Answer:
x = 2
Step-by-step explanation:
8x + 5 = 3x + 15
8x - 3x + 5 = 3x - 3x + 15
5x + 5 = 15
5x + 5 - 5 = 15 - 5
5x = 10
5x / 5 = 10 / 5
x = 2
It is hard to see but the first one is 243xy^6/5
Answer:
2x^2+14x+5
Step-by-step explanation:
x^2+9x+5x+5
Combine Like Terms:
=2x^2+9x+5x+5
=(2x^2)+(9x+5x)+(5)
=2x^2+14x+5
Equation - x = -3/10 + (10－1）
The original number is 9.3 because
x = -3/10 + (10－1）
x = -3/10 + 9
x = 9.3
Hello from MrBillDoesMath!
Answer:
sin(A) = k/c
sin(C) = k/a
Discussion:
By definition of sine
,
sin(A) = side opposite angle / hypotenuse = k/c
sin(C) = side opposite angle/ hypotenuse = k/a
Added remark:
From the first equation, k = c sin(A). From the second equation k = asin(C). Hence.
asin(C) = csin(A) => divide both sides by "ac"
sin(C)/ c = sin(A)/a
Which is the law of sines for a triangle.
Thank you,
MrB
