Answer:
x=-2
Step-by-step explanation:
Hey there!
In order to solve this equation, you need to combine like terms
The equation after combining the x terms and the contants will look like this
10x+3=12x+7
Now you have to take 10x away from both sides
3=2x+7
Now bring all the constants to the left side
3-7=2x
Simplify
-4=2x
divide 2 on both sides to get x by itself
x=-2
So, the answer is x=-2
Step-by-step explanation:
-5n-10=10
-5n=10+10

n=20/-5
n=-4

Answer:
According to the pythogorean theorem, this triangle is not a right triangle.
Cross multiply
19(x) = 30(9.5)
Simplify
19x = 285
Divide 19 from both sides
19x/19 = 285/19
x = 285/19
x = 15
B. 15 is your answer
hope this helps
