<span>You paint 1313 of a wall in 1414 hour.
Now we need to find the rate in order you to paint one wall.
1313 : 1414 = 1 : X
1414 = 1313 X
X = 1.08
So the rate per one wall is 1.08 hours.</span>
X=7
Explanation:
A triangle equals 180°, and they gave us one length already, and it says the one arm of the triangle is equal to the other so we know that the third angle is going to be the same as the second angle.
180=90+(6x+3)+(6x+3)
Combine like terms
180=96+12x
Subtract 96 from both sides
84=12x
Divide 12 by both sides
7=x
Now check it,
90+(6*7+3)+(6*7+3)
90+(45)+(45) =180
I need to know the rest of the question in order to help you! :D
I believe it’s the last answer the fourth one
