Answer:
Step-by-step explanation:
Angle 1 and Angle 2 are identified as vertical pairs
Answer:
well 21% of 30 is 6.3 so then you have to do 6.3x12 Because there are 12 months in a year. so 6.3x12=75.6 then if you want to round up it would be 76
Step-by-step explanation:
I HOPE THAT THIS HELPSSSS :)
Answer:
(4x -14)/3
Step-by-step explanation:
Assuming you intend mixed number coefficients, only the coefficients of x can be combined.
(-2 1/4)x +(3 7/12)x -(4 2/3) = x(-2 1/4 +3 7/12) -(4 2/3)
The mixed numbers are added in the usual way.
(-2 1/4) +(3 7/12) = (-2 +3) +(-1/4 +7/12) = 1 +(-3/12 +7/12) = 1 4/12 = 1 1/3
So the expression simplifies to ...
(1 1/3)x -(4 2/3)
This might be better written as ...
(4x -14)/3

<em>Comment on mixed numbers</em>
It is hard to write mixed numbers so they can be properly interpreted in an algebraic expression. In general, they are better written as improper fractions or as decimal numbers (if the decimal terminates).
