Answer:
0
Step-by-step explanation:
2x-6=2x+15
2x-2x=15+6
0x/0=21/0
x=0
Answer:
11
Step-by-step explanation:
First, we need to find the other angles. We'll do this by subtracting 180-141, giving us 39. This is one of the angles needed.
Next, we'll find the other angle by subtracting 180-127, giving us 53.
Now, we can set up the expression: 39 + 53 + 8y = 180
Adding like terms: 92 + 8y = 180
Now, subtracting 180-92 to give us 8y = 88
Diving both side by 8, gives us the value of y = 11.
In triangle b. we know that tan(x) = Opposite side to x angle / Adjacent side to angle x.
By substituting in above formula,
tan(x) = 12/5 = 2.4
x = tan^-1(2.4) = 68 degrees.
And in triangle a. i am not clear with the angle. Is it 51 or any other?
Sum/Difference of 2 monomials is (in simplest terms) a monomial when the 2 monomials are 'like terms
The system:
y = 3 x - 7
15 x - 5 y = 14
---------------------
Using the substitution method:
15 x - 5 · ( 3 x - 7 ) = 14
15 x - 15 x + 35 = 14
0 · x = 14 - 35
0 · x = - 21
x , y ∈ ∅
