The answer is
26 degrees
I just did the test hope this helps :)
28x + 44y = 964.40
21x + 33y = 723.30
Let's multiply the first equation by 4 and the second by -4
84x + 176y = 3857.6
-84x - 132y = -2893.2
Add the equations together.
0 + 44y = 964.4
Simplify
44y = 964.4
Divide both sides by 44
y = 964.4/44
Since we have the value of y, let's plug 964.4/44 into y for the first equation.
28x + 44(964.4/44) = 964.40
Simplify the left side
28x + 964.4 = 964.4
Subtract 964.4 from both sides
28x = 0
Divide both sides by 0
x = 0
In conclusion,
y = 964.4/44
x = 0
Answer:
-2/5
Step-by-step explanation:
p(x) = 5x + 2
plug p(x) = 0
5x + 2 = 0
5x = - 2
x = - 2/5
Answer:
n=8
Step-by-step explanation:
6(n-4)=3n
6n-24=3n
-24=-3n
n=8
Answer:
Since the equation is undefined for -2
Therefore, NO SOLUTION for the given equation.
Step-by-step explanation:
Considering the expression





as
so equation becomes











So the following points are undefined

Since the equation is undefined for -2
Therefore, NO SOLUTION for the given equation.
