = 3 in (2):
2(3) + y = 5
6 + y = 5
y = 5-6
y = -1
Thus, x = 3 and y = -1
